Ultra low dropout regulators from Diodes
1 min read
Diodes' new series of fixed and adjustable output linear regulators is designed to reduce power consumption and increase regulated voltage output stability.
The AP7362 and AP7363 have a dropout voltage of 220mV at 1.5A and are targeted at a variety of energy sensitive microprocessor applications in monitor, printer and set top box products. According to Diodes, the accuracy of both regulators' adjustable voltage output is maintained irrespective of circuit conditions, varying typically +/- 1.5% at 25ºC and +/-3% over the full line voltage, load and ambient temperature ranges.
The devices feature precision current limit and thermal shutdown functions to ensure they remain safe from damage during fault conditions. Quiscent current is rated at 25nA in shutdown mode, which Diodes says boost overall efficiency.
In addition, the regulator have an output voltage range of 0.6 to 5V. Fixed output voltage options of 1, 1.2, 1.5, 1.8, 2.5 and 3.3V are also available. The AP7362 and AP7363 are provided in DFN2030-8 and SO-8 exposed pad packages.
