LDO linear voltage regulator provides output voltage rail in 100-mV increments

TEXAS INSTRUMENTS 1-A TPS7A4700 LDO linear regulator is high current, ultra-low noise, low dropout (LDO) voltage regulator that provides less than 4.17-uVrms output noise over the 10-Hz to 100-kHz bandwidth, eliminating the need for expensive and bulky filtering Device enables the setting of any output voltage rail in 100-mV increments with simple printed circuit board (pcb) layout changes. This eliminates the need for expensive, high accuracy, external feedback resistors, which saves board area and reduces component count when compared to existing solutions.
