Diodes Incorporated has expanded its portfolio of power management products with the newAP7387 series低滴p-out (LDO) voltage regulators that features an input voltage range spanning from 5V to 60V, which gives them the flexibility to be connected to 5V, 9V, 12V, 24V, and 48V rails and can be used in applications such as cordless vacuum cleaners, smoke detectors, power tools, and various other household appliances. With a quiescent current of just 2µA, which is significantly below that of competing devices, these LDOs present a minimal draw on the battery resources. Also, these devices meet 4kV human body model (HBM) electrostatic discharge (ESD) requirements.
This series has a high-power supply rejection ratio (PSRR) of 70dB at 1kHz, plus a fast line/load transient response which helps mitigate sudden input voltage and load current changes. These devices are rated at 150mA output current and are available in 3.0V, 3.3V, 3.6V, and 5V fixed output voltage versions with ±2% output tolerance. Moreover, current limit, short-circuit, and thermal shutdown protection mechanisms have all been incorporated to improve device and system robustness.
