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. |
