FEATURES
DESCRIPTION
The TK112xxB 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 80 mV (typ.) at 30 mA load current. The
TK112xxB has a very low quiescent current of 170 A at
no load and 1 mA with a 30 mA load. The standby current
is typically 100 nA. The internal thermal shut down circuitry
limits the junction temperature to below 150 C. The load
current is internally monitored and the device will shut
down in the presence of a short circuit or overcurrent
condition at the output.
