Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220
UA7908CKCS from Texas Instruments, in a TO-220. 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 | COMMON | power_in | Common terminal of the fixed -8 V negative regulator, used as the ground reference for input and output; the datasheet gives no separate voltage limit for this pin. |
| 2 | INPUT | power_in | Unregulated negative input supply; the µA7908C input voltage must be between -10.5 V and -25 V, and the absolute maximum input voltage is -35 V. |
| 3 | OUTPUT | power_out | Regulated -8 V output that delivers up to 1.5 A of output current, with internal short-circuit current limiting and thermal overload protection. |
