MIC94325YMT-TR

Product Overview

The Microchip Technology MIC94325YMT-TR is a single-output, positive adjustable linear voltage regulator for compact power-management designs. It delivers up to 500 mA with an adjustable output from 1.2 V to 3.4 V and a maximum input rating of 3.6 V. The device uses a 6-UFDFN exposed-pad package, 6-TDFN (1.6 mm x 1.6 mm), and includes an enable control for selective output operation.

Key Features

• Positive adjustable output with one regulator and 500 mA output current
• Output range from 1.2 V to 3.4 V with maximum input of 3.6 V
• Maximum dropout of 0.2 V at 500 mA and 250 µA quiescent current
• Power-supply ripple rejection of 85 dB to 50 dB from 100 Hz to 5 MHz
• Enable control with overcurrent and overtemperature protection
• Surface-mount 6-UFDFN exposed-pad package, 6-TDFN (1.6 mm x 1.6 mm), rated -40°C to 125°C

Applications

• Regulated low-voltage rails for microcontrollers and digital logic
• Biasing for analog sensors and mixed-signal front ends
• Selective power delivery to subsystems that require an adjustable positive output and enable control
• Low-voltage peripheral circuits in compact electronics using a 1.6 mm x 1.6 mm exposed-pad regulator

Design & Procurement Notes

Designers should verify that the input supply remains within the 3.6 V maximum and that the selected output voltage maintains adequate headroom above the 1.2 V to 3.4 V adjustable range, especially near the 0.2 V dropout limit at 500 mA. The 250 µA quiescent current and 85 dB to 50 dB ripple rejection from 100 Hz to 5 MHz are relevant for low-power and noise-sensitive loads. The enable control allows the output to be enabled or disabled. The device is specified for operation from -40°C to 125°C and includes overcurrent and overtemperature protection. For layout, account for the 6-UFDFN exposed-pad package and its 1.6 mm x 1.6 mm footprint during PCB design.
