FEATURES
DESCRIPTION
The TK112xxA is a low dropout linear regulator with a built-
in electronic switch. The internal 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 logic high level. An
external capacitor can be connected to the noise bypass
pin to lower the output noise level to 30 Vrms.
An internal PNP pass transistor is used to achieve a low
dropout voltage of 70 mV (typ.) at 30 mA load current. The
TK112xxA has a very low quiescent current of 180 A at no
load and 1 mA with a 30 mA load. The standby current is
typically 100 nA. The internal thermal shutdown circuitry
limits the junction temperature to below 150 C. The load
current is internally monitored and the device will shutdown
in the presence of a short circuit or overcurrent condition at
the output.
The TK112xxA is available in either 6 pin SOT-23L or 5 pin
SOT-89-5 surface mount packages.
