BLOCK DIAGRAM
The TK73200 is a controller IC for an adjustable low
dropout voltage regulator. The TK73200 and the external
PNP power transistor provide adjustable output voltages
from 2 to 12 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.
