LTC3265 Low Power ±20V Power Supply from a Single-Ended 15V Input Supply

Low Power ±20V Power Supply from a Single-Ended 15V Input Supply

The LTC®3265 is a low noise dual polarity output power supply including a boost charge pump, an inverting charge pump and two low noise positive and negative LDO post regulators. The boost charge pump powers the positive LDO post regulator while the inverting charge pump powers the negative LDO regulator. Each LDO can provide up to 50mA of output current. The LDO output voltages can be adjusted using external resistor dividers.
