TPS54122-Q1 Description
The TPS54122-Q1 bines the efficiency of a stepdown switching (dc-dc) converter with a high powersupply rejection (PSR), low-noise, low-dropout regulator (LDO) to provide an ultralow-noise power supply that delivers QuietSupply rails to noisesensitive applications. The TPS54122-Q1 is ideally suited for systems with 5-V power busses and can support 3-A continuous output current on both the dc-dc or LDO output. The LDO...
