Wide input voltage LDO for 12V and 24V automotive systems
Diodes has introduced a low dropout (LDO) linear voltage regulator with a wide input range for 12V and 24V automotive systems.
The AP7387Q delivers a maximum output current of 150mA with a wide input voltage of 5V to 60V, and a dropout voltage of 700mV (typical) at a 100mA output current. It provides engineering teams with a simple-to-implement point-of-load (PoL) solution for automotive audio, navigation, tail lights, transmission control units, and battery management systems.
The quiescent current is 2µA for systems that are permanently connected to a battery, helping to extend runtime. The LDO has a power supply rejection ratio (PSRR) of 70dB at 1kHz and a fast line/load transient response against rapid changes to the input voltage or load current.
The LDO is AEC-Q100 Grade 1 qualified, manufactured in IATF 16949 certified facilities and supports PPAP documentation. In 1,000 piece quantities, the AP7387Q-XXY-13 (SOT89) is available at $0.67 and the AP7387Q-XXFDCW-7 (U-DFN2020-6 (SWP) (Type UXC)) is available at $0.80.
