TSV631ILT from UMW, 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	IN+	input	Non-inverting analog input of the op-amp. Rail-to-rail input; common-mode range extends from (VCC-)-0.1 V to (VCC+)+0.1 V. Absolute-max input voltage: (VCC-)-0.2 V to (VCC+)+0.2 V.
2	VCC-	power_in	Negative supply rail (ground for single-supply operation). Total supply voltage (VCC+ - VCC-) rated 1.5 V to 5.5 V; absolute-max 6 V.
3	IN-	input	Inverting analog input of the op-amp. Rail-to-rail input; typical input bias current 1 pA. Combined with IN+ tolerates a differential voltage up to ±VCC.
4	OUT	output	Rail-to-rail amplifier output. Delivers up to ~63 mA at VCC=5 V (Isink/Isource typ 69/74 mA); VOH/VOL swing within a few mV of the supply rails into a 10 kΩ load.
5	VCC+	power_in	Positive supply rail. Operating range 1.5 V to 5.5 V (absolute-max 6 V). Supply current 60 µA typ at 5 V; drops to ~5 nA in shutdown when SHDN pin is asserted (not brought out on this 5-pin package).
