Product details

What this LDO brings to a noise-sensitive rail

The Analog Devices LT3045MPDD#PBF is a single-output, positive adjustable LDO regulator delivering up to 500 mA. Its PSRR is 117 dB at 120 Hz rolling off to 53 dB at 10 MHz. Maximum dropout at full load is 0.45 V. Output is adjustable from 0 V to 15 V via external resistors.

Rated for the harsh edge

The 10-DFN (3x3 mm) exposed-pad package pulls heat into the PCB copper. Protection features include over-current, over-temperature, reverse polarity, and under-voltage lockout.

Frequently asked questions

Is LT3045MPDD#PBF RoHS compliant?

Yes, it is ROHS3 compliant.

What is the equivalent or replacement for LT3045MPDD#PBF?

The LT3045EMSE#PBF is a close functional equivalent with the same 500 mA output and PSRR, but in an MSOP-12 package and rated -40°C to 125°C. Verify the footprint and temperature requirements before substituting.

What is LT3045MPDD#PBF's listed PSRR?

PSRR is 117 dB at 120 Hz, rolling to 53 dB at 10 MHz — suitable for cleaning noise on sensitive analog and RF supply rails.
