TPS54120
Description
The TPS54120 combines the high-efficiency of a step-down switching (dc-dc) converter with a high power-supply rejection (PSR), low-noise, low-dropout regulator (LDO) to provide an ultra low-noise power supply that delivers quiet power rails to noisesensitive applications. With a wide input range of 4.5 V to 17 V, the TPS54120 is ideally suited for systems with 12-V power busses, and supports a 1-A continuous output current.
