UPC2255 Datasheet (upc2250 Series) Low Staturated Stabilized Power Supply With System Reset Pin

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET SHEET DATA BIPOLAR ANALOG INTEGRATED CIRCUIT µPC2250 SERIES LOW-SATURATED STABILIZED POWER SUPPLY WITH SYSTEM RESET.

General 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.

Key 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. Low reverse leakage current during back up IOLK = 1 µA TYP. Low circuit operating current under no load IBIAS = 1.3 mA TYP. PIN.
