# 79L05

**Shikues** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

79L05 from Shikues, in a SOT-89-3. 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 | GND | power_in | Ground / common reference for both input and output. For a negative regulator this is the return terminal shared between VIN and VOUT. |
| 2 | VIN | power_in | Unregulated negative input voltage. Absolute maximum -35V for 79L05-79L15 variants (-40V for 79L18-79L24). Recommended input bypass capacitor Ci = 0.33 µF to ground. |
| 3 | VOUT | power_out | Regulated negative output, nominally -5V (typ), tolerance -4.8V to -5.2V at TJ=25°C. Maximum output current 0.15A. Recommended output capacitor Co = 0.1 µF to ground. |

## CAD (KiCad official)

- Symbol: `79L05`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89-3 (KiCad packages3D, STEP)
- 3D model files: `79l05-etched.step` / `79l05-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `79l05.step` / `79l05.glb` are the bare package body.
