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 input voltage is cut off, these power supplies are ideal for .
