Low quiescent LDOs address 12V and 24V automotive systems
The AP7387Q is a low dropout (LDO) linear voltage regulator released by Diodes for automotive functions in vehicle design. It has a maximum output current of 150mA, with a wide input voltage of 5.0 to 60V and a dropout voltage of 700mV (typical) at a 100mA output current. According to Diodes, the LDO provides engineering teams with a simple-to-implement point of load (PoL) device for automotive audio, navigation, tail lights, transmission control units and battery management systems.
The AP7387Q’s quiescent current is just 2.0 microA which is lower than many competing devices, Diodes claimed. This is essential in systems that are permanently connected to a battery, to help in extending runtime. The device also has a high power supply rejection ratio (PSRR) of 70dB at 1kHz, making the AP7387Q which is optimised for noise-sensitive functions. The LDO also exhibits a fast line/load transient response against rapid changes to the input voltage or load current.
The AP7387Q has a wide input voltage and meets the load dump specifications of 12V internal combustion engine (ICE) vehicles such as cars, 24V ICEs such as buses, coaches, and trucks.
The AP7387Q LDOs from Diodes are AEC-Q100 Grade 1 -qualified, manufactured in IATF 16949 certified facilities and support PPAP documentation.
The AP7387Q-XXY-13 is available in an SOT89 package and the AP7387Q-XXFDCW-7 (U-DFN2020-6 (SWP) is available in a Type UXC package,
