LT1964ES5-BYP#PBF

Analog Devices · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

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.
