Frequently Asked Questions
What maximum output current can MIC5219YM5 TR supply continuously?
The MIC5219YM5 TR is rated for a maximum continuous output current of 500 mA, making it suitable for powering microcontrollers, wireless modules, and other moderate-load circuits from a single compact SOT-23-5 regulator without external power transistors.
How accurate is the output voltage regulation of MIC5219YM5 TR over temperature?
The MIC5219YM5 TR achieves ±1% output voltage accuracy across its operating temperature range, which is critical for analog signal chains, ADC reference supplies, and precision sensor biasing where tight voltage tolerance directly impacts measurement accuracy.
Which battery-powered application designs benefit most from the MIC5219YM5 TR at 3.3 V output from a 3.6 V Li-ion cell?
IoT sensor nodes, Bluetooth Low Energy modules, and portable medical instruments operating from a 3.6 V Li-ion cell benefit most, because the low dropout voltage of the MIC5219YM5 TR allows it to maintain a regulated 3.3 V output even as the cell discharges below 3.5 V, maximizing usable battery runtime.
Is MIC5219YM5 TR a lower-cost or smaller-footprint alternative to larger LDO packages for 500 mA loads?
Yes, the SOT-23-5 package of MIC5219YM5 TR occupies roughly 2.9 mm x 1.6 mm of board area, providing a significantly smaller footprint than SOT-89 or TO-252 regulators at the same 500 mA rating, reducing BOM cost and PCB area for space-constrained designs.
