Diodes introduces a series of low dropout regulators to provide industry-leading quiescent current

     Diodes launched a new LDO series to expand its power management product portfolio. The AP7387 device can be used in wireless vacuum cleaners, smoke detectors, electric tools and other household appliances AP7387 series is packaged with SOT23, SOT25, SOT89 and U-DFN2020-6

     The input voltage range of these devices is 5V to 60V, so they can be flexibly connected to 5V, 9V, 12V, 24V and 48V rails. The quiescent current of LDO is only 2 µ A, which is far lower than that of other competitive devices. Therefore, very little battery power is consumed, which allows the built-in LDO equipment to extend the operation time.

     Although the AP7387 series only consumes 2 µ A current, it has a 70dB high power supply voltage rejection ratio (PSRR) at 1kHz, and fast line/load transient response, which helps to adjust the transient changes of input voltage and load current. These two properties make it very suitable for noise sensitive product applications.

     The rated output current of AP7387 device is 150mA, and the fixed output voltage versions of 3.0V, 3.3V, 3.6V and 5V are introduced, with an output tolerance of ± 2%. The device incorporates functions such as current limitation, short circuit and overheating protection to improve the stability of the device and system, and also meets the requirements of electrostatic discharge (ESD) of 4kV manikin (HBM).
