Microchip Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
MIC5205-3.8YM5-TR from Microchip Tech, 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 | IN | power_in | Supply input; the datasheet's operating range is +2.5V to +16V. |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | CMOS-compatible enable/shutdown input: logic-high (above 2V) enables the regulator, while logic-low (0.4V or below) or open shuts it down. |
| 4 | BYP | passive | Reference bypass: a external 470 pF capacitor to GND reduces output noise, and the pin may be left open. |
| 5 | OUT | output | Regulated output; an output capacitor of at least 2.2 µF is recommended when a 470 pF CBYP is used (1.0 µF minimum without CBYP). |
