The AP7387Q is a low dropout (LDO) linear voltage regulator that provides engineering teams with a simple-to-implement point-of-load (PoL) solution for automotive audio, navigation, taillights, transmission control units, and battery management systems.
Developed and sold by Diodes Inc, the AP7387Q has an output current of 150mA, a wide input voltage of 5V to 60V, and a dropout voltage of 700mV (typical) at a 100mA output current. Its quiescent current of just 2µA is essential in systems that are permanently connected to a battery, helping to extend runtime. With a high-power supply rejection ratio (PSRR) of 70dB at 1kHz, the device is optimized for noise-sensitive functions. The LDO also exhibits a fast line/load transient response against rapid changes to the input voltage or load current.
Thanks to its wide input voltage, the AP7387Q 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 LDO are AEC-Q100 Grade 1 qualified, manufactured in IATF 16949 certified facilities, and support 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.
