The advanced circuit design of the AAT3216 provides excellent transient response and fast turn-on ability. The LDO regulator output has been specifically optimized to function with low-cost, low-ESR ceramic capacitors. However, the design will allow for operation over a wide range of capacitor types. The AAT3216 has an integrated Power-OK comparator which indicates when the output is out of regulation. 8 The device enable circuit is provided to shut down the LDO regulator for power conservation in portable products. The enable circuit has an additional output capacitor discharge circuit to assure sharp application circuit turn-off upon device shutdown. This LDO regulator has complete short-circuit and thermal protection. The integral combination of these two internal protection circuits gives the AAT3216 a comprehensive safety system during extreme adverse operating conditions. Device power dissipation is limited to the package type and thermal dissipation properties. Refer to the Thermal Considerations section of this datasheet for details on device operation at maximum output current loads. 3216.2006.01.1.3 AAT3216 150mA MicroPower™ LDO with PowerOK Applications Information To assure the maximum possible performance is obtained from the AAT3216, please refer to the following application recommendations. Input Capacitor Typically, a 1µF or larger capacitor is recommended for CIN in most applications. A CIN capacitor is not required for basic LDO regulator operation. However, if the AAT3216 is physically located more than three centimeters from an input power source, a CIN capacitor will be needed for stable operation. CIN should be located as closely to the device VIN pin as practically possible. CIN values greater than 1µF will offer superior input line transient response and will assist in maximizing the highest possible power supply ripple rejection. Ceramic, tantalum, or aluminum electrolytic capacitors may be selected for CIN. There is no specific capacitor ESR requirement for CIN. However, for 150mA LDO regulator output operation, ceramic capacitors are recommended for CIN due to their inherent capability over tantalum capacitors to withstand input current surges from low impedance sources such as batteries in portable devices. Output Capacitor For proper load voltage regulation and operational stability, a capacitor is required between pins VOUT and GND. The COUT capacitor connection to the LDO regulator ground pin should be made as direct as practically possible for maximum device performance. The AAT3216 has been specifically designed to function with very low ESR ceramic capacitors. For best performance, ceramic capacitors are recommended. Typical output capacitor values for maximum output current conditions range from 1µF to 10µF. Applications utilizing the exceptionally low output noise and optimum power supply ripple rejection characteristics of the AAT3216 should use 2.2µF or greater for COUT. If desired, COUT may be increased without limit. In low output current applications where output load is less than 10mA, the minimum value for COUT can be as low as 0.47µF. 3216.2006.01.1.3 Capacitor Characteristics Ceramic composition capacitors are highly recommended over all other types of capacitors for use with the AAT3216. Ceramic capacitors offer many advantages over their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically has very low ESR, is lower cost, has a smaller PCB footprint, and is non-polarized. Line and load transient response of the LDO regulator is improved by using low ESR ceramic capacitors. Since ceramic capacitors are non-polarized, they are not prone to incorrect connection damage. Equivalent Series Resistance: ESR is a very important characteristic to consider when selecting a capacitor. ESR is the internal series resistance associated with a capacitor that includes lead resistance, internal connections, size and area, material composition, and ambient temperature. Typically, capacitor ESR is measured in milliohms for ceramic capacitors and can range to more than several ohms for tantalum or aluminum electrolytic capacitors. Ceramic Capacitor Materials: Ceramic capacitors less than 0.1µF are typically made from NPO or C0G materials. NPO and C0G materials generally have tight tolerance and are very stable over temperature. Larger capacitor values are usually composed of X7R, X5R, Z5U, or Y5V dielectric materials. Large ceramic capacitors (i.e., greater than 2.2µF) are often available in low-cost Y5V and Z5U dielectrics. These two material types are not recommended for use with LDO regulators since the capacitor tolerance can vary more than ±50% over the operating temperature range of the device. A 2.2µF Y5V capacitor could be reduced to 1µF over temperature; this could cause problems for circuit operation. X7R and X5R dielectrics are much more desirable. The temperature tolerance of X7R dielectric is better than ±15%. Capacitor area is another contributor to ESR. Capacitors that are physically large in size will have a lower ESR when compared to a smaller sized capacitor of an equivalent material and capacitance value. These larger devices can improve circuit transient response when compared to an equal value capacitor in a smaller package size. Consult capacitor vendor datasheets carefully when selecting capacitors for LDO regulators. 