Description

General part information

TPS7A47 Series

The TPS7A47 is a family of positive voltage (+36 V), ultralow-noise (4 µVRMS) low-dropout linear regulators (LDO) capable of sourcing a 1-A load.

The TPS7A4700 output voltages are user-programmable (up to 20.5 V) using a printed circuit board (PCB) layout without the need of external resistors or feed-forward capacitors, thus reducing overall component count.

The TPS7A4701 output voltage can be configured with a user-programmable PCB layout (up to 20.5 V), or adjustable (up to 34 V) with external feedback resistors.
