LTC6993IS6-1#TRPBF from Analog Devices, in a TSOT-23-6L. 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	TRIG	input	Trigger input; a rising edge (LTC6993-1/-2) or falling edge (LTC6993-3/-4) initiates the output pulse.
2	GND	power_in	Ground; tie to a low inductance ground plane for best performance.
3	SET	input	Pulse width setting input regulated to 1V above GND, with ISET range 1.25µA to 20µA programmed by a resistor to GND, and capacitance limited to less than 10pF.
4	DIV	input	Programmable divider and polarity input; VDIV is converted to a 4-bit DIVCODE whose MSB sets output polarity, with capacitance limited to less than 100pF.
5	V+	power_in	Supply voltage 2.25V to 5.5V, to be kept free of noise and ripple and bypassed to GND with a 0.1µF capacitor.
6	OUT	output	Output swinging from GND to V+ with approximately 30Ω output resistance, using a series resistor to limit current to 20mA when driving low impedance loads.
