www.DataSheet4U.com DATA SHEET 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 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.
