DATA SHEET 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). FEATURES • Output current in excess of 1.0 A • Low dropout voltage VDIF = 0.7 V TYP. (IO = 1 A) • On-chip over-current and thermal protection circuit • On-chip output transistor safe operating area protection circuit PIN CONFIGURATIONS (Marking Side) µ PC29xxHF Series: Isolated TO-220 (MP-45G) µ PC29xxHB Series: SC-64 (MP-3) µ PC29xxT Series: SC-63 (MP-3Z) 4 1 2 3 1: INPUT 2: GND 3: OUTPUT 1 2 3 4 1: INPUT Note1 2: GND 3: OUTPUT 4: GND (Fin) 1 2 3 1: INPUT 2: GNDNote2 3: OUTPUT 4: GND (Fin) Notes 1.
