DESCRIPTION

The TK715xx is a low dropout linear regulator housed in a

small SOT-23-3 package, rated at 350 mW. An internal

PNP transistor is used to achieve a low dropout voltage of

105 mV (typ.) at 50 mA load current. This device offers high

precision output voltage of

2.0 % or

60 mV. The

TK715xx has a very low quiescent current of 25

µA

(typ.)

at no load. The low quiescent current and dropout voltage

make this part ideal for battery powered applications. The

internal reverse bias protection eliminates the requirement

for a reverse voltage protection diode, saving cost and

board space. The high 64 dB ripple rejection and low noise

provide enhanced performance for critical applications.
