With an ultra-low dropout voltage of only 220mV at 1.5A, the AP7362 and AP7363 fixed and adjustable output linear regulators from Diodes Incorporated help reduce power consumption and increase regulated voltage output stability. Their low dropout voltage performance combined with fast transient response to step changes in load make it suitable for a variety of energy sensitive microprocessor applications in monitor, printer and set top box products. The accuracy of both regulators' adjustable voltage output is tightly maintained irrespective of circuit conditions, varying typically just +/- 1.5% at 25°C and +/-3% over the full line voltage, load and ambient temperature ranges. In shutdown mode, quiescent current is also extremely low at 25nA, helping to boost overall circuit efficiency. For circuit protection, the integration of precision current limit and thermal shutdown functions ensure target devices remain safe from damage during fault conditions. Offering a wide adjustable output voltage range from 0.6V to 5.0V, the regulators enable a single part number to suit a broad range of applications by use of a simple two resistor voltage divider. Alternatively, fixed output voltage options of 1V, 1.2V, 1.5V, 1.8V, 2.5V and 3.3V removes the need for the divider and helps reduce PCB component count. For additional flexibility, the AP7362 and AP7363 are respectively provided with and without a logic high enable pin. Both devices are provided in DFN2030-8 and SO-8 exposed pad packages with the SOT223-3L package a further option for the fixed output AP7363 variants. The AP7362 is priced at $0.31 each in 10k quantities and the AP7363 at $0.29 each in 10k quantities.
