TK11547TL

VOLTAGE REGULATOR WITH ON/OFF SWITCH

DESCRIPTION

The TK115xx series devices are low power, linear regulators with electronic ON/OFF switches. Both active HIGH and active LOW control pins are provided.

An internal PNP pass-transistor is used in order to achieve low dropout voltage typically 200 mV at 80 mA load current. A base drive is available at pin 7 for connection of an external pass transistor should higher current up to 1 A or lower dropout voltage is required.
