Frequently Asked Questions
Can the MIC5323-3.3YD5 TR power a 3.3 V microcontroller directly from a single Li-ion cell at 3.7 V nominal?
Yes. The MIC5323-3.3YD5 TR accepts input voltages from 2.65 V to 5.5 V, so a Li-ion cell ranging from about 3.0 V (depleted) to 4.2 V (fully charged) falls within its operating range. The LDO maintains a stable 3.3 V ±2% output at up to 300 mA, making it a reliable power source for 3.3 V microcontrollers and wireless modules.
What output current does the MIC5323-3.3YD5 TR deliver and which load types is it designed for?
The MIC5323-3.3YD5 TR is rated for a maximum output current of 300 mA at 3.3 V. This current level is sufficient to power low-power microcontrollers, Bluetooth SoCs, environmental sensors, and small RF modules. Loads exceeding 300 mA should use a higher-current LDO or DC-DC converter to avoid overloading the regulator.
How does the TSOT-23 5-pin package of the MIC5323-3.3YD5 TR compare to standard SOT-23 in board space?
The TSOT-23 5-pin package has a body measuring approximately 1.6 mm x 1.0 mm, which is smaller than the standard SOT-23-3 footprint. This ultra-compact size is ideal for wearable devices, hearing aids, and IoT modules where every square millimeter of PCB space matters, while the 5 pins still allow for enable and bypass functionality.
For a high-volume IoT module BOM, how does the tape-and-reel packaging of the MIC5323-3.3YD5 TR support production?
The TR suffix on MIC5323-3.3YD5 TR indicates tape-and-reel packaging, which is the standard format for automated SMT pick-and-place assembly lines. Tape-and-reel packaging typically comes in reels of 3000 or more units, reducing component handling time and supporting continuous high-volume PCB production without manual feeder changes.
