LT1964IS5-5#TRMPBF 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; the SHDN pin threshold is referenced to this pin. |
| 2 | IN | power_in | Power input for the regulator; 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 maximum 0.01μF capacitor from OUT to this pin reduces output noise to a typical 30μVRMS over 10Hz to 100kHz, and the pin must be left unconnected if not used. |
| 4 | SHDN | input | Shutdown control referenced to GND; the output is off when the pin is within ±0.8V of GND and on when pulled beyond -1.9V or +1.6V, must be connected to IN if unused, and the device shuts down if left open. |
| 5 | OUT | power_out | Regulated output that supplies the load; a minimum 1μF output capacitor is required to prevent oscillations and the output must not be pulled more negative than IN during normal operation. |
