DESCRIPTION

The TK711xx is a low dropout, linear regulator housed in

a standard TO-92 package, rated at 500 mW. An internal

PNP transistor is used to achieve a low dropout voltage of

100 mV (typ.) at 30 mA load current. The TK711xx has a

low quiescent current of 130 µA (typ.) at no load. The low

quiescent current and dropout voltage make this part ideal

for battery powered applications.
