LM317L

HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92-3

LM317L from HTC Korea TAEJIN Tech, in a TO-92-3. 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 ADJ passive Adjustment terminal that sets the output voltage; the datasheet gives an adjustable pin current of 46 µA typical and 100 µA maximum.
2 VOUT power_out Regulated output, adjustable from 1.2 V to 37 V, supplying more than 100 mA of load current.
3 VIN power_in Unregulated input; the datasheet specifies regulation with an input-output differential of 3 V to 40 V.
