XL317

XINLUDA · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOP-8

XL317 from XINLUDA, in a SOP-8. 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 VIN power_in Supply input pin; the input-to-output differential must stay within 2.5 V to 32 V under recommended conditions, and the absolute maximum input-output differential is 35 V.
2 VOUT power_out Voltage output pin, regulating over a 1.25 V to 32 V output range and supplying up to 100 mA.
3 VOUT power_out Voltage output pin, regulating over a 1.25 V to 32 V output range and supplying up to 100 mA.
4 ADJ input Output voltage adjustment pin, connected to a resistor divider to set VOUT; its current is typically 50 µA and at most 200 µA.
5 NC unconnected No connection.
6 VOUT power_out Voltage output pin, regulating over a 1.25 V to 32 V output range and supplying up to 100 mA.
7 VOUT power_out Voltage output pin, regulating over a 1.25 V to 32 V output range and supplying up to 100 mA.
8 NC unconnected No connection.
