General Description
The MIC5376, MIC5377, and MIC5378 are advanced,
general purpose linear regulators that offer low dropout
in ultra-small packages. The MIC5376 provides a fixed
output voltage in a 1 mm x 1 mm UDFN package while
the MIC5377 and MIC5378 provide adjustable output
voltages in a 1.2mm x 1.2 mm Thin QFN package.
When the MIC5376 or MIC5378 are disabled, an
internal resistive load is automatically applied to the
output to discharge the output capacitor. The
MIC5376/7/8 are capable of sourcing 150 mA output
current with low dropout, making it an ideal solution for
any portable electronic application.
Ideal for battery-powered applications, the
MIC5376/7/8 offer 2% initial accuracy, low dropout
voltage (120 mV at 150mA), and ground current
(typically 29 µA). The MIC5376/7/8 can also be put into
a zero-off-mode current state, drawing virtually no
current when disabled.
The MIC5376 is available in lead-free (RoHS
compliant) 1 mm x 1 mm UDFN and SC-70-5
packages. The MIC5377/8 are available in lead-free
(RoHS compliant) 1.2 mm x 1.2mm Thin QFN and
SC-70-5 packages.
The MIC5376/7/8 have an operating junction
temperature range of –40°C to 125°C.
