TC1016 80 mA, Tiny CMOS LDO With Shutdown Features General Description • Space-Saving 5-Pin SC-70 and SOT-23 Packages • Extremely Low Operating Current for Longer Battery Life: 53 µA (typ.) • Very Low Dropout Voltage • Rated 80 mA Output Current • Requires only 1 µF Ceramic Output Capacitance • High Output Voltage Accuracy: ±0.5% (typ.) • 10 µsec (typ.) Wake-Up Time from SHDN • Power-Saving Shutdown Mode: 0.05 µA(typ.) • Overcurrent and Overtemperature Protection • Pin Compatible Upgrade for Bipolar Regulators The TC1016 is a high-accuracy (typically ±0.5%), CMOS upgrade for bipolar low dropout regulators (LDOs). The TC1016 is offered in both the SC-70 and SOT-23 packages. The SC-70 package represents a 50% footprint reduction versus the popular SOT-23 package. Applications • • • • • • Cellular/GSM/PHS Phones Battery-operated Systems Portable Computers Medical Instruments Electronic Games Pagers Developed specifically for battery-powered systems, the device’s CMOS construction consumes only 53 µA typical supply current over the entire 80 mA operating load range. This can be as much as 60 times less than the quiescent operating current consumed by bipolar LDOs. With small-space requirements and cost in mind, the TC1016 was developed to be stable over the entire input voltage and output current operating range using low value (1 µF ceramic), low Equivalent Series Resistance (ESR) output capacitors. Additional integrated features (such as shutdown, overcurrent and overtemperature protection) further reduce board space and cost of the entire voltage-regulating application. Key performance parameters for the TC1016 are low drop out voltage (150 mV (typ.) at 80 mA output current), low supply current while shutdown (0.05 µA typical) and fast stable response to sudden input voltage and load changes.

VR is the regulator voltage setting. For example: VR = 1.8V, 2.7V, 2.8V, 3.0V. 3: TCV 4: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the Thermal Regulation specification. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value at a 1V differential. Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to Ilmax at VIN = 6V for t = 10 msec. The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable juction temperature and the thermal resistance from junction-to-air (i.e. TA, TJ, θJA). Exceeding the maximum allowable power dissipation causes the device to initiate thermal shutdown.

The regulator enters shutdown when a logic-low is applied to this input. During shutdown, the output voltage falls to zero and the supply current is reduced to 0.05 µA (typ.) 3.2 Ground Terminal (GND) For best performance, it is recommended that the ground pin be tied to a ground plane. 3.3 3.4 Unregulated Supply Input (VIN) The minimum VIN has to meet two conditions in order to ensure that the output maintains regulation: VIN ≥ 2.7V and VIN ≥ [(VR + 2.5%) + VDROPOUT]. The maximum VIN should be less than or equal to 6V. Power dissipation may limit VIN to a lower potential in order to maintain a junction temperature below 125°C. Refer to Section 5.0 “Thermal Considerations”, for determining junction temperature. It is recommended that VIN be bypassed to GND with a ceramic capacitor. Regulated Voltage Output (VOUT) Bypass the regulated voltage output to GND with a minimum capacitance of 1 µF. A ceramic bypass capacitor is recommended for best performance. DS21666B-page 8 © 2005 Microchip Technology Inc. TC1016 4.0 DETAILED DESCRIPTION MOSFET is turned on. If the internal power dissipation is still high enough for the junction to rise to 160°C, it will again shut off and cool. The maximum operating junction temperature of the device is 125°C. Steadystate operation at or near the 160°C overtemperature point can lead to permanent damage of the device. The TC1016 is a precision, fixed-output, linear voltage regulator. The internal linear pass element is a Pchannel MOSFET. As with all P-channel CMOS LDOs, there is a body drain diode, with the cathode connected to VIN and the anode connected to VOUT (Figure 4-1). The output voltage (VOUT) remains stable over the entire input operating voltage range (2.7V to 6.0V), as well as the entire load range (0 mA to 80 mA). The output voltage is sensed through an internal resistor divider and compared with a precision internal voltage reference. Several fixed-output voltages are available by changing the value of the internal resistor divider. As shown in Figure 4-1, the output voltage of the LDO is sensed and divided down internally to reduce external component count. The internal error amplifier has a fixed, band gap reference on the inverting input, with the sensed output voltage on the non-inverting input. The error amplifier output will pull the gate voltage down until the inputs of the error amplifier are equal in order to regulate the output voltage. Figure 4-2 shows a typical application circuit. The regulator is enabled anytime the shutdown input pin is at or above VIH, and shutdown (disabled) anytime the shutdown input pin is below VIL. For applications where the SHDN feature is not used, tie the SHDN pin directly to the input supply voltage source. While in shutdown, the supply current decreases to 0.05 µA (typ.) and the P-channel MOSFET is turned off. By sensing the current in the P-channel MOSFET, the maximum current delivered to the load is limited to a typical value of 120 mA, preventing excessive current from damaging the Printed Circuit Board (PCB) in the event of a shorted or faulted load. An internal thermal sensing device is used to monitor the junction temperature of the LDO. When the sensed temperature is over the set threshold of 160°C (typ.), the P-channel MOSFET is turned off. When the MOSFET is off, the power dissipation internal to the device is almost zero. The device cools until the junction temperature is approximately 150°C and the As shown in Figure 4-2, batteries have internal source impedance. An input capacitor in used to lower the input impedance of the LDO. In some applications, high input impedance can cause the LDO to become unstable. Adding more input capacitance can compensate for this. 1 SHDN VIN 5 Current Limit 2 NC VIN SHDN VREF Control EA + Body Diode Error Amp 3 GND VOUT 4 Over Temp.

