LT6654AHS6-1.25#TRPBF

Analog Devices · Voltage References · TSOT-23-6

LT6654AHS6-1.25#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 Internal function pin that must be tied to ground near Pin 2.
2 GND power_in Primary device ground.
3 DNC unconnected Do not connect; keep leakage current from this pin to VIN or GND to a minimum.
4 VIN power_in Power supply input; bypass VIN with a 0.1µF capacitor to ground.
5 DNC unconnected Do not connect; keep leakage current from this pin to VIN or GND to a minimum.
6 VOUT power_out Output voltage; an output capacitor of 1µF minimum is required for stable operation.
