Description

General part information

CS5253B-8 Series

This new very low dropout linear regulator reduces total power dissipation in the application. To achieve very low dropout, the internal pass transistor is powered separately from the control circuitry. Furthermore, with the control and power inputs tied together, this device can be used in single supply configuration and still offer a better dropout voltage than conventional PNP-NPN based LDO regulators. In this mode the dropout is deter-mined by the minimum control voltage.The CS5253B-8 is offered in a five-terminal D 2 PAK package, which allows for the implementation of a remote-sense pin permitting very accurate regulation of output voltage directly at the load, where it counts, rather than at the regulator. This remote sensing 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 1mV for an output voltage of 2.5V with a load step of 10mA to 3A.The CS5253B-8 has a very fast transient loop response.Internal protection circuitry provides for "bust-proof" operation, similar to three-terminal regulators. This circuitry, which includes over-current, short circuit, and over-temperature protection will self protect the regulator under all fault conditions.The CS5253B-8 is ideal for generating a 2.5V 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-8 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.
