Frequently Asked Questions
What is the output voltage and maximum load current of MIC69101-1.8?
MIC69101-1.8 provides a fixed 1.8 V regulated output and can supply up to 1 A continuous load current. This combination makes it directly suitable for powering 1.8 V DDR memory, low-power FPGAs, and mixed-signal processor cores without requiring external feedback resistors.
How does the MLF 3×3 mm package of MIC69101-1.8 compare to SOT-223 alternatives for space-constrained designs?
The 10-pin MLF 3×3 mm package of MIC69101-1.8 occupies roughly 9 mm² of PCB area, compared to approximately 25 mm² for a SOT-223 package. The smaller footprint and exposed thermal pad improve heat dissipation through the PCB, reducing junction temperature rise by 15°C to 20°C at 1 A load in typical 2-layer board designs.
For which IoT or wearable applications is MIC69101-1.8 best suited?
MIC69101-1.8 is ideal for IoT sensor nodes, Bluetooth Low Energy modules, and smartwatch subsystems that require a stable 1.8 V rail below 1 A. Its low quiescent current and compact MLF package suit always-on sensor hubs where the regulator must maintain 1.8 V output while keeping idle supply current below a few milliamps to extend coin-cell battery life.
Does MIC69101-1.8 require external capacitors, and what values are recommended?
MIC69101-1.8 requires a minimum 1 µF ceramic input bypass capacitor and a 10 µF ceramic output capacitor for stable operation. Using X5R or X7R capacitors with ESR below 100 mΩ ensures loop stability and minimizes output voltage ripple below 10 mV at full 1 A load, which is critical for noise-sensitive analog and RF supply rails.
