Output voltage is adjustable using an external resistor divider (LTC1515) or programmable to either 3V/5V (LTC1515-3/5) or 3.3V/5V (LTC1515-3.3/5) using a logic pin. 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 power-on reset circuit forces the POR pin low on initial power-up. The POR output remains low until 200ms (typ) after VOUT is in regulation. The parts are short-circuit and overtemperature protected. Battery life is maximized by very low operating currents (ICC = 60µA typ, ICC < 1µA in shutdown). All three parts are available in an SO-8 package. , LTC and LT are registered trademarks of Linear Technology Corporation.
