ME7805A3G

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.
