Miniature LDO from Diodes Incorporated Features Low Noise, Small Footprint and Accuracy Advantages

Plano, Texas – October 30th, 2013 – With a high PSRR of 75dB at 1kHz and a low-noise performance of 60µVrms over the 10Hz to 100kHz range, the AP7340 low-dropout regulator from Diodes Incorporated ensures a high-quality supply for analog circuits in noise-sensitive audio, video and RF applications.  With its 1.0mm x 1.0mm DFN1010-4 package, the AP7340 suits the highest density portable product designs.

This miniature, low-noise LDO produces a 150mA output current for a wide input voltage range, starting from as low as 1.7V and extending up to a maximum of 5.25V.  It comprises a voltage reference, error amplifier, current limit and an enable input for output on/off control.  Its integrated resistor network produces fixed output voltages in 0.1V steps between 1.2V and 3.3V.

The AP7340’s output voltage accuracy is higher than other industry solutions, with an accuracy of ±1.5% over the entire operating temperature range of -40ºC to +85ºC.  This low-power LDO offers a typical quiescent current of just 35µA, helping to reduce product power consumption.

The AP7340 is priced at $0.10USD each in single reel quantities of 5k.  Further information is available from www.diodes.com

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
