General Description

The MIC5375/6/7/8 is an advanced general purpose linear

regulator offering low dropout in an ultra small package.

The MIC5375/6 provides fixed output voltage in a 1mm x

1mm Thin MLF

adjustable output voltage in a 1.2mm x 1.2mm Thin MLF

®

package. When the MIC5376/8 is disabled an internal

resistive load is automatically applied to the output to

discharge the output capacitor. The MIC5375/6/7/8 is

capable of sourcing 150mA output current with low dropout

making it an ideal solution for any portable electronic

application.

Ideal for battery powered applications, the MIC5375/6/7/8

offers 2% initial accuracy, low dropout voltage (120mV at

150mA), and ground current (typically 29µA). The

MIC5375/6/7/8 can also be put into a zero-off-mode

current state, drawing virtually no current when disabled.

The MIC5375/6 is available in lead-free (RoHS compliant)

1mm x 1mm Thin MLF

available in lead-free (RoHS compliant) 1.2mm x 1.2mm

Thin MLF

The MIC5375/6/7/8 has an operating junction temperature

range of –40°C to 125°C.
