SK6513T3A-33

Suntek · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L

SK6513T3A-33 from Suntek, in a SOT-89-3L. 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 VOUT power_out Regulated output of the SK6513T3A; output accuracy is <±2% and output current is 150mA typical, up to 300mA at VIN=7V and VOUT=5V.
2 GND power_in Ground reference pin for the regulator.
3 VIN power_in Power input; the input voltage range is 4.75V to 40V (absolute maximum -0.3V to 45V).
