PB137ACV

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

PB137ACV from STMicroelectronics, in a TO-220. 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 VIN power_in Unregulated DC input voltage, absolute maximum 40 V; electrical characteristics are specified at VI = 18 V with line regulation tested for VI = 16 to 28.7 V.
2 GND power_in Ground reference pin for the regulator, with quiescent current typically 4 mA and 8 mA maximum at TJ = 25 °C.
3 VOUT power_out Regulated 13.7 V output (±1 % in AC selection at 25 °C) delivering over 1.5 A with internal current limiting, and reverse leakage current of max 10 µA when VI is floating.
