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
μ
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
μ
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.
The TK112xxB is available in either a 6-pin SOT-23L or a
5-pin SOT-89 surface mount package.
