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.
