What are the key features of MIC5528-3.3YMT TR?
- 500 mA output current capability with low dropout voltage, enabling efficient 3.3 V regulation from a 3.5 V or higher input rail
- Ultra-compact 6-pin TDFN package minimizes board footprint for density-critical wearable and IoT power designs
- Low quiescent current operation extends battery life in always-on sensor nodes and portable consumer electronics
What is MIC5528-3.3YMT TR used for?
The MIC5528-3.3YMT TR provides a stable 3.3 V rail for microcontrollers, wireless modules, and memory devices in battery-powered IoT nodes, wearables, and handheld consumer products. Its compact TDFN-6 package and 500 mA current rating make it ideal for small form-factor PCBs where board area is at a premium. It also serves as a post-regulator after a switching converter to suppress output ripple and provide a clean 3.3 V supply for noise-sensitive analog and RF circuits.

Frequently Asked Questions
What is the output voltage and maximum current rating of MIC5528-3.3YMT TR?
The MIC5528-3.3YMT TR provides a fixed 3.3 V output at up to 500 mA continuous output current. The TDFN-6 package allows for good thermal dissipation relative to its small footprint, supporting the full 500 mA load in most PCB layouts with adequate copper pours, making it suitable for powering 3.3 V microcontrollers and wireless transceivers.
How does the TDFN-6 package of MIC5528-3.3YMT TR benefit space-constrained IoT designs?
The 6-pin TDFN package of MIC5528-3.3YMT TR occupies a very small PCB footprint of approximately 2 mm x 2 mm, which is critical for wearable devices, sensor patches, and compact IoT modules where every square millimeter of board space is valuable. The exposed thermal pad on the bottom of the package also improves heat transfer for 500 mA loads compared to traditional SOT-23 or SOIC packages of similar pin count.
When should MIC5528-3.3YMT TR be used as a post-regulator after a DC-DC buck converter?
MIC5528-3.3YMT TR is a practical post-regulator when a buck converter's switching ripple exceeds 10 mV and downstream analog or RF circuits require a clean 3.3 V supply. Its LDO architecture adds only a small voltage drop while attenuating high-frequency noise by typically 40 dB or more, and its 500 mA rating covers the combined current of a Bluetooth SoC, an MCU, and associated sensors running simultaneously.
