MP20046DN-F-LF-Z

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

The MP20046DN-F-LF-Z is a dual-channel, low-noise linear regulator manufactured by Monolithic Power Systems. It integrates two independent Low Dropout (LDO) regulators within a single compact package, designed for applications requiring high power supply rejection ratio (PSRR) and ultra-low output noise. The device supports an input voltage range of 1.8V to 5.5V and provides adjustable output voltages. Each channel delivers up to 300mA of load current with precise regulation. Key features include integrated enable pins for individual channel control, thermal shutdown protection, and current limit protection. The component operates reliably across a wide temperature range from -40°C to +125°C, making it suitable for demanding electronic environments.
