TPS7A85 Low-Noise Low-Dropout Linear Regulator

Texas Instruments TPS7A85 Low-Noise Low-Dropout Linear Regulator (LDO) is capable of sourcing 4A with only 240mV of maximum dropout. The device output voltage is pin-programmable from 0.8V to 3.95V and adjustable from 0.8V to 5.0V using an external resistor divider. The combination of low-noise (4.4µVRMS), high-PSRR, and high output current capability makes the TPS7A85 ideal for powering noise-sensitive components. These are commonly found in high-speed communications, video, medical, or test and measurement applications. The high performance of the TPS7A85 limits power-supply-generated phase noise and clock jitter. This makes these ideal for powering high-performance serialiser and deserialiser (SerDes), analogue-to-digital converters (ADCs), digital-to-analogue converters (DACs), and RF components.
