LM317EMPRG

HANSCHIP semiconductor · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

LM317EMPRG from HANSCHIP semiconductor, in a SOT-223. 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 passive Adjust terminal sets the output voltage with the two external resistors; the adjust current Iadj is designed to stay below 100 µA and held constant, and all quiescent current is returned to the output.
2 VOUT power_out Regulated output terminal, rated for up to 1.5 A and adjustable from 1.2 V to 37 V, with a maximum input-output differential of 40 V.
3 Vin power_in Unregulated input supply terminal; the input-to-output voltage difference must stay within 40 V (VI-VO maximum 40 V), and an input bypass capacitor of 0.1 µF or 1.0 µF is recommended.
