LT1761ES5-5#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 pin that supplies power to the device; a bypass capacitor of 1µF to 10µF is sufficient, and it is required if the device is more than six inches from the main input filter capacitor. |
| 2 | GND | power_in | Ground pin. |
| 3 | SHDN | input | Shutdown pin for fixed -SD style devices: 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 if unused it must be connected to VIN because the device will not function if SHDN is left unconnected. |
| 4 | BYP | passive | Bypass pin clamped internally to ±0.6V (one VBE) from ground; a capacitor from OUT to this pin of at most 0.01µF lowers output noise, and the pin must be left unconnected if not used. |
| 5 | OUT | power_out | Output pin that supplies the load; a minimum output capacitor of 1µF is required to prevent oscillations, with larger values needed for large transient loads. |
