LMV551M5 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 | IN+ | input | Non-inverting input of the amplifier; common-mode range extends from VSS-0.1V to VDD+0.1V (rail-to-rail input). |
| 2 | VSS | power_in | Negative supply or ground; for dual-supply operation (±1.05V to ±2.75V) bypass with a 0.1µF ceramic capacitor. |
| 3 | IN- | input | Inverting input of the amplifier; common-mode range extends from VSS-0.1V to VDD+0.1V (rail-to-rail input). |
| 4 | OUT | output | Rail-to-rail amplifier output; optimized for bandwidth, so use a series isolation resistor when driving capacitive loads. |
| 5 | VDD | power_in | Positive supply, 2.1V to 5.5V single supply (absolute maximum 7.5V between VDD and VSS), with a 0.1µF ceramic bypass capacitor placed close to the pin. |
