Functional Features

• Voltage Regulation: The MIC5265-2.85YD5-TR provides a stable output voltage of 2.85V, regardless of variations in the input voltage or load conditions.
• Low Quiescent Current: With a typical quiescent current of only 40µA, this regulator minimizes power consumption when not actively supplying current to the load.
• Shutdown Mode: By pulling the Enable (EN) pin low, the regulator enters a low-power shutdown mode, reducing current consumption to a mere 0.1µA.
• Thermal Shutdown Protection: The device incorporates thermal shutdown protection, which prevents damage due to excessive heat by shutting down the regulator temporarily until the temperature returns to a safe level.

Advantages and Disadvantages

Advantages

• Wide input voltage range allows for compatibility with various power sources.
• Low dropout voltage ensures efficient regulation even with small input-output voltage differentials.
• Low quiescent and shutdown currents contribute to overall power efficiency.
• Thermal shutdown protection enhances reliability and safeguards against overheating.

Disadvantages

• Limited maximum output current of 150mA may not be suitable for high-power applications.
• The SOT-23-5 package may require additional care during soldering due to its small size.

Working Principles
