Diodes Incorporated’s new AP7347DQ low dropout (LDO) voltage regulator is optimized for noise-sensitive power-related automotive applications. This automotive-compliant high output accuracy LDO is AEC-Q100 Grade 1 qualified, manufactured in IATF 16949 certified facilities and supports automotive production part approval processes (PPAPs). 

Applications include ADAS, automotive wireless communication systems, RF subsystems, and infotainment power sources.

A 75dB power supply rejection ratio (PSRR), combined with an output noise of just 60µVrms, gives the AP7347DQ performance advantages. It is available in 12 fixed output voltage variants with a ±1 per cent voltage-output accuracy, which is maintained across its entire -40 to 125°C operational temperature range. Its 1.7 to 5.5V input voltage range gives it the versatility to address numerous automotive application requirements, while its 60µA quiescent current mitigates standby power losses.
