Dynamic compensation ldo
Webtors are usually the only key elements of the LDO that are not contained in a monolithic LDO. There are a number of factors that affect the response of an LDO circuit to a load transient. These factors include the internal compensation of the LDO, the amount of … WebMar 20, 2013 · A dynamic zero frequency-compensation technique for 3 A NMOS low dropout-regulator (LDO) is presented. The dynamic zero is adapted to load current to get an adequate phase margin with a load current variation from 0 to 3 A. The proposed NMOS LDO has been implemented in a standard 0.35 μm CMOS process, and the die size is as …
