MIC826TYMT-TR: A 1.5A, 28V, High-Efficiency µCap LDO Voltage Regulator from Microchip

In the realm of power management, delivering clean, stable, and efficient voltage to sensitive circuits is a fundamental challenge. The MIC826TYMT-TR from Microchip Technology emerges as a powerful solution, redefining the capabilities of low-dropout (LDO) regulators. This component is engineered to provide a robust 1.5A output current from an input voltage as high as 28V, all while maintaining exceptional efficiency and stability with minimal external components.

A standout feature of the MIC826TYMT-TR is its µCap (micro-capacitor) design. Unlike traditional LDOs that require large, expensive electrolytic capacitors for stability, this regulator is specifically designed to remain stable with a tiny, low-ESR ceramic output capacitor as small as 1µF. This drastically saves valuable board space, reduces overall solution cost, and enhances reliability by removing failure-prone electrolytic caps. The incredibly low dropout voltage—as low as 190mV at 1A—ensures high efficiency even when the input voltage is only marginally higher than the output, preserving battery life in portable applications.

The device's high input voltage tolerance of up to 28V offers significant design flexibility, making it suitable for a wide array of applications. It is particularly ideal for powering core voltages in 12V and 24V industrial systems, automotive infotainment, and networking equipment, where it can efficiently step down higher rail voltages to lower levels required by processors, FPGAs, and ASICs. Its high PSRR (Power Supply Rejection Ratio) and excellent line/load transient response ensure a quiet, stable output, immune to noise from noisy input sources.

Built with robustness in mind, the MIC826TYMT-RR includes comprehensive protection features such as internal current limiting and thermal shutdown, safeguarding both the regulator and the load under fault conditions. Housed in a space-saving 8-pin 2x2 TDFN package, it is perfect for modern, compact electronic designs.

ICGOOODFIND: The MIC826TYMT-TR is a superior choice for designers seeking a high-current, high-input-voltage LDO that doesn’t compromise on efficiency or board space. Its µCap capability, impressive electrical characteristics, and robust feature set make it an exceptionally reliable and compact power management solution for demanding industrial and automotive environments.
