# SL54M30SE

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

SL54M30SE 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 pin; the datasheet gives an input range of 3V to 45V (absolute maximum -0.3V to +55V) and recommends a 1uF ceramic capacitor to GND placed close to the pin. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Chip enable, active high (logic high min 1V, logic low max 0.4V, absolute maximum -0.3V to +55V); it is neither pulled up nor pulled down internally, so it must not float and should be tied to VIN when unused. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output voltage pin (3.0V for the SL54M30SE); the datasheet gives an absolute maximum of -0.3V to +6V, a 350mA typical maximum output current and a recommended minimum 1uF ceramic output capacitor. |
