DS4303R+T&R

Maxim Integrated · Voltage References · SOT-23-5

DS4303R+T&R from Maxim Integrated, 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 ADJ input Adjust control input; pulling ADJ low and holding it for at least tADJ (100 ns) starts the VOUT self-adjust procedure, and it should not be toggled again until the procedure is complete.
2 GND power_in Ground reference for all voltages, with the substrate connected to ground.
3 VIN power_in Sample voltage input that sets the target VOUT; it must be stable before and throughout the adjustment and stays within 0.3 V to VCC - 0.3 V.
4 VOUT output Voltage output that sources or sinks up to ±1 mA, with continuous short-circuit protection to GND.
5 VCC power_in Power-supply input, specified for 2.4 V to 3.6 V single-supply operation.
