LMP7731MFX from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Amplifier output pin, rail-to-rail output stage capable of swinging within 50 mV of either supply rail under light load and sourcing/sinking up to tens of mA as specified in the Electrical Characteristics tables. |
| 2 | V- | power_in | Negative supply pin; with V+ it sets the supply voltage VS = V+ - V-, operating range 1.8V to 5.5V (absolute maximum 6.0V). |
| 3 | +IN | input | Non-inverting input pin; part of the rail-to-rail input stage with a common-mode voltage range of 0V to V+ and low input bias current of about ±1.5 nA. |
| 4 | -IN | input | Inverting input pin; part of the rail-to-rail input stage, protected by anti-parallel diodes to the other input limiting differential input voltage to about ±3 diode drops or ±20 mA. |
| 5 | V+ | power_in | Positive supply pin; operating supply voltage range 1.8V to 5.5V (absolute maximum 6.0V) referenced to V-. |
