MIC5365/6
High Performance Single 150mA LDO
General Description
The MIC5365/6 is an advanced general purpose linear
regulator offering high power supply rejection (PSRR) in
an ultra-small 1mm x 1mm package. The MIC5366
includes an auto-discharge feature that is activated when
the enable pin is low. The MIC5365/6 is capable of
sourcing 150mA output current and offers high PSRR
making it an ideal solution for any portable electronic
application.
Ideal for battery powered applications, the MIC5365/6
offers 2% initial accuracy, low dropout voltage (155mV @
150mA), and low ground current (typically 29µA). The
MIC5365/6 can also be put into a zero-off-mode current
state, drawing virtually no current when disabled.
The MIC5365/6 is available in several advanced packages
including a lead-free (RoHS compliant) 1mm x 1mm Thin
MLF
®
occupying only 1mm
2
of PCB area, a 75% reduction
in board area compared to SC-70 and 2mm x 2mm MLF
®
packages. It is also availabe in an SC-70-5 package.
The MIC5365/6 has an operating junction temperature
range of –40°C to 125°C.
