Description

The DIODES AP7583Q/AQ series are 300mA LDO for automotive battery-powered applications. The AP7583Q features 2.5µA quiescent current at light loads. Therefore, the AP7583Q/AQ are suitable solution to supply always power-on components, such as microcontroller (MCUs) and controller area network (CAN) transceivers.

The AP7583Q/AQ have features of wide input-voltage range, high accuracy, low-dropout voltage, current limit and ultra-low quiescent current, which make it ideal for automotive applications. The AP7583AQ has power-good indicator.

The IC consists of a voltage reference, an error amplifier, a resistor network for setting output voltage, a current-limit circuit for current protection, and a chip-enable circuit.

The AP7583Q/AQ both have 3.3V and 5V fixed output-voltage version, and adjustable version.

The AP7583Q is available in space-saving W-DFN2020-6 (SWP) (Type A1) package, and AP7583AQ has good power dissipation packages of MSOP-8EP, W-DFN2020-6 (SWP) (Type A1), and TO252-4 (Type C).
