The TK732xx is a controller IC for a low dropout voltage regulator. The TK732xx and the external PNP power transistor provide standard output voltages from 2 to 11 V and output current from 100 mA to 5 A. By utilizing an external PNP power transistor, low dropout voltage at high current can be readily achieved. The internal electronic switch can be controlled by TTL or CMOS logic levels. The device is in the “on” state when the control pin is pulled to a high logic level. A pin for a bypass capacitor, which connects to the internal circuitry, is provided to lower the overall output noise level. The current limit characteristics can be configured as continuous (constant current) or pulsed (cycling). An internal thermal shutdown circuit limits the junction temperatures to below 150 °C. In the “off” mode, the output of the regulator becomes a high impedance. This prevents the output capacitor from being rapidly discharged for backup to the load
