LT1964ES5-BYP#TRPBF

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

LT1964ES5-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 reference pin for the regulator; the datasheet gives no further limit for this pin.
2 IN power_in Supplies power to the device; 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, and the input supply is specified from -2.8V to -20V for the 200mA minimum-input condition, with the output maximum of -20V.
3 BYP passive Bypasses the internal reference to lower output voltage noise; a maximum of 0.01µF is recommended (typically 30µVRMS over 10Hz to 100kHz), and the pin must be left unconnected if not used.
4 ADJ input Input to the error amplifier with a 30nA bias current flowing out of the pin; ADJ is regulated to -1.22V referenced to ground, the output range is -1.22V to -20V, and the pin must not 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 Supplies power to the load and requires a minimum 1µF output capacitor (ESR of 3Ω or less recommended) to prevent oscillation; it must not be pulled more negative than IN in normal operation or more than 0.5V below IN during a fault.
