MIC5381

www.DataSheet4U.com MIC5380/1 High Performance Dual 150mA LDO 1mm x 1mm Thin MLF® General Description The MIC5380/1 is an advanced dual LDO ideal for powering space constrained portable devices. The MIC5380/1 provides two independently controlled, high performance 150mA LDOs in an ultra small 1mm x 1mm ® Thin MLF package. Ideal for battery powered applications, the MIC5380/1 offers ±1% typical accuracy, low dropout voltage (155mV at 150mA) and low ground current. The MIC5380/1 can also be put into a zero-off-mode current state, drawing virtually no current when disabled. The MIC5380/1 offers fast transient response and high PSRR while consuming minimal operating current. When the MIC5381 is disabled an internal resistive load is automatically applied to the output to discharge the output capacitor. The MIC5380/1 is available with fixed output voltages in a ® lead-free (RoHS compliant) 6-pin 1mm x 1mm Thin MLF package.
