General Description
The APL5151/2/3/4 is micropower, low noise, low dropout linear regulator. Operate from 3V to 6V input voltage and deliver up to 150mA. Typical output noise is just 60uVRMS with the addition of an external 0.33uF bypass capacitor in BP pin and typical dropout voltage is only 220mV at 150mA loading. Designed for use in battery-powered system, the low 50uA quiescent current makes it an ideal choice. Design with an internal P-channel MOSFET pass transistor, the APL5151/2/ 3/4 maintains a low supply current, independent of the load current and dropout voltage. Other features include reverse current protection, thermal-shutdown protection, current limit protection to ensure specified output current and controlled short-circuit current. The APL5151/2/3/4 regulators come in a miniature SOT23-5 package.

APL5151/2/3/4
Application Information
Capacitor Selection and Regulator Stability
The APL5151/2/3/4 use at least a 1uF capacitor on the input, and this capacitor can be Aluminum, Tantalum or Ceramic capacitor. The input capacitor with larger value and lower ESR provides better PSRR and line-transient response. The output capacitor also can use Aluminum, Tantalum or Ceramic capacitor, and a minimum value of 1uF and ESR above 0.06 is recommended. The curve of the stable region in typical characteristics shows the appropriate output capacitor ESR for different load current stable operation. A larger output capacitor can reduce noise and improve load-transient response, stability, and PSRR. Note that some ceramic dielectrics exhibit large capacitance and ESR variation with temperature. When using this capacitor, a minimum 2.2uF or more may be required to ensure the stability at low temperature operation. Use a bypass capacitor at BP pin for low output nvise. Increasing the capacitance will slightly decrease the output noise, but increase the start-up time. (See Shutdown Exit Delay and Output Noise v s. B ypass Capaci t or gra ph i n t he t yp i cal characteristics)
Input-Output (Dropout)Voltage
The minimum input-output voltage difference (dropout) determines the lowest usable supply voltage. In battery-powered systems, this will determine the useful end-of-life battery voltage. Because the APL5151/2/ 3/4 use a p-channel MOSFET pass transistor, the dropout voltage is a function of drain-to-source on-resistance (RDS(ON)) multiplied by the load current.
Reverse Current Protection
The APL5151/2/3/4 have an internal reverse protection, it does not need an external schottky diode to connect the regulator input and output. If the output voltage is forced above the input voltage by more than 11mV, the IC will be shutdown and the ground pin current is below 0.1uA.
Current Limit
The APL5151/2/3/4 have a current limit protection. The ouptut voltage will drop close to zero volt, when load current reaches the limit, and then the load current will be limited at 50mA after output voltage is below 0. 7V. When the load current back to the value where limiting started, the output voltage and current will return to normal value. When output is shorted to ground, the APL5151/2/3/4 will keep short circuit current at 150mA .
Load-Transient Considerations
The APL5151/2/3/4 load-transient response graphs in typical characteristics show the transient response. A step change in the load current from 1mA to 50mA at 1us will cause a 60mV transient spike. Larger output capacitor and lower ESR can reduce transient spike.

APL5151/2/3/4
Thermal Protection
Thermal protection limits total power dissipation in the device. When the junction temperature exceeds TJ=+150J, the thermal sensor generates a logic signal to turn off the pass transistor and allows IC to cool. When the IC' junction temperature is down by s 10J, the thermal sensor will turn the pass transistor on again, resulting in a pulsed output during continuous thermal protection. Thermal protection is designed to protect the APL5151/2/3/4 in the event of fault conditions. For continuous operation, do not exceed the absolute maximum junction temperature of TJ=+150J.
Operating Region and Power Dissipation
The thermal resistance of the case to circuit board, and the rate of air flow all control the APL5151/2/3/4' s maximum power dissipation. The power dissipation across the device is PD = IOUT (VIN-VOUT) and the maximum power dissipation is: PDMAX = (TJ-T A) / (c JC + c CA) where TJ-TA is the temperature difference between the junction and ambient air, c JC is the thermal resistance of the package, and c CA is the thermal resistance through the printed circuit board, copper traces, and other materials to the ambient air. The GND pin of the APL5151/2/3/4 provide an electrical connection to ground and channeling heat away. If power dissipation is large, connect the GND pin to ground using a large pad or ground plane, can improve the problem of over heat of IC.
