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.
FEATURES
• Wide output voltage variable range Vo: 4.5 to 30 V, VDIF: 3 to 30 V
• Excellent load stability
0.02%
• Good ripple rejection ratio
0.003%/V
