Diodes Corporation launches high-current, high-precision LDO for noise-sensitive power conversion product applications

 


【Lansheng Technology News】Diodes Corporation recently launched a rated 3A low dropout (LDO) voltage regulator that supports 4.4µVRMS operation (0.8V output voltage). The AP7179D provides a clean power supply optimized for driving noise-sensitive components such as high-performance SerDes, RF components, and data converters required in high-speed communications, test and measurement, medical, and video product applications. Hardware types such as remote radio units, outdoor backhaul units, mMIMO active antenna systems, ultrasonic scanners, radar systems and laboratory/field instruments can all use this product.


Diodes' AP7179D has ±1% output accuracy across line, load and temperature. The device's (maximum) 180mV dropout voltage at 3A load current supports a wide voltage conversion range. Its low-noise reference and error amplifier achieve the smallest noise floor. In addition, its 40dB power supply rejection ratio (PSRR) at 500kHz significantly reduces the coupling of input supply noise to the output.


This LDO has two output voltage selection modes: pin programmable mode from 0.8V to 3.95V, or adjustable mode from 0.8V to 5.5V using an external resistor divider. The resulting flexibility significantly reduces the number of auxiliary components required.


The device's low output noise mitigates phase noise and clock jitter generated by the power supply. This advantage and high current capability make this product compatible with high-performance processors such as FPGAs, ASICs, and DSPs.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
