LTC3265MPFE#TRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LTC3265MPFE#TRPBF is a low-noise dual polarity output power supply from Analog Devices Inc., designed to generate positive and negative rails from a single-ended input. It integrates a boost charge pump, an inverting charge pump, and two low-noise LDO post-regulators. The device accepts an input voltage range of 4.5V to 32V and provides fixed outputs at -Vin and +2Vin. It delivers up to 100mA of output current with a switching frequency adjustable between 50kHz and 500kHz. Packaged in a 20-TSSOP with exposed pad for surface mount installation, it operates within a temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix MPFE against official Analog Devices documentation to confirm military-grade qualification and environmental compliance. Ensure the TRPBF designation matches the required tape and reel packaging format for automated assembly processes. Cross-reference the full part number with manufacturer datasheets to validate pinout compatibility and thermal characteristics before integration into final designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single input rail must be converted into stable, low-noise positive and negative voltages. The integrated LDOs simplify design by reducing external component count compared to discrete solutions. Consider the 100mA current limit and the -Vin/+2Vin output topology to ensure it meets the specific voltage and load requirements of the target application circuit.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LTC3265 family of low-noise dual supply power management ICs. It shares core architecture with variants like the LTC3265EFE but differs in package type and qualification level. The series is engineered for applications demanding high PSRR and low ripple from compact charge pump topologies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LTC3265EFE#PBF offers identical electrical functionality in a tube package instead of tape and reel.
