Performance features of the series includes low output noise, high ripple rejection ratio, low dropout and very fast turn-on times. The CXLD64208 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators internally. The CXLD64208’s current limiters' foldback circuit also operates as a short protect for the output current limiter. The output voltage for each regulator is set independently by laser trimming. Voltages are selectable in 0.05V steps within a range of 0.8V to 5.0V. The CXLD64208 series is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. The CXLD64208 series is available in the SOT-26W or USP-6B, USP-6C ‘chip-scale’ package.
