Présentation

Description

The LT3042EDD#PBF is a high-performance, low-dropout (LDO) linear regulator from Analog Devices, designed for applications requiring ultra-low noise and high accuracy. It features a wide input voltage range, typically from 2.0V to 20V, and can supply up to 200mA of output current. The LT3042 is specifically engineered to provide an extremely low noise output, with a typical noise floor of 0.8µVRMS (10Hz to 100kHz), making it suitable for sensitive analog circuits like RF and precision instrumentation.
Key features include a high power supply rejection ratio (PSRR), programmable current limit, and the ability to parallel multiple LT3042s for higher current applications. Its adjustable output voltage can be set via external resistors. Additionally, the device offers thermal protection and a precision enable pin for better control and sequencing in power management designs.
The LT3042EDD#PBF package is a 10-lead DFN, ensuring compact size and efficient thermal management, which is ideal for space-constrained applications.
