2 A low-noise, high-accuracy ultra-low-dropout LDO, 1.1 V input — 12-pin VQFN-HR
The TPS7A5201RPSR is a 2 A linear regulator from Texas Instruments designed for low-voltage rails that need low noise and tight accuracy, such as FPGA, ASIC and DSP cores, high-speed SerDes and data converter supplies. With the BIAS pin it accepts inputs from 1.1 V, holds 0.5% accuracy over line, load and temperature, and drops out only 65 mV at 2 A. Output is adjustable from 0.8 V to 5.2 V and output noise is 4.4 µVRMS.

FAQ
Is the TPS7A5201RPSR in production?
Yes. Texas Instruments lists the TPS7A52 as Active. Distributor stock has been limited, so confirm availability and lead time before freezing a build plan.
Is the automotive version a drop-in alternate?
TI also offers TPS7A5201-Q1 parts, but in a different package. Check the footprint and qualification your design requires before substituting.
