CS5253B-1
feature virtually eliminates output voltage variations due to load changes and resistive voltage drops. Typical load regulation measured at the sense pin is less than 1.0 m V for an output voltage of 2.5 V with a load step of 10 m A to 3.0 A. The CS5253B- 1 has a very fast transient loop response which can be adjusted using a small capacitor on the Adjust pin. Internal protection circuitry provides for “bust- proof” operation, similar to three- terminal regulators. This circuitry, which includes overcurrent, short circuit, and overtemperature protection will self protect the regulator under all fault conditions. The CS5253B- 1 is ideal for generating a 2.5 V supply to power graphics controllers used on VGA cards. Its remote sense and low value capacitance requirements make this a low cost, high performance solution. The CS5253B- 1 is optimized from the CS5253- 1 to allow a lower value of output capacitor to be used at the expense of a slower transient response.
