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.
