Diodes Incorporated Introduces Fast Transient Response LDO for Low Power and Portable Applications.

* Target End-Products Including Mobile Phones, Digital Media Players, Bluetooth Headsets and Handheld GPS 

DALLAS -- Diodes Incorporated (Nasdaq:DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, today announced the launch of a new 300-mA fast transient response LDO, which combines low quiescent current and adjustable regulation down to 1.0V making it optimized for portable and low-power applications such as mobile phones, digital media players, Bluetooth headsets and handheld GPS.

Designed for simple integration into a wide variety of low-power circuits, the new LDO can deliver up to 300mA from a 2V to 6V input range and provides the faster transient response required increasingly by today's high speed logic, DSPs, and micro-controllers, while still requiring only a standard 1uF ceramic output capacitor, reducing the size and cost of this external component. And it achieves this with a quiescent current half of what is typical for a device of this performance. The AP133 is ideal to power the latest fast-clock low-voltage core ICs currently used in many low power portable applications. With a low quiescent current of 40 microamperes (mA), the AP133 requires only a small amount of current to maintain regulation from 0mA load to full load, thereby significantly extending battery run-time; and the AP133 only sees an output voltage sag during fast load transients of less than one-third that of its closest competitors.

"The introduction of AP133 extends our traditional LDO product range and marks the first of several new high performance LDOs planned for introduction this year," remarked Mark King, Senior Vice President, Sales and Marketing of Diodes Incorporated. "Targeting performance oriented applications requiring the flexibility of adjustable output voltage down to an industry leading 1.0V effectively opens our LDO product line to the portable consumer electronic market."

Providing an adjustable output voltage from 5V down to 1.0V, approximately 20% lower than comparable devices, this LDO also features circuit-protection capabilities such as over-current protection, short-circuit protection, and thermal shutdown preventing system failures. With highly accurate output-voltage regulation, including +/- 2 percent accuracy, the AP133 helps to ensure accurate, reliable system operation from -40[deg]C to +85[deg]C ambient temperature range.

The adjustable LDO, AP133, is offered in the small SOT-25 package and in a 35% smaller package option, the micro 2mm x 2mm DFN2020-6 package, ideal for both industrial and portable applications.
