The key fit parameter is the 0.165 V max dropout at full load — the input rail must stay at least 165 mV above 2.5 V across the load range, or the output falls out of regulation. For a 3.3 V bus feeding this LDO, the margin is about 0.635 V, which covers brownout dips down to roughly 2.7 V before dropout becomes a concern. Quiescent current is 180 µA typical, with a maximum supply current of 100 µA — the difference suggests the internal bias draws roughly 80 µA, and the remaining 100 µA is the output stage overhead. This Iq is moderate for a 150 mA LDO; it is not an ultralow-power part for always-on battery nodes, but it is reasonable for a regulated rail in a sensor module or industrial control board where the load is intermittent. ## PSRR at 10 kHz — what 63 dB actually buys you The 63 dB PSRR at 10 kHz means the LDO attenuates ripple on the input by a factor of roughly 1400 at that frequency. If the input has 100 mVpp switching noise from a nearby buck converter, the output sees about 70 µVpp — clean enough for a 10-bit ADC reference or a sensitive analog front-end. PSRR rolls off above 10 kHz, so upstream filtering ahead of the LDO is still advisable if the switching noise is above 100 kHz. ## Protection set and temperature grade The MAX8867EUK25 includes over-current, over-temperature, reverse polarity, and short-circuit protection — a solid set for a board that may see a miswired connector or a stalled load. Package is SC-74A (SOT-753) with the supplier device package listed as SOT-23-5 — these are effectively the same footprint: 5-pin, 0.95 mm pitch, 2.9 x 1.6 mm body. The enable pin (Control Features) allows the LDO to be shut down externally, pulling the output to high-Z and dropping the supply current to near zero.","metaTitle":"Analog Devices MAX8867EUK25 LDO, 150mA, 2.5V Fixed, SOT-23-5","metaDescription":"MAX8867EUK25 from Analog Devices: 150mA LDO, fixed 2.5V output, 63dB PSRR at 10kHz, SOT-23-5.
