LDO Controller drives digital ICs.
MIC5159 low dropout regulator controller drives low-voltage DSPs, microcontrollers, and logic ICs. Available in IttyBitty(TM) SOT-23-6 package, it requires very little headroom to provide well-regulated supply of 1.5, 1.8, or 2.5 V. Device's headroom, or dropout voltage, is limited only by RDS(ON) of external MOSFET. It has fast transient response, good regulation over variation of line, load,...
