BIPOLAR ANALOG INTEGRATED CIRCUIT

µ PC29xx Series

THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR

The

µPC29xx series of low dropout voltage three terminal positive regulators is constructed with PNP output

transistor. The

µPC29xx series feature the ability to source 1 A of output current with a low dropout voltage of typically

0.7 V.

The power dissipation of the

µPC29xx series can be drastically reduced compared with the conventional three

terminal positive voltage regulators that is constructed with NPN output transistor. Also, this series corresponds to

the low voltage output (3.0 V, 3.3 V) which is not in the conventional low dropout regulators (

µPC24xxA series).
