CS5258-1
8.0 A LDO 5-Pin Adjustable
Linear Regulator
This new very low dropout regulator is designed to power the next
generation of advanced microprocessors. 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 determined by the
minimum control voltage.
It is supplied in a five–terminal TO–220 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 1.0 mV for
an output voltage of 2.5 V with a load step of 10 mA to 8.0 A.
The very fast transient loop response easily meets the needs of the
latest microprocessors. In addition, a small capacitor on the Adjust pin
will further improve the transient capabilities.
Internal protection circuitry provides for “bust–proof” operation,
similar to three–terminal regulators. This circuitry, which includes
overcurrent, short circuit, supply sequencing and overtemperature
protection, will self protect the regulator under all fault conditions.
The CS5258–1 is ideal for generating a secondary 2.0–2.5 V low
voltage supply on a motherboard where both 5.0 V and 3.3 V are
already available.
