MIC47050-1.2YML-TR

Product Overview

The MIC47050-1.2YML-TR from Microchip Technology is a positive fixed-output linear voltage regulator intended for single-rail supply conversion. The device provides a 1.2V output at up to 500mA, with a maximum input voltage of 3.6V and a maximum dropout of 0.12V at the rated output current. It uses a 6-DFN (2x2) surface-mount package with an exposed pad, supporting compact power distribution in compact electronic assemblies.

Key Features

• Fixed 1.2V positive output from a single regulator channel.
• 500mA output current with 0.12V maximum dropout at 500mA.
• Maximum input voltage of 3.6V and 15 µA quiescent current.
• Power supply rejection ratio of 50dB to 37dB from 10kHz to 100kHz.
• Enable and Power Good control features.
• Over Temperature and Under Voltage Lockout (UVLO) protection features.
• Operating temperature range of -40°C to 85°C.
• 6-DFN (2x2) surface-mount package with exposed pad.

Applications

• Providing a fixed 1.2V rail for low-voltage digital loads in compact electronic assemblies.
• Supplying 1.2V to sensors, logic, or interface circuitry in embedded control boards.
• Forming an enable-controlled power domain for sequencing in multi-rail system boards.
• Delivering a monitored 1.2V supply where Power Good status supports system supervision.

Design & Procurement Notes

When selecting this regulator, verify that the available input voltage remains at or below 3.6V while providing sufficient headroom above 1.2V for the required load current. The 0.12V maximum dropout at 500mA should be considered against input-voltage variations and board losses. The exposed-pad 6-DFN package supports surface-mount layout, and the operating temperature range of -40°C to 85°C should be checked against the final assembly environment. Enable and Power Good can be used for power sequencing and status monitoring, while over-temperature and UVLO protection should be incorporated into system-level power management planning.
