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.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
