KIA78L05T

KIA Semicon Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

KIA78L05T 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. Nominal 5.0V (4.75V-5.25V over 7V<VIN<20V, 1mA<IOUT<40mA). Output current up to 100mA. Recommended output bypass capacitor 0.1uF placed close to the regulator for stability.
2 GND power_in Ground / common return for input and output. Quiescent current typ 2.8mA flows out this pin.
3 VIN power_in Unregulated positive input voltage. Absolute maximum 30V; must be at least ~1.7V above VOUT (dropout voltage typ 1.7V). Recommended input bypass capacitor 0.33uF placed close to the regulator.
