LT1761IS5-SD#TRMPBF 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; a 1μF to 10μF bypass capacitor is needed if the device is more than six inches from the main input filter capacitor, and the pin withstands reverse voltage (absolute maximum ±20V). |
| 2 | GND | power_in | Ground. |
| 3 | 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 resistor, must be tied to VIN if unused and must not be left unconnected. |
| 4 | ADJ | input | Adjust pin and error amplifier input, referenced to 1.22V, internally clamped to ±7V with 30nA bias current, setting an output range of 1.22V to 20V through an external resistor divider. |
| 5 | OUT | power_out | Regulated output supplying the load, requiring a minimum output capacitor of 1μF to prevent oscillations. |
