LM317HVT

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

LM317HVT from Texas Instruments, in a TO-220. 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 ADJ input Adjust pin; the regulator maintains a constant 1.25V reference voltage between VOUT and ADJ to set the output voltage through external resistor network.
2 VOUT power_out Output voltage pin; supplies regulated output voltage from 1.25V to 57V with maximum 1.5A output current capability.
3 VIN power_in Input supply voltage pin; accepts input voltage with maximum input-to-output differential of 60V.
