200 mA LDO with 45 V input ceiling and military temp range
The Analog Devices LT3062MPMS8E#PBF is a single-output positive adjustable LDO regulator delivering 200 mA continuous output current from a 45 V maximum input rail. The 0.6 V minimum output voltage floors at the reference, and the output can be adjusted up to 40 V. Dropout voltage is 0.53 V max at 200 mA load, so the headroom between input and output must stay above 530 mV across the full load range to maintain regulation.
This is the spec that matters for powering sensitive analog front-ends from unregulated supplies. Quiescent current is 90 µA typical, rising to 10 mA maximum at the supply pin under heavy load. The 90 µA Iq floor keeps the regulator efficient in always-on systems where the load cycles between microamps and the full 200 mA. Built-in protection covers over-current, over-temperature, and reverse polarity on the input — the reverse polarity clamp prevents the output capacitor from back-driving the input when the supply collapses.

The soft-start control feature limits inrush current during startup, letting the output ramp up without triggering the over-current protection or pulling down the input rail.
