MIC5370

MIC5370/1 High-Performance Dual 150mA LDO 1.6mm x 1.6mm Thin MLF® General Description The MIC5370/1 is an advanced dual LDO ideal for powering general purpose portable devices. The MIC5370/1 provides two independently-controlled, highperformance 150mA LDOs in a tiny 1.6mm x 1.6mm Thin MLF® package. Ideal for battery-powered applications, the MIC5370/1 offers 2% initial accuracy, low dropout voltage (155mV @ 150mA) and low ground current (typically 32μA per LDO). The MIC5370/1 can also be put into a zero-off-mode current state, drawing virtually no current when disabled. When the MIC5371 is disabled an internal resistive load is automatically applied to the output to discharge the output capacitor. This LDO offers fast transient response and high PSRR while consuming a minimum operating current. The MIC5370/1 is available in fixed output voltages in a lead-free (RoHS-compliant) 6-pin 1.6mm x 1.6mm Thin MLF® package.
