MIC39500-2.5BU

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

The MIC39500-2.5BU is a fixed-output positive linear low-dropout regulator manufactured by Microchip Technology, providing a stable 2.5V output with a maximum current capacity of 5A. It utilizes Super Beta PNP technology to achieve an extremely low dropout voltage of typically 400mV at full load and features a guaranteed maximum dropout of 575mV across all operating conditions. The device supports input voltages up to 16V and includes comprehensive protection mechanisms such as overcurrent limiting, thermal shutdown, and reverse polarity protection. Designed for surface-mount installation in TO-263 packages, it operates reliably within a temperature range of -40°C to +125°C.

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

Verify the specific suffix 'BU' against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS3 standards and check moisture sensitivity level requirements during storage and handling. Confirm that the fixed 2.5V output aligns precisely with target circuit design parameters before procurement.

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

Select this component when a fixed 2.5V rail is required with high current capability up to 5A. Consider the TO-263 package for adequate thermal dissipation in space-constrained designs. Evaluate input voltage ranges to ensure sufficient headroom above the dropout threshold under worst-case load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

Part of the MIC39500/39501 family of 5A µCap Low-Voltage LDO regulators originally developed by Micrel and acquired by Microchip. These regulators are engineered for applications transitioning from traditional 2.5V or 3.3V supplies to newer, lower core voltage standards in computing and communication hardware.
