The series achieves high ripple rejection and low dropout and consists of a standard voltage source, an error correction, current limiter and a phase pensation circuit plus a driver transistor. Output voltage is selectable in 0.05V increments within a range of 0.8V ~ 3.6V. The series is also patible with low ESR ceramic capacitors which give added output stability.It provides up to 500m A of output current in miniaturized packaging. The Features of low quiescent current as low as 0.3μA and almost zero disable current is ideal for powering the battery equipment to a longer service life. The other Features include current limit function, Integrated Short-Circuit Protection ,over temperature protection and Fast discharge...
