LT1761ES5-BYP#TRPBF

Analog Devices · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSOT-23-5

LT1761ES5-BYP#TRPBF from Analog Devices, in a TSOT-23-5. 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 IN power_in Input supply pin, accepting 1.8V to 20V and withstanding reverse voltage; a 1μF to 10μF bypass capacitor is needed if the device is more than six inches from the main input filter capacitor.
2 GND power_in Ground.
3 BYP passive Bypass pin, clamped internally to ±0.6V from ground; a capacitor of up to 0.01μF from OUT to this pin lowers output noise to a typical 20μVRMS, and the pin is left unconnected if unused.
4 ADJ input Adjust pin for the adjustable LT1761 and the error amplifier input, internally clamped to ±7V with 30nA bias current, and regulated to 1.22V above ground.
5 OUT power_out Regulated output supplying power to the load, requiring a minimum output capacitor of 1μF to prevent oscillations.
