MIC37152BR

Product Overview

The MIC37152BR from Microchip Technology is a positive adjustable linear voltage regulator intended for single-output regulation in surface-mount power stages. It is specified for a maximum input voltage of 6V and an adjustable output range from 1.24V to 5.5V, with a rated output current of 1.5A. The device uses an S-PAK-5 package, also identified as SPAK-5 with five leads plus a tab, and includes an enable control feature. Its lifecycle status is listed as Obsolete, which should be considered for new designs and long-term availability planning.

Key Features

• Single positive adjustable regulator output with a 1.24V minimum output and a 5.5V maximum output.
• Rated for 1.5A output current and a maximum dropout voltage of 0.5V at 1.5A.
• Supports a maximum input voltage of 6V and includes an enable control feature.
• Provides over current, over temperature, and reverse polarity protection.
• Surface-mount SPAK-5 / S-PAK-5 package with five leads plus tab.
• Operating temperature range specified as -40°C to 125°C.
• Lifecycle status is Obsolete as supplied.

Applications

• Regulating a local positive supply for logic and sensor circuitry.
• Providing an adjustable output voltage from an input up to 6V in board-level power distribution.
• Using the enable control feature for output control during system power management.
• Applying linear regulation where the load remains within the 1.5A output current and 0.5V dropout at 1.5A limits.

Design & Procurement Notes

For new designs, the Obsolete status should prompt review of long-term support and procurement risk. The 1.24V to 5.5V adjustable output, 6V maximum input, and 0.5V dropout at 1.5A define the operating limits; designers should verify that the selected output voltage, input voltage, and load current remain within these values. The enable control feature should be reviewed if output control is required, and the over current, over temperature, and reverse polarity protection features should still be validated in the final circuit. The surface-mount S-PAK-5 package with five leads plus tab should be reviewed for board layout.
