Description

The MIC5380/1 is an advanced dual LDO ideal for powering space constrained portable devices. 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.
