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 0.1V increments within a range of 1.2V ~ 3.6V. The series is also patible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series. The limiter's feedback circuit also operates as a protect for the output current limiter The CE function enables the output to be turned off, resulting in greatly reduced power consumption.The WL9003 consumes less than 1μA in shutdown mode and has fast turn-on time less than 50s. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio.
