FEATURES

DESCRIPTION

The TK112XX is a low power, linear regulator with a built-

in electronic switch. The internal electronic 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 high logic

level. A pin for a bypass capacitor is provided, which

connects to the internal circuitry, to lower the overall output

noise level.

An internal PNP pass-transistor is used in order to achieve

low dropout voltage (typically 100 mV at 30 mA load

current). The device has very low quiescent current (180

The quiescent current is typically 2.5 mA at 60 mA load.

When the device is in standby mode (V

quiescent current is typically 100 nA. An internal thermal

shutdown circuit 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 at the

output.