9 AAT3216 150mA MicroPower™ LDO with PowerOK POK Output The AAT3216 features an integrated Power-OK comparator which can be used as an error flag. The POK open-drain output goes low when OUT is 6% below its nominal regulation voltage. Connect a pull-up resistor from POK to OUT or IN. A delayed POK signal can be implemented with a capacitor in parallel with the pull-up resistor. LDO regulator to withstand indefinite short-circuit conditions without sustaining permanent damage. No-Load Stability The AAT3216 is designed to maintain output voltage regulation and stability under operational noload conditions. This is an important characteristic for applications where the output current may drop to zero. Enable Function The AAT3216 features an LDO regulator enable/ disable function. This pin (EN) is active high and is compatible with CMOS logic. To assure the LDO regulator will switch on, the EN turn-on control level must be greater than 2.0V. The LDO regulator will go into the disable shutdown mode when the voltage on the EN pin falls below 0.6V. If the enable function is not needed in a specific application, it may be tied to VIN to keep the LDO regulator in a continuously on state. When the LDO regulator is in the shutdown mode, an internal 1.5kΩ resistor is connected between VOUT and GND. This is intended to discharge COUT when the LDO regulator is disabled. The internal 1.5kΩ has no adverse effect on device turn-on time. Short-Circuit Protection The AAT3216 contains an internal short-circuit protection circuit that will trigger when the output load current exceeds the internal threshold limit. Under short-circuit conditions, the output of the LDO regulator will be current limited until the short-circuit condition is removed from the output or LDO regulator package power dissipation exceeds the device thermal limit. Thermal Protection The AAT3216 has an internal thermal protection circuit which will turn on when the device die temperature exceeds 150°C. The internal thermal protection circuit will actively turn off the LDO regulator output pass device to prevent the possibility of overtemperature damage. The LDO regulator output will remain in a shutdown state until the internal die temperature falls back below the 150°C trip point. The combination and interaction between the shortcircuit and thermal protection systems allows the 10 Reverse Output-to-Input Voltage Conditions and Protection Under normal operating conditions, a parasitic diode exists between the output and input of the LDO regulator. The input voltage should always remain greater than the output load voltage, maintaining a reverse bias on the internal parasitic diode. Conditions where VOUT might exceed VIN should be avoided since this would forward bias the internal parasitic diode and allow excessive current flow into the VOUT pin, possibly damaging the LDO regulator. In applications where there is a possibility of VOUT exceeding VIN for brief amounts of time during normal operation, the use of a larger value CIN capacitor is highly recommended. A larger value of CIN with respect to COUT will effect a slower CIN decay rate during shutdown, thus preventing VOUT from exceeding VIN. In applications where there is a greater danger of VOUT exceeding VIN for extended periods of time, it is recommended to place a Schottky diode across VIN to VOUT (connecting the cathode to VIN and anode to VOUT). The Schottky diode forward voltage should be less than 0.45V. Thermal Considerations and High Output Current Applications The AAT3216 is designed to deliver a continuous output load current of 150mA under normal operating conditions. The limiting characteristic for the maximum output load current safe operating area is essentially package power dissipation and the internal preset thermal limit of the device. In order to obtain high operating currents, careful device layout and circuit operating conditions must be taken into account. 3216.2006.01.1.3 AAT3216 150mA MicroPower™ LDO with PowerOK The following discussions will assume the LDO regulator is mounted on a printed circuit board utilizing the minimum recommended footprint as stated in the Layout Considerations section of this document. At any given ambient temperature (TA), the maximum package power dissipation can be determined by the following equation: PD(MAX) = TJ(MAX) - TA θJA Constants for the AAT3216 are TJ(MAX), the maximum junction temperature for the device which is 125°C, and ΘJA = 190°C/W, the package thermal resistance. Typically, maximum conditions are calculated at the maximum operating temperature where TA = 85°C, under normal ambient conditions TA = 25°C. Given TA = 85°C, the maximum package power dissipation is 211mW. At TA = 25°C, the maximum package power dissipation is 526mW. VIN(MAX) = PD(MAX) + (VOUT × IOUT) IOUT + IGND The following is an example for an AAT3216 set for a 2.5V output: