It integrates a watchdog timer, reset output, and hold input alongside the usual enable pin, so it can supervise a microcontroller's health while powering it from a single regulator. ## PSRR and quiescent current — the noise and standby trade-off PSRR is 54 dB at 100 Hz — this is the ripple-rejection figure at the fundamental of a full-wave rectified mains supply. For a 12 V battery-fed system with a 100 Hz ripple component, the output ripple is attenuated by a factor of roughly 500, so a 100 mV input ripple becomes 0.2 mV at the output. Quiescent current is 140 µA typical — low enough for an always-on rail in a vehicle body controller or an industrial sensor node that stays powered during ignition-off periods, but not in the sub-10 µA range needed for coin-cell battery life. ## Dropout headroom and protection for a 12 V / 24 V system Maximum dropout voltage is 1.5 V at 150 mA load. For a 5 V output, the input must stay above 6.5 V across the full load range to maintain regulation — a 12 V nominal battery that dips to 8 V during cranking still holds margin. Built-in protection covers over-temperature shutdown, reverse polarity on the input, and output short-circuit current limiting. These are the three failure modes that kill an unprotected LDO in an automotive or industrial power rail — the part survives a miswired battery or a dead short on the output without external clamp diodes. ## Active production and compliance status Sourced through authorized and independent distribution channels; lead time and pricing confirmed at RFQ against the BOM quantity.","metaTitle":"MAX5023LASA+T 5V 150mA LDO, 65V Input, 8-SOIC","metaDescription":"Analog Devices MAX5023LASA+T: 5V fixed-output LDO, 150mA, 65V max input, 54dB PSRR at 100Hz, -40 to +125°C, 8-SOIC.
