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
μ
A (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.
