MIC49200WR

Product Overview

The MIC49200WR from Microchip Technology is a positive adjustable linear voltage regulator for single-output low-dropout regulation. It provides up to 2A output current from an input voltage up to 6.5V and supports an adjustable output range from 0.9V to 5V. The device includes an enable control and protection against over-current and over-temperature conditions. Its operating temperature range is -40°C to 125°C, and it uses a surface-mount S-PAK-5 package with five leads plus a tab.

Key Features

• Positive adjustable output with a 0.9V to 5V output range.
• Single-output linear regulator delivering up to 2A.
• Input voltage rating up to 6.5V.
• Maximum dropout voltage of 0.625V at 2A.
• Enable control for output activation or shutdown.
• Integrated over-current and over-temperature protection.
• Operating temperature range of -40°C to 125°C.
• Surface-mount S-PAK-5 package with five leads plus a tab.

Applications

• Point-of-load regulation for embedded control boards that require a positive adjustable rail from an input source up to 6.5V.
• Adjustable power rails for logic, analog, or mixed-signal circuitry within the 0.9V to 5V output range.
• Controlled activation or shutdown of power rails in embedded systems using the enable function.

Design & Procurement Notes

Designers should set the output within the 0.9V to 5V adjustable range and keep the input voltage at or below 6.5V. At 2A load current, allow at least 0.625V of input-to-output headroom to account for the maximum dropout voltage. The enable control can be used for system sequencing or controlled shutdown, while over-current and over-temperature protection should be considered as part of the power-stage fault strategy. The S-PAK-5 package includes a tab, so the PCB footprint and thermal layout should be planned around the package and the -40°C to 125°C operating range. Use the exact part number MIC49200WR and package designation S-PAK-5 in design and procurement documentation.
