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. |
