BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC2250 SERIES
LOW-SATURATED STABILIZED POWER SUPPLY WITH SYSTEM RESET PIN
DESCRIPTION
The µPC2250 series is a collection of low-saturated 4-pin stabilized power supplies with a pin that outputs a reset signal when a drop in the input voltage is detected. Because the reverse leakage current of these power supplies is about 1 µA even if a voltage is applied to the output pin when the input voltage is cut off, these power supplies are ideal for systems with on-board microprocessors requiring battery backup.
FEATURES
• • • • Low minimum voltage difference between input and output VDIF = 0.15 V TYP. (at IO = 40 mA) Outputs reset signal (active-low) when the input voltage or output voltage drops.
