Dual 2.85 V LDO with 62 dB PSRR for analog supply rails
The MAX8531EBTJJ-T is a dual-output low-dropout linear regulator from Maxim Integrated, delivering a fixed 2.85 V on both channels — one rated 200 mA, the other 150 mA. The 62 dB PSRR at 100 Hz makes it a candidate for powering noise-sensitive analog blocks such as ADC reference buffers or audio codecs where upstream switching noise needs suppression before the rail reaches the load.
Dropout and quiescent budget for tight input margins
Maximum dropout is 200 mV at 100 mA on each output, meaning the input rail must stay at least 200 mV above 2.85 V across the full load range to maintain regulation. The 220 µA quiescent current covers both channels — relevant for always-on or battery-backed rails where standing current directly affects standby time.
Package, protection, and temperature grade
Housed in a 6-WFBGA WLBGA (6-WLP supplier device package), the part is surface-mount only. It includes enable and reset control features, plus over-current, over-temperature, and short-circuit protection.
