The MIC2876-0YMT-T5: Powering the Next Generation of Always-On Applications

In an era where electronic devices are increasingly required to be always listening, sensing, and communicating, the demand for efficient, always-on power management has never been higher. The Microchip MIC2876-0YMT-T5 stands out as a critical component designed specifically to meet this challenge. This 150mA low-dropout (LDO) voltage regulator combines ultra-low quiescent current (Iq) with excellent transient performance, making it an ideal power solution for battery-powered and space-constrained applications.

The defining feature of the MIC2876 is its remarkably low quiescent current of just 450nA (typical). Quiescent current is the power the regulator consumes by itself to maintain operation when no load current is being drawn. In applications like IoT sensor nodes, wearables, and hearing aids, the device spends a significant amount of time in a sleep or standby mode. A traditional LDO, with a quiescent current in the tens or hundreds of microamps, would quickly drain the battery in these states. The MIC2876's nanoamp-level Iq dramatically extends battery life by minimizing wasted energy during these long periods of inactivity.

Despite its ultra-lean power footprint, the MIC2876 does not compromise on performance. It provides a solid 150mA output current with a low dropout voltage of 180mV at 100mA load. This ensures a stable and regulated voltage supply even as the battery voltage decays towards the regulator's output voltage, allowing every last bit of energy to be utilized from the battery. Furthermore, it features excellent line and load regulation, ensuring a clean and stable output for sensitive analog and digital circuits.

The device is offered in a fixed output voltage range from 1.2V to 5.0V, with the specific voltage denoted by the part number suffix. Housed in a tiny 1.0mm x 1.5mm 6-pin MST package, it is perfectly suited for designs where printed circuit board (PCB) real estate is at a premium. Additional built-in protections, including current limit and thermal shutdown, enhance the reliability of the end product.

Typical applications that benefit from the MIC2876-0YMT-T5 include:

Internet of Things (IoT) sensors and modules

Wearable health and fitness devices

Bluetooth Low Energy (BLE) accessories

Portable medical and diagnostic equipment

Always-on system monitoring and real-time clocks (RTCs)

ICGOODFIND: The Microchip MIC2876-0YMT-T5 is a pinnacle of efficiency for modern power design. Its unparalleled combination of ultra-low Iq, robust 150mA output, and miniature form factor makes it an indispensable solution for designers striving to maximize runtime and minimize size in their next-generation portable and always-on products.
