BIPOLAR ANALOG INTEGRATED CIRCUIT
µ PC2260
LOW DROPOUT VOLTAGE REGULATOR WITH SYSTEM RESET PIN
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.
FEATURES
PIN CONFIGURATION (Marking Side)
• Outputs reset signal (active low) when the output voltage drops.
5-pin plastic V-DIP (V)
• Power on reset constant can be set by attaching a single capacitor.
µ PC2260V
• 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)
