MP20041DGT-PP-LF-Z

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

The MP20041DGT-PP-LF-Z is a dual-channel low-dropout linear regulator manufactured by Monolithic Power Systems. It operates within an input voltage range of 2.5V to 6.0V and provides adjustable output voltages from 1.2V to 3.6V with 1% accuracy in 100mV steps. Each channel delivers up to 300mA of load current. The device features ultra-low noise output of 11μVRMS without requiring bypass capacitors and offers high power supply rejection ratio (PSRR) of 72dB at 10kHz. Quiescent current is 114µA when both channels are active, dropping to near zero when disabled. It includes overcurrent protection and thermal shutdown.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the complete part number including suffixes such as -LF-P or -LF-Z against official MPS documentation to ensure correct packaging and lead-free status. Confirm that the specific variant matches your required enclosure type and reel specifications. Cross-reference ordering information directly with manufacturer sources to avoid discrepancies in component revisions or environmental compliance certifications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when designing circuits requiring dual isolated low-noise rails from a single input source. Ensure the input voltage remains within the specified 2.5V to 6.0V window to maintain proper regulation. Consider the 300mA per channel limit when sizing thermal solutions. Verify that the application does not exceed the maximum junction temperature limits under full load conditions.
