LOW DROPOUT VOLTAGE REGULATOR

The TK715xx is a low dropout linear regulator housed in a

small SOT23-3 package, rated at 400 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 60 dB ripple rejection and low noise

provide enhanced performance for critical applications.
