TK712xx
20P
LOW DROPOUT REGULATOR
FEATURES
■ Low Dropout Voltage
■ Low Quiescent Current
■ Very Stable Output
■ Low Noise (35 µVrms)
■ Miniature Package (SOT-25)
DESCRIPTION
TK712xx is a low dropout, linear regulator. Since a PNP
power transistor is used, dropout voltage is very low,
making it possible to maintain stable output voltage even
as the battery decreases. This allows longer battery life.
The TK712xx has a noise bypass pin available for noise
reduction.
The TK712xx is available in a miniature SOT-25 surface
mount package.
APPLICATIONS
■ Battery Powered Systems
■ Portable Consumer Equipment
■ Cordless Telephones
■ Personal Communications Equipment
■ Radio Control Systems
■ Toys
■ Low Voltage Systems
