Dropout regulator supports wide input voltage range

The AP7380 series of ultralow dropout regulators from Diodes is said to operate from a wide input voltage range and to offer various fixed output voltage options.

These features – combined with high accuracy and an ultralow quiescent current – are claimed to make the device suitable for use in various USB power, portable equipment, consumer, instrumentation and metering applications.

According to the company, the AP7380’s 3.5V to 24V input voltage range enables operation from standard 5V, 9V and 12V system power rails with sufficient overhead to cope with supply transients.

Regulated output voltage variants at 3.0V, 3.3V, 4.15V, 4.4V and 5.0V are offered, supporting common point-of-load requirements.

The device provides line/load regulation, maintaining a room temperature output accuracy of 1.0% under all I/O voltage conditions up to a maximum rated load current of 150mA.

The AP7380 is typified by a dropout voltage of 250mV, an output voltage of 5V and load current of 50mA, with low quiescent current of 1.8μA. The regulator also integrates a thermal shutdown function to protect equipment from over-temperature conditions.

The AP7380 series comes in SOT25 and SOT89 packages.
