BIPOLAR ANALOG INTEGRATED CIRCUIT
µ PC29Mxx Series
THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR
The µPC29Mxx series of low dropout voltage three terminal positive regulators is constructed with PNP output
transistor. The µPC29Mxx series 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 µPC29Mxx 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 (µPC24MxxA series).
