Diodes introduces the first Low Voltage Difference (LDO) linear regulator compliant with AEC-Q100 Grade 1. The AP7315Q and AP7343Q offer 150mA and 300mA, respectively, for any automotive application that requires precise voltage regulation under a variety of operating conditions, such as point-of-load power supply for advanced driver assistance systems (ADAS), RF communications, infotainment systems and cameras. Both regulators are available in SOT25 package.
Automakers are incorporating increasingly sophisticated levels of ADAS into their vehicles, including a variety of sensors and sensing circuits that require extremely stable power supplies. The AP7315Q and AP7343Q linear regulators are equipped with full Production Parts Approval Process (PPAP) capabilities and can be used in automotive applications where products are required to meet AEC-Q100 and Grade 1 (-40°C to +125°C) temperature ratings.
For demanding automotive applications, the AP7315Q and AP7343Q provide a practical alternative to switching regulators. In addition to current limiting and short circuit protection, both linear regulators have an enabling input that can be turned off when the linear regulator is not needed. They provide a low static current of only 35μA when used. Both linear regulators are available with (AP7315DQ/43DQ) or without (AP7315Q/43Q) output capacitor discharge, which is usually required to protect sensitive loads, such as CMOS image sensing components, when turned off.
