Miniature LDO From Diodes Incorporated Features Low Noise, Small Footprint And Accuracy Advantages

Diodes Incorporated (Nasdaq:DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced the AP7340 low-dropout regulator. With a high PSRR of 75dB at 1kHz and a low-noise performance of 60µVrms over the 10Hz to 100kHz range, the AP7340 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 -40˚C to +85˚C. This low-power LDO offers a typical quiescent current of just 35µA, helping to reduce product power consumption. For further information, visit the Company’s website at www.diodes.com.
