AP7380 LDO regulator from Diodes is accurate for metering

Able to support a wide input voltage range with fixed output voltages, the AP7380 series of low dropout (LDO) regulators has been introduced by Diodes. The AP7380 operates from a 24V input voltage range and offers various fixed output voltages to address common system requirements, says Diodes. The AP7380 regulators can be used in USB power, portable equipment, consumer, instrumentation and metering applications.

The AP7380’s wide 3.5 to 24V input voltage range enables operation from standard 5.0, 9.0 and 12V system power rails, with sufficient overhead to cope with supply transients. Regulated output voltage variants at 3.0, 3.3, 4.15, 4.4 and 5.0V are offered, supporting common point-of-load (PoL) requirements. The device’s line/load regulation maintains a room temperature output accuracy of one per cent under all I/O voltage conditions, up to a maximum rated load current of 150mA.

The low dropout performance of the AP7380 is typified by a dropout voltage of just 250mV at an output voltage of 5.0V and load current of 50mA. The AP7380’s low quiescent current of 1.8A minimises standby power and extends the operating life of battery-powered equipment. The AP7380 also integrates a thermal shutdown function to protect equipment from over-temperature conditions.

The AP7380 series is offered by Diodes in SOT25 and SOT89 packages.
