Fixed 5V LDO in SOT-23-5 — 150 mA with 0.5 V dropout
The MIC5235-5.0YM5-TR from Microchip Technology is a positive fixed-output LDO regulator delivering 5 V at up to 150 mA. It comes in the SOT-23-5 (SC-74A) package, a standard footprint for low-power linear regulation on space-constrained boards. With a 24 V maximum input, it handles unregulated supplies like 9 V or 12 V rails with plenty of headroom.
35 µA quiescent current — enable pin for power gating
Quiescent current is 35 µA typical, which keeps the regulator's own draw low in always-on or battery-backed applications. The Enable pin (active-high logic input) lets the system shut down the LDO entirely — pulling EN low drops the supply current to near zero, useful for sequencing or sleep-mode power gating. The 150 mA output is suited for powering sensor front-ends, MCU analog rails, or CAN transceivers that need a clean 5 V supply away from the main switching regulator noise.
Protection set — over-current, over-temperature, reverse polarity
Built-in protection includes over-current limiting, thermal shutdown, and reverse polarity protection. The thermal shutdown prevents die damage if the load exceeds the package's dissipation capability; the reverse polarity block protects the regulator if the input is accidentally reversed during bench testing or field wiring. Lifecycle status is Active per Microchip Technology. The part is ROHS3 compliant.
