KIA Semicon Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
KIA78L05FG from KIA Semicon Tech, 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 | VOUT | power_out | Regulated +5V output. Typ 5.0V (min 4.75V, max 5.25V) over 7.0V<=VIN<=20V and 1mA<=IOUT<=40mA. Supports up to 100mA output current. A 0.1uF bypass capacitor to GND is recommended close to the pin for stability and transient response. |
| 2 | GND | power_in | Ground / common return for input and output. Quiescent current is typically 2.8mA flowing out of this pin. |
| 3 | VIN | power_in | Unregulated positive supply input. Absolute maximum 30V; must remain typically 1.7V above VOUT (dropout). A 0.33uF input bypass capacitor to GND is recommended close to the pin. |
