LT1964ES5-SD#TRPBF 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 for the regulator; the SHDN pin thresholds are referenced to this pin. |
| 2 | IN | power_in | Supply input; a 1µF to 10µF bypass capacitor is sufficient and is required if the device is more than six inches from the main input filter capacitor, and the input must stay more positive than OUT, ADJ and SHDN during normal operation. |
| 3 | SHDN | input | Shutdown control referenced to GND: the output is off when pulled within ±0.8V of GND and on when pulled beyond -1.9V or +1.6V, must not be pulled more than 0.5V below IN during a fault, and must be connected to IN if unused. |
| 4 | ADJ | input | Input to the error amplifier, regulated to -1.22V referenced to ground, with a 30nA bias current flowing out of the pin, and it cannot be pulled more negative than IN in normal operation or more than 0.5V more negative than IN during a fault. |
| 5 | OUT | power_out | Regulated output that requires a minimum 1µF output capacitor with ESR of 3Ω or less to prevent oscillation, and it cannot be pulled more negative than IN in normal operation or more than 0.5V below IN during a fault. |
