MIC5389 - Dual 200mA Peak LDO

Download the MIC5389 datasheet PDF. This datasheet also covers the MIC5388 variant, as both devices belong to the same dual 200ma peak ldo family and are provided as variant models within a single manufacturer datasheet.

General Description

The MIC5388/9 is an advanced dual LDO ideal for powering general purpose portable devices.

The MIC5388/9 provides two independently-controlled, highperformance, 200mA peak (150mA continuous) LDOs in a miniature 6-bump, 0.5mm pitch, 1.5mm × 1.0mm wafer level chip scale package (WLCSP).

Key Features

  • 2.5V to 5.5V input voltage range.
  • Two 200mA peak output current LDOs.
  • High output accuracy (±2%).
  • Low quiescent current (32µA per LDO).
  • Stable with 1µF ceramic output capacitors.
  • Low dropout voltage (175mV at 150mA).
  • Independent enable pins.
  • Output discharge circuit (MIC5389).
  • Thermal-shutdown protection.
  • Current-limit protection.
  • 6-bump 1.5mm × 1.0mm WLCSP package.

MIC5388/9 Dual 200mA Peak LDO in Wafer Level Chip Scale Package General Description The MIC5388/9 is an advanced dual LDO ideal for powering general purpose portable devices. The MIC5388/9 provides two independently-controlled, highperformance, 200mA peak (150mA continuous) LDOs in a miniature 6-bump, 0.5mm pitch, 1.5mm × 1.0mm wafer level chip scale package (WLCSP). Ideal for battery-powered applications, the MIC5388/9 offers 2% accuracy, low dropout voltage (175mV @ 150mA) and low ground current (typically 32μA per LDO). The MIC5388/9 can also be put into a zero off mode current state, drawing virtually no current when disabled. When the MIC5389 is disabled an internal resistive load is automatically applied to the output to discharge the output capacitor.
