MIC5375 Datasheet, PDF (1/18 Pages) Micrel Semiconductor – High Performance Low Dropout 150mA LDO

MIC5375/6/7/8
High Performance Low Dropout 150mA LDO
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^® package while the MIC5377/8 provides
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^® and SC-70-5. The MIC5377/8 is
available in lead-free (RoHS compliant) 1.2mm x 1.2mm
Thin MLF^® and SC-70-5.
The MIC5375/6/7/8 has an operating junction temperature
range of –40°C to 125°C.
