They are fabricated using Torex’s CMOS process. The series features a voltage reference, an error amplifier, a current limiter, and a phase compensation circuit plus a driver transistor. With a low ON resistance driver transistor built into, batteries can be used until input-output voltage differential is minimal and can accordingly be used for a longer time. The series is also compatible with low ESR ceramic capacitors www.DataSheet4U.com which give added output stability. The output voltage of the LDO is selectable in 50mV increments within the range of 0.8V to 5.0V. The current limiter's foldback circuit also operates as the output current limiter and the output pin protection. The IC's internal regulator circuit can be placed in stand-by mode via the CE function. In the stand-by mode, power consumption is greatly reduced. ■FEATURES : More than 700mA (800mA limit, TYP.)
