UPC29M33A Datasheet, PDF (1/16 Pages) NEC – THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR

DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC29M33A,µPC29M05A
THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR
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).
FEATURES
• Output current in excess of 0.5 A
• Low dropout voltage VDIF = 0.5 V TYP. (at IO = 0.5 A)
• On-chip overcurrent and thermal protection circuit
• On-chip output transistor safe area protection circuit
