Applications
The MIC5282-3.3YMM TR is designed for powering 3.3 V digital logic, wireless modules, and sensor interfaces in portable consumer electronics and IoT devices. Its low dropout characteristic allows operation from Li-Ion or two-cell alkaline batteries as they discharge toward end-of-life voltages below 4 V. The TSOT-23-5 form factor is well suited for compact wearables, Bluetooth accessories, and handheld instruments requiring a stable 3.3 V rail.

Frequently Asked Questions
What output voltage and current does the MIC5282-3.3YMM TR provide for a typical 3.3 V system rail?
The MIC5282-3.3YMM TR provides a fixed 3.3 V output at up to 150 mA, making it appropriate for powering microcontrollers, BLE SoCs, and low-power sensors. Its fixed output removes the need for external resistor dividers, reducing component count and simplifying PCB layout in cost-sensitive battery-powered designs.
How does the MIC5282-3.3YMM TR perform in battery-powered IoT applications where input voltage drops as the cell discharges?
Because the MIC5282-3.3YMM TR is a low-dropout regulator, it maintains a regulated 3.3 V output even when the input voltage drops to just above 3.3 V — typically within a few hundred millivolts dropout. This allows the device to squeeze additional operating time from lithium or alkaline cells compared to standard LDOs, extending useful runtime before the battery is considered depleted.
What package does the MIC5282-3.3YMM TR use, and how does that affect board-space planning?
The MIC5282-3.3YMM TR is housed in a TSOT-23-5 package, which measures approximately 2.9 mm × 1.6 mm — one of the smallest 5-pin SOT footprints available. Designers working on wearable devices, wireless sensor nodes, or Bluetooth dongles can place it in tight PCB areas without compromising the 150 mA current delivery needed for active-mode operation.
