OPA313IDBVR 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	Op-amp output. Rail-to-rail output stage; short-circuit current typically ±15 mA at Vs=5.5V. Output swing to within ~5 mV of the rails with RL=100 kΩ.
2	V-	power_in	Negative supply / ground rail. For single-supply operation tie to GND; for split supply connect to negative rail. Supply range 1.8V to 5.5V total (V+ minus V-).
3	+IN	input	Non-inverting input. Rail-to-rail common-mode range from (V-)-0.2V to (V+)+0.2V. Input bias current typically ±0.2 pA (CMOS input), differential input capacitance 1 pF.
4	-IN	input	Inverting input. Rail-to-rail common-mode range from (V-)-0.2V to (V+)+0.2V. Input clamped to supply rails by internal diodes; limit signal swing beyond rails to ≤10 mA input current.
5	V+	power_in	Positive supply rail. Operating range +1.8V to +5.5V (referenced to V-). Quiescent current typically 50 µA/channel. Bypass with 0.1 µF ceramic close to the pin.