DS21666B-page 9 TC1016 4.1 Input Capacitor 4.3 Low input source impedance is necessary for the LDO to operate properly. When operating from batteries, or in applications with long lead length (> 10") between the input source and the LDO, some input capacitance is required. A minimum of 0.1 µF is recommended for most applications and the capacitor should be placed as close to the input of the LDO as is practical. Larger input capacitors will help reduce the input impedance and further reduce any high-frequency noise on the input and output of the LDO. 4.2 Output Capacitor A minimum output capacitance of 1 µF for the TC1016 is required for stability. The ESR requirements on the output capacitor are between 0 and 2 ohms. The output capacitor should be located as close to the LDO output as is practical. Ceramic materials X7R and X5R have low temperature coefficients and are well within the acceptable ESR range required. A typical 1 µF X5R 0805 capacitor has an ESR of 50 milli-ohms. Larger output capacitors can be used with the TC1016 to improve dynamic behavior and input ripple rejection performance. Ceramic, aluminum electrolytic or tantalum capacitor types can be used. Since many aluminum electrolytic capacitors freeze at approximately –30°C, ceramic or solid tantalums are recommended for applications operating below –25°C. When operating from sources other than batteries, supply noise rejection and transient response can be improved by increasing the value of the input and output capacitors, and by employing passive filtering techniques. Turn-On Response The turn on response is defined as two separate response categories, Wake-up Time (tWK) and Settling Time (tS). The TC1016 has a fast tWK (10 µsec, typ.) when released from shutdown. Figure 4-3 provides the TC1016’s tWK. The tWK is defined as the time it takes for the output to rise to 2% of the VOUT value after being released from shutdown. The total turn-on response is defined as the tS (see Figure 4-3). The tS (inclusive with tWK) is defined as the condition when the output is within 98% of its fully enabled value (42 µsec, typ.) when released from shutdown. The settling time of the output voltage is dependent on load conditions and output capacitance on VOUT (RC response). Table 4-1 demonstrates the typical turn-on response timing for different input voltage power-up frequencies: VOUT = 2.8V, VIN = 5.0V, IOUT = 60 mA and COUT = 1 µF.

TC1016 5.0 THERMAL CONSIDERATIONS 5.1 Thermal Shutdown Integrated thermal-protection circuitry shuts the regulator off when die temperature exceeds approximately 160°C. The regulator remains off until the die temperature drops to approximately 150°C. Given the following example: VOUT = 2.8V ±2.5% ILOAD = 60 mA (output current) Find: Power Dissipation Internal power dissipation: P DMAX = ( V IN_MAX – V OUT_MIN ) × ILOAD The TC1016 is available in the SC-70 package. The thermal resistance for the SC-70 package is approximately 450°C/W when the copper area used in the PCB layout is similar to the JEDEC J51-7 high thermal conductivity or Semi G42-88 standards. For applications with larger or thicker copper areas, the thermal resistance can be lowered. See AN792 “A Method to Determine How Much Power a SOT23 Can Dissipate in an Application” (DS00792), for a method to determine the thermal resistance for a particular application. The TC1016 power dissipation capability is dependant upon several variables: input voltage, output voltage, load current, ambient temperature and maximum junction temperature. The absolute maximum steadystate junction temperature is rated at 125°C. The power dissipation within the device is equal to: EQUATION 5-1: PD = ( VIN – V OUT ) × I LOAD + V IN × I GND The VIN x IGND term is typically very small when compared to the (VIN-VOUT) x ILOAD term simplifying the power dissipation within the LDO to be: EQUATION 5-2: = ( 4.1V – 2.8 × ( 0.975 ) ) × 60mA = 82.2mW 2. dissipation EQUATION 5-3: ( T J_MAX – T A_MAX ) P DMAX = ------------------------------------------------RθJA Junction temperature: T J_MAX = = = = 3.

The absolute maximum power dissipation is 155 mW when given a maximum ambient temperature of 55°C. Input voltage, output voltage or load current limits can also be determined by substituting known values in Equation 5-2 and Equation 5-3. 5.3 PD = ( VIN – VOUT ) × I LOAD To determine the maximum power capability, the following equation is used: = 3.0V to 4.1V TAMAX = 55°C (max. ambient temp.) 1. 5.2 VIN Layout Considerations The primary path for heat conduction out of the SC-70 package is through the package leads. Using heavy, wide traces at the pads of the device will facilitate the removal of heat within the package, thus lowering the thermal resistance RθJA. By lowering the thermal resistance, the maximum internal power dissipation capability of the package is increased.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
