BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC29M00 Series
THREE TERMINAL LOW DROPOUT
VOLTAGE REGULATOR
The µ PC29M00 series of low dropout
voltage three terminal positive regulators is constructed with PNP output transistor. The µ PC29M00 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 µ PC29M00 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 (µ PC24M00A series).
FEATURES
Output current in excess of 0.5 A Low dropout
voltage VDIF = 0.5 V TYP. (at I O = 0.5 A) On-chip overcurrent and thermal protection circuit On-chip output transistor safe area protection circuit
