3V fixed LDO — what the ratings mean for the rail
The MAX8867EUK30+T is a 3V fixed-output positive LDO from Analog Devices, rated for 150 mA continuous output. Its 63 dB PSRR at 10 kHz holds ripple rejection into the switching-regulator noise band. The part includes over-current, over-temperature, reverse polarity, and short-circuit protection, so it handles field faults without latching or burning. Enable pin lets you sequence the rail or shut down for sleep — quiescent current is 180 µA active, 100 µA max supply draw. Operating temperature covers -40°C to 85°C, which fits industrial control, outdoor telecom, and automotive cabin environments.
Package and footprint
Housed in a SOT-23-5 (SOT-753) surface-mount package. The SOT-23-5 footprint is common across many LDOs and single-gate logic, so board layout is straightforward. Tape & Reel or Cut Tape options for the procurement side.
Lifecycle and sourcing
Listed as Active with ROHS3 compliance. No end-of-life notice issued.
