MS8051 from Hangzhou Ruimeng 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 | OUT | output | Amplifier output, rail-to-rail, with output current of 130 mA typical (84 mA minimum). |
| 2 | -VS | power_in | Negative supply (ground in single-supply use); the supply voltage VS is 2.5V to 5.5V and the absolute maximum between supplies is 7.5V. |
| 3 | +IN | input | Non-inverting input with an input common-mode range of -0.2V to +3.8V at VS=5V. |
| 4 | -IN | input | Inverting input of the voltage-feedback amplifier. |
| 5 | +VS | power_in | Positive supply, 2.5V to 5.5V operating, bypassed with a 0.1uF ceramic capacitor placed close to the pin. |
