Texas Instruments TPS54122QRHLRQ1

The TPS54122-Q1 combines the 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 ultralow-noise power supply that delivers QuietSupply rails to noise-sensitive 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 output voltage can be set from 0.8 V to 3.6 V and the dc-dc can be adjusted from 0.83 V to 5.0 V using external resistors. The TPS54122-Q1 can be used in a wide range of low-noise applications because the dc-dc converter and LDO are completely configurable. In addition, the TPS54122-Q1 includes features such as soft-start, switching frequency synchronization, and a power-good signal.

The TPS54122-Q1 can also be configured as a dual-supply rail device, supplying a total of 3 A.

The TPS54122-Q1 is available in a space-saving, 3.5-mm × 5.5-mm VQFN package, and is specified to operate over a –40°C to 125°C ambient temperature range. The TPS54122-Q1 is suited for automotive applications because the device is qualified for AEC-Q100 grade 1.
