78N06G-AB3-R

UTC Unisonic Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

78N06G-AB3-R from UTC Unisonic Tech, in a SOT-89. 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 +6.0V output (typ), tolerance ±4% at TJ=25°C. Delivers up to 300mA. A 0.1uF ceramic bypass capacitor to GND is recommended close to the pin for stability and transient response.
2 GND power_in Common ground reference for the regulator. On SOT-89 this pin is also the large center tab used for heat sinking to the PCB copper.
3 VIN power_in Unregulated positive input supply, absolute max 30V. For 78N06, must be ≥8.5V (with ≥1.7V dropout headroom above VOUT). A 0.33uF input bypass capacitor to GND close to the pin is recommended.
