Proposed schematic below using TPS73101DBVR . Hello, There are a few things happening here. First, the LM317 is easy to use as a current source because the internal reference is not connected directly to GND, it is floating. Most LDO's h...
to high spec lab equipment. Given a noisy input and a variable load, a voltage regulator will give a nice clean, stable output voltage. We’ve covered the basic operation and usage of the LM317manytimes. But even the most common of ...

There could be exceptions i guess, but one example is when adding a single transistor to add current feedback to a voltage regulator. The idea of course is to implement a known current limit when that is not built into the voltage regulator, especially when we want some adjustment too.A ...
For any current regulator, D is a function of the conversion ratio: Buck D = VO VIN (1) Boost D= VO - VIN VO (2) Buck-Boost D = VO VO + VIN (3) 7.3.2 Predictive Off-Time (PRO) Control PRO control is used by the LM3429 to control ILED. It is a combination of average ...
