The LTC3260EDE#PBF is a low noise dual polarity output power supply inverting Charge Pump with both positive and negative LDO regulators. The charge pump operates over a wide 4.5 to 32V input range and can deliver up to 100mA of output current. Each LDO regulator can provide up to 50mA of output current. The negative LDO post regulator is powered from the charge pump output. The LDO output voltages can be adjusted using external resistor dividers. The charge pump employs either low quiescent current burst mode operation or low noise constant frequency mode. In burst mode operation the charge pump VOUT regulates to -0.94 • VIN and the LTC3260 draws only 100µA of quiescent current with both LDO regulators on. In constant frequency mode the charge pump produces an output equal to -VIN and operates at a fixed 500kHz or to a programmed value between 50kHz to 500kHz using an external resistor.
● Inverting charge pump generates -VIN
● Stable with ceramic capacitors
● Short-circuit/thermal protection
