The new automotive-compliant, high-output accuracy LDO is AEC-Q100 Grade 1 qualified, manufactured in IATF 16949 certified facilities, and fully supports automotive production part approval processes.
These qualities make it well-suited to design in to a range of key in-vehicle functions, including point-of-load applications in 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 considerable performance advantages. It’s available in 12 fixed, output-voltage variants with a ±1% voltage-output accuracy, which is maintained across its entire -40° to 125° C operational temperature range.
Its 1.7 to 5.5V wide input-voltage range gives it the versatility to address numerous automotive application requirements, while its 60µA quiescent current mitigates standby power losses.
The AP7347DQ has an enable pin; a built-in active discharge function ensures that the system starts up in a known state if the device has been disabled. Overtemperature and short-circuit protection are integrated, incorporating a 180mA foldback current limit should a short-circuit occur.
