Frequently Asked Questions
What is the output current capability of MIC5247-1.8YML TR and what input voltage range does it accept?
MIC5247-1.8YML TR delivers up to 150 mA of regulated 1.8 V output current and accepts input voltages from approximately 2.5 V to 5.5 V, covering standard 3.3 V, 5 V, and single-cell Li-ion battery supply rails used in portable embedded systems.
For a battery-powered IoT sensor running at 1.8 V, how efficient is MIC5247-1.8YML TR compared to a 3.3 V LDO?
Powering a 1.8 V load directly from a 3.3 V bus with MIC5247-1.8YML TR reduces the input-to-output voltage difference to roughly 1.5 V at 150 mA, limiting quiescent dissipation to 225 mW maximum. A 3.3 V LDO in the same position would deliver the wrong voltage, confirming that MIC5247-1.8YML TR is the correct first-stage regulator for 1.8 V subsystems in IoT nodes.
How does the exposed pad on the DFN-EP package of MIC5247-1.8YML TR affect PCB thermal design?
The exposed thermal pad on the 6-pin DFN-EP package allows direct solder bonding to the PCB ground plane, providing a low thermal resistance path of approximately 40°C/W junction-to-board. This enables MIC5247-1.8YML TR to sustain 150 mA output without heatsinking on a standard 2-layer PCB, even in ambient temperatures up to 70°C.
