| Abstract: | Portable applications often need multiple voltages controlled by a power management IC to power up many functional blocks [1]. A switching pre-regulator is usually followed by a low dropout (LDO) regulator to provide a regulated power source for noise-sensitive blocks. The LDO regulator has to be stable for all load conditions and frequency compensation is usually needed to stabilize the regulation loop [2, 3]. The output voltage droop due to rapid and large load changes could be minimized with a fast regulation loop, such that functional blocks powered by the same LDO regulator would have low crosstalk noise. |
