# TL317CLP

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92

TL317CLP from Texas Instruments, in a TO-92. 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 | INPUT | power_in | Input supply voltage; the input-to-output differential must stay between 2.5 V minimum and 35 V maximum (VI - VO). |
| 2 | OUTPUT | power_out | Regulated output voltage; the output delivers up to 100 mA and the output terminals are internally connected to each other. |
| 3 | ADJUSTMENT | passive | Supply reference voltage pin; with an external resistor divider the output is set from 1.25 V to 32 V. |

## CAD (KiCad official)

- Symbol: `TL317CLP`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92 (KiCad packages3D, STEP)
- 3D model files: `tl317clp-etched.step` / `tl317clp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tl317clp.step` / `tl317clp.glb` are the bare package body.
