MIC5236-5.0YM-TR: Powering Modern Electronics with Ultra-Low Quiescent Current

In the realm of portable and battery-powered electronics, power management is paramount. Every microamp of current saved translates directly to extended battery life and enhanced product performance. The MIC5236-5.0YM-TR from Microchip Technology stands out as a critical component in this pursuit, offering a robust and highly efficient 5.0V, 150mA low-dropout (LDO) voltage regulator solution.

This regulator is engineered to provide a stable and clean 5.0V output from an input voltage range of 2.7V to 16V, making it exceptionally versatile for a wide array of applications. Its core strength lies in its remarkably low quiescent current (Iq), typically just 1.6µA. This is the current the device consumes internally when it is active but not supplying significant load current. For devices spending long periods in standby or sleep modes, such as IoT sensors, wearable health monitors, or handheld remote controls, this ultra-low Iq is a game-changer. It ensures that the battery is not drained by the power management circuitry itself, thereby maximizing operational lifetime.

Beyond its quiescent performance, the MIC5236-5.0YM-TR boasts an impressively low dropout voltage. It can maintain a regulated 5.0V output even when the input voltage dips to just 5.1V, ensuring stable operation as battery voltage decays. The device also incorporates essential protection features, including current limiting and thermal shutdown, safeguarding both the regulator and the downstream components from fault conditions. Its minimal external component requirement—often just a single input and output capacitor—simplifies design and reduces both board space and the total bill of materials (BOM).

Housed in a space-saving SOT-23-5 package, this LDO is ideal for compact, modern electronic designs where every square millimeter counts.

ICGOODFIND: The MIC5236-5.0YM-TR is an optimal choice for designers seeking a simple, reliable, and highly efficient 5V power solution. Its combination of ultra-low quiescent current, low dropout voltage, and integrated protection makes it a superior component for extending battery life in power-sensitive portable and wireless applications.
