RTQ2539C - Richtek

RTQ2539C Ultra-Low Dropout Linear Regulator

The RTQ2539C 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 extremely low dropout (max. 180mV for RTQ2539CGQV and max. 130mV for RTQ2539CGQWF). The device supports single input supply voltage as low to 1.1V, which makes it easy to use. The low-n.
