Frequently Asked Questions
What is the maximum output current the MIC5504-3.3YM5 TR can supply continuously?
The MIC5504-3.3YM5 TR is rated for a maximum continuous output current of 300 mA. This is sufficient for powering microcontrollers, sensors, and small RF modules in battery-powered designs operating from a 3.3 V rail.
How does the SOT-23-5 package benefit compact PCB designs using MIC5504-3.3YM5 TR?
The SOT-23-5 package measures approximately 2.9 mm x 1.6 mm, making it one of the smallest 5-pin surface-mount packages available. This tiny footprint allows designers to place the regulator very close to load components, reducing trace inductance and supporting high-density board layouts with less than 10 mm² board area required.
When is the MIC5504-3.3YM5 TR preferred over a switching regulator for powering analog or RF circuits?
The MIC5504-3.3YM5 TR is preferred when output ripple must stay below a few millivolts and switching noise would degrade analog or RF performance. Its linear regulation architecture eliminates the switching harmonics inherent to DC-DC converters, and its high PSRR — typically greater than 60 dB at 1 kHz — makes it ideal for noise-sensitive loads such as ADC reference supplies, PLLs, and low-noise amplifiers running at 3.3 V.
What input voltage range is required to operate the MIC5504-3.3YM5 TR with a 3.3 V output?
The MIC5504-3.3YM5 TR requires a minimum input voltage of approximately 3.6 V (accounting for dropout voltage) and supports inputs up to 6 V. For typical applications powered by a single Li-ion cell providing 3.7 V to 4.2 V, the device comfortably maintains a stable 3.3 V output across the full battery discharge range.
