General Description

The MIC5370/1 is an advanced dual LDO ideal for

powering general purpose portable devices. The

MIC5370/1 provides two independently-controlled, high-

performance 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.
