Supply and Signal Line Filtering
08.25.2016 · Articles
There are many reasons for needing to filter power supply or signal lines. Power supply lines from a switching regulator may be too noisy for sensitive analog circuitry. Signal or power supply lines may pick up interference either from the rest of the system circuitry or from external devices. With signal lines the problem of filtering can particularly tricky because you want to remove any interference while preserving the integrity of the desired signal...

The device features a wide 5.5 V to 38 V input voltage range and includes independently enabled dual outputs: a 5 V 100 mA supply, and a 250 mA 3.3 V low-dropout (LDO) regulator, for a total of 350 mA available output current...
STMicroelectronics Reveals Ultra-Tiny Low-Dropout Regulator in Breakthrough Bumpless Chip-Scale Package
08.24.2016 · News
STMicroelectronics has introduced the LDBL20, a 200 mA Low-Dropout regulator in a minuscule 0.47 mm × 0.47 mm × 0.2 mm chip-scale package that is ideal for wearable and portable devices and for flexible electronics such as multifunction connected smart cards. The LDBL20’s bumpless STSTAMP package breaks through the minimum I/O-area and height limitation imposed by the diameter of traditional flip-chip solder bumps, enabling unprecedentedly small footprints and low mounted heights...
Locked-sync sine generator covers three decades with low distortion
08.23.2016 · Circuits
Analog applications, such as testing, calibration, and general system operation, often require a sine waveform of accurate amplitude and frequency, with low THD. Some applications demand that the generator of such waveforms have the ability to accurately synchronize the output with an external timing signal. Simple sine-wave generators can offer various degrees of this performance, but maintaining low THD with constant amplitude is a problem, particularly if the output and the synchronization signal must remain locked through an extended range of frequencies...
