Description
The LT1965EDD#PBF is a low-dropout (LDO) linear voltage regulator designed to provide a stable output voltage with low noise and low dropout voltage, making it suitable for power-sensitive applications. It is produced by Analog Devices, Inc. and formerly by Linear Technology. This device can supply up to 1.1A of output current with a typical dropout voltage of 300mV. One of its notable features is its low noise performance, with only 40µV RMS over a 10Hz to 100kHz bandwidth, making it ideal for powering noise-sensitive circuitry.
The LT1965 operates with an input voltage range from 1.8V to 20V, offering flexibility in different applications. The output voltage can be set using an external resistor divider, allowing for a wide range of potential output settings. The device includes several protection features such as thermal overload protection, reverse-battery protection, and reverse-current protection. It is housed in a thermally enhanced 8-lead plastic DFN package (EDD suffix) for efficient heat dissipation. The "#PBF" suffix indicates a lead-free, RoHS-compliant package.
