DESCRIPTION  
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(constantcurrent)orpulsed(cycling).Aninternal  
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.
