LTC1502-3.3 Single Cell to 3.3V Regulated Charge Pump DC/DC Converter FEATURES s s s s s s s s s s s DESCRIPTIO Input Voltage Range: 0.9V to 1.8V 0.9V Guaranteed Start-Up Voltage Regulated Output Voltage: 3.3V ± 4% Output Current: 10mA (VIN ≥ 1V) No Inductors Shutdown Disconnects Load from VIN Low Operating Current: 40µA Low Shutdown Current: 5µA Short-Circuit and Overtemperature Protected Application Circuit Fits in < 0.125in2 PCB Area Available in 8-Pin MSOP and SO Packages The LTC®1502-3.3 is a quadrupler charge pump DC/DC converter that produces a regulated 3.3V output from a single alkaline cell input. It requires only five small external capacitors—no inductors are required. Low supply current (40µA typical, 5µA in shutdown) and minimal external components make the LTC1502-3.
