TPS7A4700RGWR Description
The TPS7A4700RGWR is a low-dropout linear regulator (LDO) with a positive voltage (+36 V) and ultralow noise (4 VRMS) capable of sourcing a 1-A load. The output voltages of the TPS7A4700RGWR are user-programmable (up to 20.5 V) using a printed circuit board (PCB) configuration that eliminates the need for external resistors or feed-forward capacitors, resulting in a lower overall component count.
Consider TI's TPS7A4700RGWR negative high-voltage, ultralow-noise linear regulators for applications that require both positive and negative low-noise rails.
