What are the key features of LT3094HDD#PBF?
- Ultralow output noise and ultrahigh PSRR negative linear regulator ideal for noise-sensitive RF and analog signal chains
- 500 mA output current with 235 mV nominal dropout voltage and up to 20 V input-output differential range
- Compact 12-pin DFN (S-PDSO-N12) package supporting parallel operation for increased current or PolyPhase configurations
What is LT3094HDD#PBF used for?
The LT3094HDD#PBF is designed for noise-sensitive analog and RF applications such as VCO power supplies, ADC reference rails, and low-noise amplifier bias circuits where an ultralow-noise negative voltage rail is required. Its high PSRR across a wide frequency range rejects power supply disturbances that would otherwise degrade phase noise or dynamic range. The adjustable negative output and 500 mA current capability also suit laboratory bench supplies and optical transceiver bias networks requiring clean negative rails.

Frequently Asked Questions
What output current and dropout voltage does the LT3094HDD#PBF deliver for negative LDO applications?
The LT3094HDD#PBF provides up to 500 mA of output current with a nominal dropout voltage of only 235 mV and a maximum of 410 mV. This low dropout over the full 20 V input-output differential range makes it suitable for powering noise-sensitive circuits from negative supply rails without wasting significant headroom.
Which RF or precision analog signal-chain designs benefit most from the LT3094HDD#PBF's ultralow noise?
VCO bias supplies, low-noise amplifier drain rails, ADC reference buffers, and RF front-end negative supply rails all benefit from the LT3094's ultralow output noise spectral density and ultrahigh PSRR. In phase-locked loops, reducing regulator noise by even a few nV/√Hz can measurably improve phase noise by 3 dB to 6 dB, a critical advantage for communications and test equipment designs.
Can multiple LT3094HDD#PBF devices be paralleled to supply more than 500 mA?
Yes. Analog Devices designed the LT3094 for parallel operation; connecting the SET pins together allows two or more 500 mA devices to share current in a PolyPhase configuration, effectively doubling or tripling the available output current while maintaining the ultralow noise and high PSRR characteristics. Each 12-pin DFN device contributes 500 mA, so two paralleled units can supply 1 A with the same noise floor as a single device.
