LT1964ES5-BYP#PBF from Analog Devices, in a SOT-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 | GND | power_in | Ground reference pin for the regulator. |
| 2 | IN | power_in | Input power pin; a bypass capacitor of 1μF to 10μF is sufficient and is required if the device is more than six inches from the main input filter capacitor. |
| 3 | BYP | passive | Reference bypass pin; a capacitor of up to 0.01μF from OUT lowers output noise to a typical 30μVRMS over 10Hz to 100kHz, and the pin must be left unconnected if not used. |
| 4 | ADJ | input | Error amplifier input that servos to -1.22V referenced to ground, with a bias current of 30nA flowing out of the pin, and it cannot be pulled more than 0.5V more negative than IN during a fault condition. |
| 5 | OUT | power_out | Output pin that supplies the load, requiring a minimum 1μF output capacitor to prevent oscillations, and it cannot be pulled more negative than IN during normal operation. |
