Description

The µPC2900 series of low dropout voltage three terminal positive regulators is constructed with PNP output transistor.  The µPC2900 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 µPC2900 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 V, 3.3 V) which is not in the conventional low dropout regulators (µPC2400A series).
