UPC2260 Datasheet Low Dropout Voltage Regulator

Manufacturer: NEC (now Renesas Electronics)

Overview: .. DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µ PC2260 LOW DROPOUT VOLTAGE REGULATOR WITH SYSTEM RESET.

General Description

The µ PC2260 is a 500 mA maximum output current low dropout voltage regulator with a reset pin that outputs a reset signal when a drop in the output voltage is detected, and a reset signal output timing adjustment pin.

The output voltage is 5 V, and the minimum voltage difference between input and output is extremely low, making this product ideal for use in the power supply circuits of systems with built-in battery-driven microprocessors.

Because the reverse leakage current of this power supply is about 10 µ A even if a voltage is applied to the output pin when the input voltage is cut off, a reverse protection diode is not necessary even in systems requiring battery backup.

Key Features

  • Outputs reset signal (active low) when the output voltage drops.
  • Power on reset constant can be set by attaching a single capacitor.
  • Low minimum voltage difference between input and output VDIF = 0.5 V TYP . (when IO = 500 mA).
  • Low reverse current leakage during back up IOLK = 10 µ A MAX. (at VIN = 0 V, VO = 5 V, 0°C ≤ TJ ≤ 125°C) PIN.
