MIC47050YML-TR

Product Overview

The MIC47050YML-TR from Microchip Technology is a positive adjustable linear voltage regulator for single-output low-voltage regulation in surface-mount designs. The device supports up to 500mA output current, an adjustable output from 0.4V to 2V, and a maximum input voltage of 3.6V. The dropout voltage is 0.12V at 500mA, and the package is a 6-DFN (2x2) surface-mount package with an exposed pad. The regulator includes enable and power-good control features, over-temperature protection, and under-voltage lockout, with an operating temperature range of -40°C to 85°C.

Key Features

• Single positive adjustable output with a 0.4V to 2V output range and 500mA output current.
• Low dropout voltage of 0.12V at 500mA and 15µA quiescent current.
• Enable and power-good control features for managed power sequencing and status indication.
• Over-temperature protection and under-voltage lockout are included as protection features.
• 6-VDFN exposed pad, 6-MLF surface-mount package, 6-DFN (2x2).
• Power-supply ripple rejection of 50dB to 37dB over 10kHz to 100kHz.

Applications

• Regulating a low-voltage digital rail within the 0.4V to 2V output range for compact surface-mount boards.
• Providing enabled power to downstream circuits that require a power-good status signal.
• Maintaining a regulated output at up to 500mA in space-constrained equipment operating from -40°C to 85°C.

Design & Procurement Notes

When selecting the MIC47050YML-TR, confirm that the available input voltage remains within the 3.6V maximum and that the input-output difference satisfies the 0.12V dropout at the intended load current. Set the output within the 0.4V to 2V adjustable range and verify that the relevant ripple frequency falls within the 10kHz to 100kHz PSRR range. Use the enable and power-good functions according to the system power-management requirements, and consider thermal pad soldering and board heat dissipation because the device is surface mounted in a 2x2 package and operates from -40°C to 85°C.