VOUT = 2.5V IOUT = 150mA IGND = 150µA VIN(MAX) = 526mW + (2.5V × 150mA) 150mA + 150µA VIN(MAX) = 6.00V From the discussion above, PD(MAX) was determined to equal 526mW at TA = 25°C. The maximum continuous output current for the AAT3216 is a function of the package power dissipation and the input-to-output voltage drop across the LDO regulator. Refer to the following simple equation: Thus, the AAT3216 can sustain a constant 2.5V output at a 150mA load current as long as VIN is ≤ 6.00V at an ambient temperature of 25°C. 6.0V is the absolute maximum voltage where an AAT3216 would never be operated, thus at 25°C, the device would not have any thermal concerns or operational VIN(MAX) limits. PD(MAX) IOUT(MAX) < VIN - VOUT This situation can be different at 85°C. The following is an example for an AAT3216 set for a 2.5V output at 85°C: For example, if VIN = 5V, VOUT = 3V, and TA = 25°C, IOUT(MAX) < 264mA. If the output load current were to exceed 264mA or if the ambient temperature were to increase, the internal die temperature would increase. If the condition remained constant, the LDO regulator thermal protection circuit would activate. To determine the maximum input voltage for a given load current, refer to the following equation. This calculation accounts for the total power dissipation of the LDO regulator, including that caused by ground current. PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND) This formula can be solved for VIN to determine the maximum input voltage. 3216.2006.01.1.3 VOUT = 2.5V IOUT = 150mA IGND = 150µA VIN(MAX) = 211mW + (2.5V × 150mA) 150mA + 150µA VIN(MAX) = 3.90V From the discussion above, PD(MAX) was determined to equal 211mW at TA = 85°C. Higher input-to-output voltage differentials can be obtained with the AAT3216, while maintaining device functions within the thermal safe operating area. To accomplish this, the device thermal resistance must be reduced by increasing the heat 11 AAT3216 150mA MicroPower™ LDO with PowerOK sink area or by operating the LDO regulator in a duty-cycled mode. (VOUT = 2.5V @ 25°C) 3.5 Voltage Drop (V) For example, an application requires VIN = 4.2V while VOUT = 2.5V at a 150mA load and TA = 85°C. VIN is greater than 3.90V, which is the maximum safe continuous input level for VOUT = 2.5V at 150mA for TA = 85°C. To maintain this high input voltage and output current level, the LDO regulator must be operated in a duty-cycled mode. Refer to the following calculation for duty-cycle operation: Device Duty Cycle vs. VDROP 3 2.5 200mA 2 1.5 1 0.5 0 0 IGND = 150µA IOUT = 150mA VIN = 4.2V 10 30 40 50 60 70 80 90 100 Duty Cycle (%) Device Duty Cycle vs. VDROP VOUT = 2.5V (VOUT = 2.5V @ 50°C) PD(MAX) (VIN - VOUT)IOUT + (VIN × IGND) 211mW %DC = 100 (4.2V - 2.5V)150mA + (4.2V × 150µA) %DC = 85.54% 3.5 Voltage Drop (V) %DC = 100 20 3 2.5 200mA 2 150mA 1.5 1 0.5 0 PD(MAX) was assumed to be 211mW. 0 10 20 30 40 50 60 70 80 90 100 Duty Cycle (%) For a 150mA output current and a 2.7V drop across the AAT3216 at an ambient temperature of 85°C, the maximum on-time duty cycle for the device would be 85.54%.

The duty cycles for both output current levels must be taken into account. To do so, one would first need to calculate the power dissipation at the nominal continuous level, then factor in the additional power dissipation due to the short duration, high-current peaks. For example, a 2.5V system using a AAT3216IGV2.5-T1 operates at a continuous 100mA load current level and has short 150mA current peaks. The current peak occurs for 378µs out of a 4.61ms period. It will be assumed the input voltage is 4.2V. First, the current duty cycle in percent must be calculated: % Peak Duty Cycle: X/100 = 378µs/4.61ms % Peak Duty Cycle = 8.2% The LDO regulator will be under the 100mA load for 91.8% of the 4.61ms period and have 150mA peaks occurring for 8.2% of the time. Next, the continuous nominal power dissipation for the 100mA load should be determined then multiplied by the duty cycle to conclude the actual power dissipation over time. 3216.2006.01.1.3 PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND) PD(100mA) = (4.2V - 2.5V)100mA + (4.2V x 150µA) PD(100mA) = 170.6mW PD(91.8%D/C) = %DC x PD(100mA) PD(91.8%D/C) = 0.918 x 170.6mW PD(91.8%D/C) = 156.6mW The power dissipation for 100mA load occurring for 91.8% of the duty cycle will be 156.6mW. Now the power dissipation for the remaining 8.2% of the duty cycle at the 150mA load can be calculated: PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND) PD(150mA) = (4.2V - 2.5V)150mA + (4.2V x 150mA) PD(150mA) = 255.6mW PD(8.2%D/C) = %DC x PD(150mA) PD(8.2%D/C) = 0.082 x 255.6mW PD(8.2%D/C) = 21mW The power dissipation for 150mA load occurring for 8.2% of the duty cycle will be 21mW. Finally, the two power dissipation levels can summed to determine the total true power dissipation under the varied load. PD(total) = PD(100mA) + PD(150mA) PD(total) = 156.6mW + 21mW PD(total) = 177.6mW The maximum power dissipation for the AAT3216 operating at an ambient temperature of 85°C is 211mW. The device in this example will have a total power dissipation of 177.6mW.
