The AP7387 Series from Diodes Incorporated are LDO Voltage Regulators that operate from 5 to 60 V. These fixed voltage regulators have a dropout voltage of 700-1100 mV and an output current of up to 150 mA. They are available at 3 V, 3.3 V, 3.6 V, and 5 V fixed output voltages. These LDO voltage regulators offer a very fast line/load transient response against the rapid input voltage and load current changes. They consist of voltage reference, an error amplifier, a current-limit circuit for current protection, short-circuit protection, and thermal shutdown protection circuits. These AEC-Q100/11/200 qualified LDO regulators are available in a surface-mount package and are ideal for battery-powered equipment, smoke detectors and sensors, EV and HEV battery management systems, home appliances, and microcontroller applications.
