UPC2933A Datasheet, PDF (1/16 Pages) NEC – THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR

DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC2933A, 2905A
THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR
DESCRIPTION
The µPC2933A, 2905A of low dropout voltage three terminal positive regulators is constructed with PNP output
transistor. The µPC2933A, 2905A 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 µPC2933A, 2905A 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).
FEATURES
• Output current in excess of 1.0 A
• Low dropout voltage VDIF = 0.7 V TYP. (at IO = 1 A)
• On-chip overcurrent and thermal protection circuit
• On-chip output transistor safe area protection circuit
