[March 29, 2022, Plano, Texas] Diodes Corporation (NASDAQ: DIOD) has expanded its power management portfolio with the introduction of a new series of low dropout regulators (LDOs). The AP7387 device can be used in cordless vacuum cleaners, smoke detectors, power tools, and other home appliances.
These devices have an input voltage range of 5V to 60V, allowing for flexible connection to 5V, 9V, 12V, 24V, and 48V rails. The LDO's quiescent current is only 2µA, significantly lower than competing devices, thus consuming minimal battery power and extending the operating time of devices with built-in LDOs.
Although the AP7387 series consumes only 2µA of current, its high power supply voltage rejection ratio (PSRR) of 70dB at 1kHz, coupled with fast line/load transient response, helps regulate instantaneous changes in input voltage and load current. Both of these attributes make it highly suitable for noise-sensitive product applications.
The AP7387 device has a rated output current of 150mA and is available in fixed output voltage versions of 3.0V, 3.3V, 3.6V, and 5V with an output tolerance of ±2%. The device incorporates current limiting, short-circuit, and overheat protection to enhance device and system robustness, while also meeting 4kV human body model (HBM) electrostatic discharge (ESD) requirements.
The AP7387 series is available in SOT23, SOT25, SOT89 and U-DFN2020-6 packages.
