The 1.5V dropout at full load means you need at least 6.5V on the input to hold regulation — typical for high-voltage LDOs with this headroom. Quiescent current sits at 140 µA, which keeps the always-on or standby draw manageable in battery-backed designs. The -40°C to 125°C operating range covers under-hood and factory-floor environments. ## PSRR and protection set Power-supply rejection ratio is 54 dB at 100 Hz — enough to clean up line-frequency ripple from a rectified AC source or a switching pre-regulator for sensitive analog loads. The part packs Enable, Hold, Reset, and Watchdog control features, plus over-temperature, reverse-polarity, and short-circuit protection. That watchdog is unusual for a simple LDO and suggests it was designed for safety-critical or supervised-rail applications where a missing clock triggers a reset. ## Package and mounting Housed in an 8-SOIC (0.154\", 3.90mm width) — surface-mount, standard footprint, easy to hand-rework with hot air or a soldering iron. MSL level is not in the record, but an 8-SOIC typically runs MSL 1 or 2; if the bag seal is broken, a short bake before reflow is cheap insurance. The 150mA output means the package handles the dissipation without a thermal pad — just normal copper pour on the PCB. ## Lifecycle and sourcing Listed as Active and ROHS3 compliant. No official second source or pin-compatible alternate is documented in the ledger, so dual-sourcing would require a parametric search for a 65V-capable, 5V fixed LDO in 8-SOIC.","metaTitle":"MAX5023LASA+ 5V 150mA LDO, 65V Input, 8-SOIC","metaDescription":"MAX5023LASA+ 5V fixed-output LDO, 150mA, 65V max input, 1.5V dropout at full load, -40°C to 125°C, 8-SOIC.
