MIC5233-3.3YM5-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 with an operating input voltage range of +2.3V to +36V. |
| 2 | GND | power_in | Ground pin for the regulator. |
| 3 | EN | input | Enable input: logic LOW (VEN max 0.6V) shuts the regulator down and logic HIGH (VEN min 2.0V) enables it, with VEN rated 0V to +36V. |
| 4 | NC | unconnected | No Connect on the fixed-output versions such as MIC5233-3.3YM5; on the adjustable version this pin is the ADJ feedback input connected to the resistive voltage divider. |
| 5 | OUT | power_out | Regulator output that requires a capacitor of 2.2µF or greater for stability, with a maximum recommended ESR of 3Ω. |
