The noise performance is achieved by means of an external bypass capacitor without sacrificing turn-on and turn-off speed critical to portable applications. Extremely stable and easy to use, these devices offer excellent PSRR and Line/Load regulation. Target applications include battery-powered equipment such as portable and wireless products. Regulators' ground current increases only slightly in dropout. Fast turn-on/turn-off enable control and an internal 301 pull down on output allows quick discharge of output even under no load conditions. Both LDOs are protected with current limit and thermal shutdown. Both LDOs are available in fixed & adjustable output voltage versions and come in an industry standard SOT-23 5-pin and small 2X3 pin DFN packages. For SC-70 00mA CMOS LDO, SP623 is available.

Exceeding the maximum allowable power dissipation will result in excessive die temperature and the regulator will go into thermal shutdown mode. eJA is 191°C/W for SOT-23-5, and is 59°C/W for the -pin DFN. A part mounted on a PC board will deliver improved thermal performance based upon copper surface area. Note 2: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 3: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Note 4: Dropout-voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at V differential. Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the ground pin current. Note 6: Output noise voltage is defined within a certain bandwidth, namely 0Hz < BW < 00kHz. An external bypass cap (0nF) from reference output (BYP pin) to ground significantly reduces noise at output. Note 7: Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load and line regulation effects. Specifications are for a 300mA load pulse at VIN = 6V for t = ms. Note 8: The wake-up time (TWU) is defined as the time it takes for the output to start rising after enable is brought high. Note 9: The total turn-on time is called the settling time (TS), which is defined as the condition when both the output and the bypass node are within 2% of their fully enabled values when released from shutdown. Note 10: For output voltage versions requiring VIN to be lower than V, timing (TON & TOFF) increases slightly.

Unlike bipolar regulators, the SP6203/6205 (CMOS LDO) supply current increases only slightly with load current. The SP6203/6205 contains an internal bandgap reference which is fed into the inverting input of the LDO-amplifier. The output voltage is then set by means of a resistor divider and compared to the bandgap reference voltage. The error LDO-amplifier drives the gate of a P-channel MOSFET pass device that has a RDS(ON) of 0.61 at 500mA producing a 300mV drop at the output. Furthermore, the SP6203/6205 has its own current limit circuitry (500mA/850mA) to ensure that the output current will not damage the device during output short, overload or start-up. Also, the SP6203/6205 includes thermal shutdown circuitry to turn off the device when the junction temperature exceeds 170°C and it remains off until the temperature drops by 12°C. An output capacitor is required between VOUT and GND to prevent oscillation. A 2.2µF output capacitor is recommended. Larger values make the chip more stable which means an improvement of the regulator’s transient response. Also, when operating from other sources than batteries, supply-noise rejection can be improved by increasing the value of the input and output capacitors and using passive filtering techniques. For a lower output current, a smaller output capacitance can be chosen. Finally, the output capacitor should have an effective series resistance (ESR) of 0.51 or less. Therefore, the use of good quality ceramic or tantalum capacitors is advised. Bypass Capacitor A bypass pin (BYP) is provided to decouple the bandgap reference. A 10nF external capacitor connected from BYP to GND reduces noise present on the internal reference, which in turn significantly reduces output noise and also improves power supply rejection. Note that the minimum value of COUT must be increased to maintain stability when the bypass capacitor is used because CBYP reduces the regulator phase margin. If output noise is not a concern, this input may be left unconnected. Larger capacitor values may be used to further improve power supply rejection, but result in a longer time period (slower turn on) to settle output voltage when power is initially applied. Enable/Shutdown Operation The SP6203/6205 is turned off by pulling the VEN pin below 0.4V and turned on by pulling it above 1.6V. If this enable/shutdown feature is not required, it should be tied directly to the input supply voltage to keep the regulator output on at all time. While in shutdown, VOUT quickly falls to zero (turn-off time is dependent on load conditions and output capacitance on VOUT) and power consumption drops nearly to zero. No Load Stability The SP6203/6205 will remain stable and in regulation with no external load (other than the internal voltage driver) unlike many other voltage regulators. This is especially important in CMOS RAM battery back-up applications. input Capacitor A small capacitor of 2.2µF is required from VIN to GND if a battery is used as the power source. Any good quality electrolytic, ceramic or tantalum capacitor may be used at the input.

