LR7150-T

LR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

LR7150-T from LR, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VSS power_in Ground / negative supply return. Common reference for VIN and VOUT.
2 VOUT power_out Regulated 5.0 V output (±2% for LR7150, ±3% for LR7150A). Delivers up to 50 mA; requires a 10 μF ceramic output capacitor (COUT) to GND for stability.
3 VIN power_in Unregulated input supply. Operating range up to 24 V (32 V absolute max); for 5.0 V output, use VIN ≥ 6.0 V (recommended VIN = 7.0 V for full-spec operation). Requires a 10 μF ceramic input capacitor (CIN) to GND.
