UPC2255 (UPC2250 Series) Low Staturated Stabilized Power Supply with System Reset Pin

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 i.

UPC2255 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 curre
