MIC29151S-5.0

HGSEMI · Linear Voltage Regulators (LDO) · TO-263-5

MIC29151S-5.0 from HGSEMI, in a TO-263-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Logic-level ON/OFF enable input with TTL/CMOS compatible thresholds (low/OFF 0.8 V max, high/ON 2.4 V min), which may be tied directly to VIN if not needed for control.
2 IN power_in Input supply pin; the operating input voltage range is 2.3 V to 26 V, with transient spikes between -20 V and +30 V survived.
3 GND power_in Ground pin, with the Tab also grounded; GND pin current is the regulator quiescent current.
4 OUT power_out Regulated output pin, which requires a 10 µF minimum output capacitor for stability at full load.
5 FLAG output Open-collector error flag that pulls low when the output falls 5% below its expected value, and may sink 10 mA.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
