The series achieves high ripple rejection and low dropout and consists of a standard voltage source, an error correcti on, current limiter and a phase compensation circuit plus a driver transistor. Output voltage is selectable in 100mV increments within a range of 1.5V~5.0V. The series is also compatible 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 current limiter's feedback circuit also operates as a short protect for the output current limiter and the output pin The EN function enables the output to be turned off, resulting in greatly reduced power consumption. The A6304A are available in SOT-25 and SC70-5 packages.
