DESCRIPTION

The

µPC29M33A, µPC29M05A of low dropout voltage three terminal positive regulators is constructed with PNP output

transistor. The

µPC29M33A, µPC29M05A feature the ability to source 0.5 A of output current with a low dropout voltage

of typically 0.5 V.

The power dissipation of the

µPC29M33A, µPC29M05A 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 (

µPC24M00A series).
