    Blog Post: Design a pre-tracking regulator, part 1: for a positive-output LDO
    Published. February 18, 2019

    By Arief Hernadi and Frank DeStasi The efficiency of a low-dropout regulator (LDO) depends on its input voltage and output voltage, since the input current drawn from the power supply will be equal to the current required at the output of the LDO. Therefore, a higher input and output voltage difference in the LDO translates to a lower efficiency value, and vice versa. An LDO with low efficiency translates into power loss and causes heating inside the device. Sometimes, you are going to need an LDO...

    UVM-ML- Managers’ Freedom of Choice
    Published. June 28, 2018

    Freedom of choice is a term we hear a lot, especially in the last 10 years. It is defined in wikipedia as “an individual's opportunity and autonomy to perform an action selected from at least two available options…”. Is having many choices always a good thing? Well, usually it is- who would not want to live in a world where s/he has options and can make choices? However, there are also downsides to having multiple options. In the TED lecture, The paradox of choice , Barry Schwartz discusses...
