μPC2900 Series

THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR

The μPC2900 series of low dropout voltage three terminal positive regulators is constructed with PNP output transistor. The μPC2900 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 μPC2900 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 (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

Note TC = 25 °C, Internally limited

When operating junction temperature rises up to 150 °C, the internal circuit shutdown output voltage.

Caution Exposure to Absolute Maximum Ratings for extended periods may affect device reliability; exceeding the ratings could cause permanent damage. The parameters apply independently. The device should be operated within the limits specified under DC and AC Characteristics.

CIN	+	D2
	COUT

CIN : More than 0.1 μF. Required if regulator is located an appreciable distance from power supply filter. You must use to prevent from the parasitic oscillation.

COUT : More than 47 μF. You must use the Low-impedance-type (low ESR) capacitor. D1 : Need for VO > VIN

D2 : Need a shottky barrier diode for VO < GND.
