LT1790BIS6-1.25#TRPBF

Analog Devices · Voltage References · TSOT-23-6

LT1790BIS6-1.25#TRPBF from Analog Devices, in a TSOT-23-6. 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 GND power_in Ground reference pin; connect the 1µF output capacitor return to this pin per the typical application.
2 GND power_in Ground reference pin; connect the 1µF output capacitor return to this pin per the typical application.
3 DNC unconnected Do not connect; leave this pin floating.
4 VIN power_in Supply input; the datasheet specifies 2.6V ≤ VIN ≤ 18V with 20V absolute maximum input voltage.
5 DNC unconnected Do not connect; leave this pin floating.
6 VOUT power_out Reference voltage output; the device can both source and sink current.
