LOW DROPOUT VOLTAGE REGULATOR

FEATURES

n High Voltage Precision at ± 2.0% or ± 60 mV
n Very Low Quiescent Current
n Very Low Dropout Voltage
n Reverse Voltage Protection
n Miniature Package (SOT23-3)
n Short Circuit Protection
n High Ripple Rejection
n Can use Multilayer Ceramic Capacitors

DESCRIPTION

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.

APPLICATIONS

n Battery Powered Systems
n Cellular Telephones
n Pagers
n Personal Communications Equipment
n Portable Instrumentation
n Portable Consumer Equipment
n Radio Control Systems
n Toys
n Low Voltage Systems
