MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
MIC5219-2.8YM5-MS 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; the datasheet gives a recommended input range of 2.0V to 24V and an absolute maximum VIN to GND of 0.3V to 24V. |
| 2 | GND | power_in | Ground pin; the input and output capacitor ground connections must return to this pin using as wide and as short a copper trace as is practical. |
| 3 | EN | input | Enable control input for the regulator; the datasheet does not state enable threshold voltages. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator; use an output capacitor meeting the minimum 1mΩ ESR and effective capacitance of 1µF to 22µF, placed close to the VOUT and GND pins. |
