Micrel: MAQ5300: 300mA, AEC-Q100-Compliant LDO for Automotive Applications

AC_MIC_maq5300prfinalmicrel-logo
The MAQ5300 is a new automotive AEC-Q100 qualified high performance low-dropout voltage regulator (LDO) featuring an ultra-low dropout of only 100mV at 300mA. The MAQ5300 comes in a tiny 2 x 2mm DFN package and is ideal for space-constrained and high- reliability applications that are subjected to the harsh environments and temperatures often encountered in automotive and industrial applications. It 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.
