LT1763CS8#PBF

Analog Devices · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8-150mil

LT1763CS8#PBF from Analog Devices, in a SOIC-8-150mil. 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 Output supplies power to the load and requires a minimum output capacitor of 3.3µF to prevent oscillations.
2 SENSE/ADJ input For the adjustable LT1763 this is the ADJ error-amplifier input, clamped to ±7V with a 30nA bias current, and it regulates the ADJ pin to 1.22V referenced to ground for an output range of 1.22V to 20V.
3 GND power_in Ground; connect the bottom of the output voltage setting resistor divider directly to the GND pins for optimum load regulation.
4 BYP passive Bypass pin clamped internally to ±0.6V that takes a maximum 0.01µF capacitor from output to reduce output noise to a typical 20µVRMS, and must be left unconnected if not used.
5 SHDN input Shutdown input that turns the output off when pulled low, can be driven by 5V logic or open-collector logic with a pull-up, and must be connected to VIN if unused.
6 GND power_in Ground; connect the bottom of the output voltage setting resistor divider directly to the GND pins for optimum load regulation.
7 GND power_in Ground; connect the bottom of the output voltage setting resistor divider directly to the GND pins for optimum load regulation.
8 IN power_in Input supply pin, rated ±20V absolute maximum, that should have a 1µF to 10µF bypass capacitor when the device is more than six inches from the main input filter capacitor.
