SK7533-1

Shikues · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

SK7533-1 from Shikues, in a SOT-89. 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 GND power_in Ground pin, the common reference for the regulator; the datasheet's absolute maximum ratings are a supply voltage of -0.3V to 33V and an operating temperature of -40°C to 85°C.
2 VIN power_in Input pin, rated up to 24V in the electrical characteristics (absolute maximum supply voltage -0.3V to 33V).
3 VOUT power_out Regulated output pin giving 3.3V nominal (3.201V to 3.399V, ±3%) for SK7533-1 with up to 100mA output current.
