MIC29501-5.0WU

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

The MIC29501-5.0WU is a fixed-output low-dropout linear regulator manufactured by Microchip Technology, delivering a stable 5 V output with a maximum current capacity of 5 A. It operates within an input voltage range of 2.3 V to 26 V and features a typical dropout voltage of 370 mV at full load, with a maximum specification of 600 mV. The device incorporates five pins for enhanced control, including an enable pin and an error flag output. It maintains line regulation of 0.06% and load regulation of 0.2%. The component is designed for robust performance across an extended operating temperature range from -40°C to +125°C.

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

Verify the specific suffix 'WU' corresponds to the TO-263-5 surface-mount package configuration when sourcing. Confirm that the ordering part number includes the correct tube packaging designation if reel quantities are not required. Ensure compatibility with RoHS standards for environmental compliance in final assembly processes.

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

Select this component when a fixed 5 V output is required with high current capability up to 5 A. The TO-263-5 package offers a balance between thermal dissipation and surface-mount convenience. Consider the integrated enable and flag features if system monitoring and external control logic are necessary for the application design.
