BIPOLAR ANALOG INTEGRATED CIRCUT

µPC305

POSITIVE VOLTAGE STABILIZED POWER SUPPLY

DESCRIPTION

The µPC305 is a high-performance stabilized power supply that can supply a constant voltage in a wide

temperature range even if the input voltage or load voltage fluctuates, by integrating a high-gain error amplifier and a

temperature-compensating constant-voltage diode on a single chip.
