LT1965EMS8E-2.5

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LT1965EMS8E-2.5#PBF is a fixed-output low dropout linear regulator manufactured by Analog Devices Inc., designed for applications requiring high performance and compact form factors. This component delivers a constant 2.5V output voltage with a maximum continuous load current of 1.1A. It operates from an input voltage range spanning 1.8V to 20V, ensuring stability across various supply conditions. The device features a typical power supply rejection ratio (PSRR) of 75dB at 120Hz, effectively filtering noise from the input source. With a maximum dropout voltage of 360mV at full load, it maintains regulation even when the input-to-output differential is minimal. The unit is housed in an 8-lead MSOP package with an exposed pad for enhanced thermal dissipation.
