DESCRIPTION
The TK113xxB is a low dropout linear regulator with a built-
in electronic switch. The device is in the “on” state when
the control pin is pulled to a low level. An external capacitor
can be connected to the noise bypass pin to lower the
output noise level to 30
µVrms.
An internal PNP pass transistor is used to achieve a low
dropout voltage of 80 mV (typ.) at 30 mA load current. The
TK113xxB has a very low quiescent current of 170
µA
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.
