RTQ2533E - Richtek

RTQ2533E Low-Dropout Linear Regulator

The RTQ2533E is a high-current (3A), low-noise (6.8VRMS), high accuracy (1% over line, load, and temperature), low-dropout linear regulator (LDO) capable of sourcing 3A with an extremely low dropout (maximum 180mV). The device supports a single input supply voltage as low to 1.1V, which makes it easy to use. The low-noise, high PSRR, and high output current.
