SL7533-8

Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

SL7533-8 from Slkor SLKORMICRO Elec, in a SOT-89-3. 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 for the regulator, as listed in the pin table for the series.
2 VIN power_in Input pin; the input voltage must not exceed the 36 V maximum rating (absolute limit -0.3 V to +36 V).
3 VOUT power_out Regulated 3.3 V output (3.234 V to 3.366 V at 10 mA) with at least 70 mA output current at VIN = VOUT + 2 V; the datasheet requires an output-to-ground capacitor greater than 2.2 µF.
