Features & Applications

The MIC5239YM is a low quiescent current, µCap low-dropout regulator. With a maximum operating input voltage of 30 V and a quiescent current of 23 µA, it is ideal for supplying keep-alive power in systems with high voltage batteries. Capable of 500 mA output, the MIC5239 has a dropout voltage of only 350 mV. It can provide high output current for applications such as USB.

As a µCap LDO, the MIC5239 is stable with either a ceramic or a tantalum output capacitor. It only requires a 3.3 µF output capacitor for stability. The MIC5239 includes a logic compatible enable input and an under voltage error flag indicator. Other features of the MIC5239 include thermal shutdown, current limit, over voltage shutdown, reverse-leakage protection, and reverse-battery protection. Available in the thermally enhanced SOIC-8, MSOP-8 and SOT-223, the MIC5239 comes in fixed 3.0 V and adjustable voltages.

Features:

  • Ultra-low quiescent current (IQ = 23 µA @IO = 100 µA)
  • Continuious 500 mA output current
  • Wide input range: 2.3 V to 30 V
  • Low dropout voltage:
  • 350 mV @500 mA;
  • ±1.0% initial output accuracy