TA is the ambient temperature. eJA is the junction-to-ambient thermal resistance for the regulator and is layout dependent. The SOT-23-5 package has a eJA of approximately 256°C/W for minimum PCB copper footprint area. This results in a maximum power dissipation of: PD(max) = [(125°C - 25°C)/(191°C/W)] = 523mW Turn On Time The turn on response is split up in two separate response categories: the wake up time (TWU) and the settlling time (TS). The wake up time is defined as the time it takes for the output to rise to 2% of its total value after being released from shutdown (EN > 0.4V). The settling time is defined as the condition where the output reaches 98% of its total value after being released from shutdown. The latter is also called the turn on time and is dependent on the output capacitor, a little bit on load and, if present, on a bypass capacitor. The actual power dissipation of the regulator circuit can be determined using one simple equation: PD = (VIN - VOUT) * IOUT + VIN * IGND t(s) = T(on) VENABLE To prevent the device from entering thermal shutdown. maximum power dissipation can not be exceeded. Substituting PD(max) for PD and solving for the operating conditions that are critical to the application will give the maximum operating conditions for the regulator circuit. For example, if we are operating the SP6203 3.0V at room temperature, with a minimum footprint layout and and output current of 300mA, the maximum input voltage can be determined, based on the equation below. Ground pin current can be taken from the electrical specifications table (0.23mA at 300mA). 390mW = (VIN-3.0V) * 300mA + VIN *0.23mA % 2% VOUT t(wu) Turn Off Time The turn off time is defined as the condition where the output voltage drops about 66% (e) of its total value. 5e to 7e is the constant where the output voltage drops nearly to zero. There will always be a small voltage drop in shutdown because of the switch unless we short-circuit it. The turn off time of the output voltage is dependent on load conditions, output capacitance on VOUT (time constant o = RLCL) and also on the difference in voltage between input and output. After calculations, we find that the maximum input voltage of a 3.0V application at 300mA of output current in a SOT-23-5 package is 4.7V. Thermal Considerations The SP6203/6205 is designed to provide 300/ 500 mA of continuous current in a tiny package. Maximum power dissipation can be calculated based on the output current and the voltage drop across the part. To determine the maximum power dissipation of the package, use the junction-to-ambient thermal resistance of the device and the following basic equation: So if the intend is to operate a 5V output version from a 6V supply at 300mA load and at a 25°C ambient temperature, then the actual total power dissipation will be: PD=([6V-5V]*[300mA])+(6V*0.23mA)=301.4mW This is well below the 523mW package maximum. Therefore, the regulator can be used.

For example, in a 5V input to 3.0V output application at an ambient temperature of 25°C and operating at the full 500mA (IGND = 0.355mA) load, the regulator is limited to a much lower load current, determined by the following equation: Layout Considerations The primary path of heat conduction out of the package is via the package leads. Therefore, careful considerations have to be taken into account: 1) Attaching the part to a larger copper footprint will enable better heat transfer from the device, especially on PCB’s where there are internal ground and power planes. 523mW = ( [5V-3V]*[ Iload(max)]) +(5V*0.350mA) After calculation, we find that in such an application (SP6205) the regulator is limited to 260.6mA. Doing the same calculations for the 300mA LDO (SP6203) will limit the regulator’s output current to 260.9mA. 2) Place the input, output and bypass capacitors close to the device for optimal transient response and device behavior. 3) Connect all ground connections directly to the ground plane. In case there’s no ground plane, connect to a common local ground point before connecting to board ground. Also, taking advantage of the very low dropout voltage characteristics of the SP6203/6205, power dissipation can be reduced by using the lowest possible input voltage to minimize the input-to-output drop. Such layouts will provide a much better thermal conductivity (lower eJA) for, a higher maximum allowable power dissipation limit. Adjustable Regulator Applications The SP6203/6205 can be adjusted to a specific output voltage by using two external resistors (see functional diagram). The resistors set the output voltage based on the following equation: VOUT = VREF *(R1/R2 + 1) Resistor values are not critical because ADJ (adjust) has a high input impedance, but for best performance use resistors of 470K1 or less. A bypass capacitor from ADJ to VOUT provides improved noise performance. Dual-Supply Operation When used in dual supply systems where the regulator load is returned to a negative supply, the output voltage must be diode clamped to ground.
