Output voltage is fixed at either 3.3V (LTC1514-3.3) or 5V (LTC1514-5) by an internal resistor divider. A unique architecture allows the parts to accommodate a wide input voltage range (2V to 10V) while maintaining ±4% regulation. Additional circuitry prevents excessive inrush current and output voltage ripple when large VIN to VOUT differentials are present. An internal uncommitted comparator is kept active in shutdown. The comparator has an open-drain output for flexible interfacing. The parts are short-circuit and overtemperature protected. Battery life is maximized by very low operating currents (I CC = 60μA typ, 10μA in shutdown). Both parts are available in an SO-8 package.
