LT1964IS5-BYP#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; the ADJ pin voltage is referenced to ground at -1.22V. |
| 2 | IN | power_in | Power input to the device (±20V absolute maximum); a 1µF to 10µF bypass capacitor is sufficient and is required if more than six inches from the main input filter capacitor, and the SHDN function is internally connected to this pin on the LT1964-BYP. |
| 3 | BYP | passive | Reference bypass pin; a capacitor of up to 0.01µF from OUT to this pin reduces output noise to a typical 30µVRMS (10Hz to 100kHz), and it must be left unconnected if not used. |
| 4 | ADJ | input | Error amplifier input of the adjustable regulator, servoed to -1.22V with 30nA bias current flowing out of the pin, setting an output range of -1.22V to -20V, and it cannot be pulled more than 0.5V more negative than IN. |
| 5 | OUT | power_out | Regulator output supplying up to 200mA; requires a minimum 1µF output capacitor to prevent oscillations and cannot be pulled more than 0.5V more negative than IN during a fault. |
