MAQ5300
Automotive Qualified Single Output 300mA
µCap LDO
General Description
The MAQ5300 is an automotive-qualified, ultra-small,
ultra-low dropout CMOS regulator (ULDO) that is ideal for
today’s most demanding automotive applications including
infotainment, camera module, image sensors, and
anywhere PCB space is limited. It offers extremely low
dropout voltage, very low output noise and can operate
from a 2.3V to 5.5V input while delivering up to 300mA.
The MAQ5300 offers 2% initial accuracy, low ground
current (typically 85µA total), thermal shutdown, and
current-limit protection. The MAQ5300 can also be put into
a zero-off-mode current state, drawing no current when
disabled.
The MAQ5300’s operating junction temperature range is
–40°C to +125°C and it is available in fixed output voltages
in a lead-free (RoHS-compliant) 6-pin 2mm × 2mm DFN
package.
Datasheets and support documentation are available on
Micrel’s website at: www.micrel.com.
