MIC37252BU

Product Overview

The MIC37252BU from Microchip Technology is a surface-mount positive adjustable-output linear voltage regulator for single-output regulation. It supports a maximum input voltage of 6 V and an adjustable output from 1.24 V to 5.5 V at up to 2.5 A. The device specifies a maximum dropout voltage of 1 V at 2.5 A and includes an enable control feature. Protection functions cover over-current, over-temperature, and reverse-polarity conditions. The part uses a TO-263-5 surface-mount package with D2PAK 5-lead plus tab construction, and it is rated for an operating temperature range of -40°C to 125°C.

Key Features

• Positive adjustable output with a specified range from 1.24 V to 5.5 V.
• Single regulator channel delivering up to 2.5 A output current.
• Maximum input voltage of 6 V and maximum dropout voltage of 1 V at 2.5 A.
• Enable control feature for output activation or deactivation.
• Protection features include over-current, over-temperature, and reverse-polarity protection.
• Surface-mount TO-263-5 package with D2PAK 5-lead plus tab construction.
• Specified operating temperature range of -40°C to 125°C.

Applications

• Adjustable positive rail for embedded control boards requiring output voltages from 1.24 V to 5.5 V.
• Single-output regulation for regulated positive supply paths up to 2.5 A.
• Enable-controlled output management in surface-mount power assemblies.
• Protected input supply paths using over-current, over-temperature, and reverse-polarity protection.

Design & Procurement Notes

Designers should select the output voltage and input headroom so that the available input voltage remains above the chosen output plus the specified dropout at the actual load current, while staying within the 6 V maximum input limit. The enable control can be used to manage output state in system power sequencing, and the protection features should be considered as part of fault-handling strategy. The TO-263-5 surface-mount package with tab construction requires attention to board footprint and pad layout. The -40°C to 125°C operating range should be matched to the intended ambient conditions.
