MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220
ME7805A3G from MICRONE, in a TO-220. 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 | Input | power_in | Unregulated input supply, with a maximum input voltage (VIN) of 35 V; the input must stay typically 2.0 V above the output, and a 0.33 µF (or larger) low-ESR bypass capacitor should be mounted as close as possible across the input and GND terminals. |
| 2 | GND | power_in | Common ground shared by input and output that must be kept low-impedance, since the regulator has no external sense lead, so ground loops and lead resistance drops should be minimized. |
| 3 | Output | power_out | Regulated 5 V output (5 V ±5% over the temperature range) that can deliver up to 1.2 A of output current, with an optional output capacitor Co that improves transient response but is not required for stability. |
