MIC5528-3.3YMT-TR from Microchip Tech, in a TDFN-6-EP(1.2x1.2). 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 | VOUT | power_out | Regulated output voltage; when the regulator is disabled, an internal 25 Ω load is switched in to discharge the external capacitors. |
| 2 | VOUT | power_out | Regulated output voltage (second output pin, internally tied to pin 1); when the regulator is disabled, an internal 25 Ω load is switched in to discharge the external capacitors. |
| 3 | GND | power_in | Ground reference for the regulator. |
| 4 | EN | input | Active-high enable: high turns the output on and low turns it off; the internal pull-down means the pin can be left floating, and the enable voltage operating range is 0 V to VIN. |
| 5 | NC | unconnected | No connection. |
| 6 | VIN | power_in | Supply input; operating range is +2.5 V to +5.5 V, with an absolute maximum of -0.3 V to +6 V. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
