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
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
TK113xxB 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 TK113xxB is available in either 6-pin SOT23L or 5-pin
SOT89 surface mount packages.

C.
Note 2: Refer to “Definition of Terms.”
Note 3: Ripple rejection and noise voltage are affected by the value and characteristics of the capacitor used.
Note 4: Output noise voltage can be reduced by connecting a capacitor to a noise pass terminal.
