LDOs from Diodes comply with AEC-Q100 grade 1

Suitable for any automotive application that requires tight voltage regulation across operating conditions, the AP7315Q and AP7343Q are the first low dropout (LDO) linear regulators to be produced by Diodes that comply to AEC-Q100-1.

The AP7315Q and AP7343Q deliver 150 and 300mA respectively and are suitable for point of load (PoL) power supplies in advanced driver assist systems (ADAS), RF communications, infotainment systems, and cameras.

They have full production part approval process (PPAP) capability and are for use in automotive applications that require product qualified to AEC-Q100 with a Grade 1 (-40 to +125°C) temperature rating.

The AP7315Q and AP7343Q provide practical alternatives to switching regulators in highly demanding automotive applications, says Diodes. As well as current limiting and short-circuit protection, the LDOs have an enable input that allows the linear regulators to be switched off when not required. While in use, the regulators have a low quiescent current of just 35 microA. Both devices are also available with (AP7315DQ and AP7343DQ) and without (AP7315Q and AP7343Q) an output capacitor discharge feature, which is often required to protect sensitive loads during shutdown, such as CMOS image sensors.

Both regulators are supplied in the SOT25 package.

Diodes manufactures application specific standard products within the broad discrete, logic, analogue and mixed-signal semiconductor markets. Diodes serves the consumer electronics, computing, communications, industrial, and automotive sectors. Diodes’ product portfolio includes diodes, rectifiers, transistors, MOSFETs, protection devices, function-specific arrays, single gate logic, amplifiers and comparators, Hall-effect and temperature sensors, power management devices, including LED drivers, AC/DC converters and controllers, DC/DC switching and linear voltage regulators and voltage references along with special function devices, such as USB power switches, load switches, voltage supervisors, and motor controllers. Diodes also has timing, connectivity, switching, and signal integrity products for high-speed signals.
