MIC5225-3.3YM5-TR
Microchip Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
MIC5225-3.3YM5-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; the datasheet gives an operating supply voltage range of 2.3V to 16V (absolute maximum −20V to 18V). |
| 2 | GND | power_in | Ground connection for the regulator. |
| 3 | EN | input | Enable input: logic low or open shuts the regulator down, logic high enables it; VIL maximum is 0.6V, VIH minimum is 2.0V, and the enable voltage operating range is 0V to 16V. |
| 4 | NC | unconnected | No connect on the fixed-voltage versions such as the -3.3 part; this pin is not used. On the adjustable version this pin is ADJ, the feedback input. |
| 5 | OUT | power_out | Regulator output; the output needs a capacitor of 1.0µF or greater for stability, with a maximum recommended ESR of 300mΩ. |
