What are typical applications for a low dropout (LDO) linear regulator? LDO linear regulators are usually employed in systems that require a low-noise power source instead of a switching regulator ...
Low dropout (LDO) regulators play a very important role in the power management of an integrated circuit. As a result, mindful designing and selection of LDO circuits become crucial. This article ...
In our previous post Low Power LDO Design Techniques for Really Small Profile Applications, Part 1, we reviewed LDO design tradeoffs using an NMOS pass transistor. This design approach is proven good ...
A regulator is a closed-loop feedback system. For the LDO to be stable, the phase margin must be positive. In other words, at unity gain crossover frequency of the gain curve, the phase of the system ...
Converter ICs include an integrated power MOSFET, whereas controller ICs employ external power MOSFETs. Both configurations are classified as regulators because they regulate the output voltage. A low ...
