Its 65V maximum input rating makes it a natural fit for 24V and 48V industrial rails where a downstream 5V logic or sensor supply is needed without a separate DC-DC stage. The part integrates Enable, Hold, Reset, and Watchdog control features — the watchdog alone saves an external supervisor IC in applications where the microcontroller must be monitored for lock-up. ## Dropout, quiescent current, and protection Quiescent current is 140 µA typical, low enough to keep the regulator alive on a battery-backed rail without draining the reserve during standby. Protection covers over-temperature, reverse polarity, and short-circuit — the reverse-polarity clamp is unusual in a linear regulator and saves an external series diode when the input could be mis-wired. ## PSRR and noise rejection in the audio band PSRR is specified at 54dB at 100Hz, meaning ripple on the input at mains frequency and its harmonics is attenuated by a factor of roughly 500 before reaching the output — relevant when the regulator is powered from a rectified AC source or a switching pre-regulator with 100/120Hz ripple.","metaTitle":"MAX5023MASA+ Linear Regulator, 5V Fixed, 150mA, 8-SOIC","metaDescription":"Analog Devices MAX5023MASA+ high-voltage LDO: 65V input max, 5V fixed output, 150mA, PSRR 54dB at 100Hz, -40°C to 125°C.
