MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
SPX3819M5-L-2-8 from MSKSEMI, 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 | Input of supply voltage, with an operating range of 2V to 24V; place a 1µF or larger input capacitor close to the VIN and GND pins. |
| 2 | GND | power_in | Ground reference pin; input and output capacitor ground connections must return to this pin using as wide and as short a copper trace as is practical. |
| 3 | CE | input | Enable control input for the regulator; the datasheet does not state the active level in the pin table. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, stable with a ceramic or tantalum output capacitor between 1µF and 22µF placed close to the VOUT and GND pins. |
