RTQ2521A - Richtek

RTQ2521A Ultra Low Dropout Linear Regulator

The RTQ2521A is a high-current (1.5A), low-noise (7μVRMS), high accuracy (1% over line, load, and temperature), low-dropout linear regulator (LDO) capable of sourcing 1.5A with extremely low dropout (max. 110mV). The device supports single input supply voltage as low to 1.1V that makes it easy to use. The low noise, high PSRR and high output current capabili.
