LTC3265EDHC#PBF

LTC3265 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 upto 50mA of output current. The LDO output voltages can be adjusted using external resistor dividers. The charge pumps employ low quiescent current Burst Mode operation or low noise constant frequency mode. It is used in application such as low noise bipolar/inverting supplies, industrial/instrumentation low noise bias generators etc.

• Input voltage range is 4.5V to 16V at (boost charge pump generates 2 VIN-P)
• Input voltage range is 4.5V to 32V at (inverting charge pump generates –VIN-N)
• Low noise positive LDO post regulator upto 50mA
• Low noise negative LDO post regulator upto 50mA
• 135µA quiescent current in Burst Mode® operation with both LDO regulators on
• Programmable oscillator frequency range is 50KHz to 500KHz
• Stable with ceramic capacitors
• Short-circuit/thermal protection
• Operating temperature is -40°C to 125°C
• Package style is 18-lead plastic DFN
