SL9400L33SE

Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

SL9400L33SE from Slkor SLKORMICRO Elec, in a SOT-23-5. 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 VIN power_in Power input voltage; the input range is 1.5V to 8V per the electrical characteristics, and the absolute maximum rating is -0.3V to +9V.
2 GND power_in Ground reference pin for the regulator.
3 EN input Chip enable, active high: logic low is 0.4V max and logic high is 1.2V min to VIN, with input current up to 1µA; the pin is high impedance.
4 NC unconnected No connection.
5 VOUT power_out Regulated output voltage; the output current limit is 400mA typical and the maximum load current rating is 450mA.
