LM317AEMPRG

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

LM317AEMPRG 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 The adjust pin is the reference divider node; the datasheet states the adjust current is controlled below 100 µA (typical 50 µA, change 0.2 to 5 µA over line and load) and is held constant, so it is connected to ground through R2 to set the output voltage.
2 VOUT power_out The regulated output; the datasheet rates the maximum output current at 1.5 A, with minimum load current of 3.5 to 10 mA needed to maintain regulation.
3 Vin power_in The unregulated input supply; the input-to-output differential must stay within 3 V to 40 V (absolute maximum 40 V).
