It operates from a 16 V maximum input and delivers 45 dB of PSRR at 1 kHz — enough rejection to keep switching-regulator ripple off a precision ADC or op-amp supply. ## Dropout, quiescent current, and protection Maximum dropout voltage is 0.58 V at 150 mA load — the input rail must stay at least that far above 1.8 V across the full load range to maintain regulation. Quiescent current is 95 µA typical, rising to 2.5 mA max under supply — a reasonable idle draw for a fixed-output LDO that stays enabled continuously. Built-in protection covers over-current, over-temperature, and short-circuit events, so the part survives a faulted output without external clamp diodes. ## Active production, RoHS3, and supply posture RoHS3 compliant (2011/65/EU + 2015/863) with no exemption — suitable for EU-market assemblies without a RoHS waiver.","metaTitle":"LP2985AIM5-1.8/NOPB LDO, 150mA, 1.8V fixed, SOT-23-5","metaDescription":"Texas Instruments LP2985AIM5-1.8/NOPB LDO, 150mA, 1.8V fixed output, 45dB PSRR at 1kHz, SOT-23-5.
