Overview

Description

The LT3042EDD#PBF is a low-dropout (LDO) linear voltage regulator designed by Analog Devices. It is part of the LT3042 series, known for its high-performance characteristics. This device provides a low noise, high precision output, making it suitable for applications that require a clean and stable voltage supply, such as RF systems, precision instrumentation, and high-speed data converters.
Key features of the LT3042 include an ultra-low noise floor of 0.8µVRMS over a 10Hz to 100kHz bandwidth and an exceptionally high power supply rejection ratio (PSRR) of up to 79dB at 1MHz. These features help minimize the impact of input voltage variations on the output, ensuring a stable and precise output voltage.
The device operates over a wide input voltage range of 1.8V to 20V, with an output current capability of up to 200mA. The regulator also offers a programmable current limit, along with thermal protection to prevent overheating.
Packaged in a thermally enhanced 10-lead 3mm × 3mm DFN, the LT3042EDD#PBF is suitable for compact designs requiring efficient heat dissipation. It is RoHS compliant and ideal for applications where space and performance are critical.
