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

SL9193M18SE from Slkor SLKORMICRO Elec, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Power input voltage. Operating range 2V to 6.5V (absolute max -0.3 to 7V). Decouple with a 1µF ceramic capacitor to GND placed close to the pin.
2 GND power_in Device ground reference. Requires a wide, short copper trace back to the LDO from both input and output capacitor grounds to minimize parasitic inductance.
3 EN input Chip Enable, active high, CMOS logic input. VIH ≥ 1.2V enables the regulator; VIL ≤ 0.4V shuts it down (IQ ~0µA). High-impedance input (IEN ~1µA); must not be left floating - tie to VIN to keep the part always on.
4 NC unconnected No connect. Leave floating or tie to GND; not internally bonded.
5 VOUT power_out Regulated output voltage. For the -18 option this is 1.8V ±2%, up to 300mA (typical current limit 450mA, short-circuit current 50mA into 1Ω). Requires a 1µF X7R/X5R ceramic output capacitor to GND for stability.
