LM317LZ-AP

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92

LM317LZ-AP from STMicroelectronics, in a TO-92. 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 ADJUST input Adjustment terminal for setting output voltage via external resistor divider; adjustment pin current 50 to 100 µA.
2 IN power_in Unregulated input supply voltage; maximum input-to-output differential voltage 40 V.
3 OUT output Regulated output voltage adjustable from 1.2 to 37 V, capable of supplying up to 100 mA of load current.
