BLOCK DIAGRAM
TK111xxS
DESCRIPTION
The TK111xxS 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 85 mV (typ.) at 30 mA load current. The
TK111xxS has a very low quiescent current of 140
A
(typ.) at no load . The standby current is 100 nA maximum.
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 TK111xxS is available in a miniature SOT-23-5 surface
mount package.
