MIC5311 - LowQ Mode Dual 300mA LDO

Datasheet Summary

Description

The MIC5311 is a high performance, dual µCap low dropout regulator offering ultra-low operating current and a second, even lower operating current mode, LowQ™ mode, reducing operating current by 75%.

Each regulator can source up to 300mA of output current maximum.

Features

  • Input voltage range: 2.5V to 5.5V.
  • LowQ™ Mode - 7µA total quiescent current - 10mA output current capable LowQ™ mode - Logic level control with external pin.
  • Stable with ceramic output capacitor.
  • 2 LDO Outputs.
  • 300mA each.
  • Tiny 3mm x 3mm MLF™-10 package.
  • Low dropout voltage of 60mV @ 150mA.
  • Ultra-low quiescent current of 28µA total in Full Current Mode.
  • High output accuracy - ±1.0% initial accuracy - ±2.0% over tem.

MIC5311 LowQ™ Mode Dual 300mA LDO General Description The MIC5311 is a high performance, dual µCap low dropout regulator offering ultra-low operating current and a second, even lower operating current mode, LowQ™ mode, reducing operating current by 75%. Each regulator can source up to 300mA of output current maximum. Ideal for battery operated applications, the MIC5311 offers 1% accuracy, extremely low dropout voltage (60mV @ 150mA), and low ground current (typically 28µA total). When put into LowQ™ mode, the internal current draw drops down to 7µA total. The MIC5311 also comes equipped with a TTL logic compatible enable pin that allows the part to be put into a zero-offmode current state, drawing no current when disabled.
