LT1763CS8-1.8#TRPBF

Analog Devices · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SO-8

LT1763CS8-1.8#TRPBF 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 Output supplies power to the load and requires a minimum output capacitor of 3.3µF to prevent oscillations.
2 SENSE input For the fixed-voltage LT1763-1.8, SENSE is the error amplifier input and should be connected to OUT for optimum regulation, with a bias current of 10µA at the nominal output voltage.
3 GND power_in Ground pin; connect the bottom of the output voltage setting divider directly to the GND pins for optimum load regulation.
4 BYP passive Bypass pin clamped internally to ±0.6V; a capacitor of up to 0.01µF from the output reduces output noise to a typical 20µVRMS over 10Hz to 100kHz, and the pin must be left unconnected if not used.
5 SHDN input Shutdown pin; the output is off when SHDN is pulled low, it can be driven by 5V logic or open-collector logic with a pull-up resistor, and it must be connected to VIN if unused.
6 GND power_in Ground pin, one of the GND pins (3, 6, 7) on the SO-8 package.
7 GND power_in Ground pin, one of the GND pins (3, 6, 7) on the SO-8 package.
8 IN power_in Input supply pin; a bypass capacitor of 1µF to 10µF is sufficient, and the IN pin voltage is rated ±20V absolute maximum.
