Frequently Asked Questions
What is the maximum output current of MIC5365-3.3YD5 T5 and which load scenarios is it designed for?
MIC5365-3.3YD5 T5 can supply up to 150 mA output current at 3.3 V. This capacity covers microcontrollers, Bluetooth modules, and small sensor arrays in IoT designs. It is not suited for loads exceeding 150 mA without additional parallel regulators or a step-down switcher.
Can MIC5365-3.3YD5 T5 be powered directly from a single-cell Li-ion battery as it discharges?
Yes. The input range of 2.5 V to 5.5 V means MIC5365-3.3YD5 T5 continues to regulate 3.3 V even as a 3.7 V nominal Li-ion cell discharges toward 2.7 V near depletion. This allows firmware to operate until the battery protection circuit cuts off at approximately 2.5 V.
How does the output accuracy of ±3% affect digital circuits supplied by MIC5365-3.3YD5 T5?
The ±3% output accuracy means the regulated output stays between approximately 3.20 V and 3.40 V over temperature and load. Most 3.3 V logic devices, including MCUs and FPGAs, tolerate a ±5% or ±10% supply range, so the ±3% tolerance of this LDO comfortably meets digital component supply requirements.
What package does MIC5365-3.3YD5 T5 use and how does it benefit space-constrained PCB layouts?
MIC5365-3.3YD5 T5 comes in a 5-pin TSOT-23 package, one of the smallest SOT footprints available. The tiny body dimensions of approximately 2.9 mm × 1.6 mm allow placement adjacent to the load IC, reducing decoupling trace lengths and improving transient response on densely populated boards.
