LT1763CS8-1.8#PBF

Analog Devices · Linear Voltage Regulators (LDO) · SO-8

LT1763CS8-1.8#PBF from Analog Devices, in a SO-8. 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 OUT power_out Regulated output that supplies the load and requires a minimum 3.3µF output capacitor to prevent oscillations.
2 SENSE input Output sense pin and input to the error amplifier on the fixed 1.8V LT1763-1.8, connected to OUT (or at the load for Kelvin sensing) for best regulation, with about 10µA bias current at nominal output voltage.
3 GND power_in Ground pin; the bottom of any output-setting divider should connect directly to the GND pins.
4 BYP passive Reference bypass pin clamped internally to ±0.6V; a capacitor of up to 0.01µF from OUT lowers noise to 20µVRMS, and the pin is left unconnected if unused.
5 SHDN input Shutdown input that turns the output off when pulled low, can be driven by 5V or open-collector logic with pull-up, must be tied to VIN if unused, and the device is in shutdown if it is left unconnected.
6 GND power_in Ground pin, one of the GND pins 3, 6 and 7.
7 GND power_in Ground pin, one of the GND pins 3, 6 and 7.
8 IN power_in Input supply pin that needs a 1µF to 10µF bypass capacitor if far from the main input filter capacitor and withstands reverse input voltage with no reverse current.
