**HGSEMI** · Operational Amplifier · SOT-23-5

LMV721M5 from HGSEMI, 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 with rail-to-rail swing, able to deliver 70mA minimum output current at 25°C. |
| 2 | VSS | power_in | Negative supply (ground in single-supply operation); supply range VDD to VSS is 2.1V to 5.5V, absolute maximum 7.5V. |
| 3 | IN+ | input | Non-inverting input with rail-to-rail common-mode range from VSS-0.1V to VDD+0.1V. |
| 4 | IN- | input | Inverting input with rail-to-rail common-mode range from VSS-0.1V to VDD+0.1V. |
| 5 | VDD | power_in | Positive supply, 2.1V to 5.5V single supply, bypassed with a 0.1µF ceramic capacitor placed close to the pin. |
