This new very low dropout regula-
tor is designed to power the next
generation of advanced micropro-
cessors. To achieve very low
dropout, the internal pass transistor
is powered separately from the con-
trol 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 mini-
mum control voltage.
It is supplied in a five-terminal
D

PAK package, which allows for
the implementation of a remote-
sense pin permitting very accurate
regulation of output voltage direct-
ly at the load, where it counts,
rather than at the regulator. This
remote sensing feature virtually
eliminates output voltage varia-
tions due to load changes and resis-
tive 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 very fast transient loop
response easily meets the needs of
the latest microprocessors. In addi-
tion, a small capacitor on the Adjust
pin will further improve the tran-
sient capabilities.
Internal protection circuitry pro-
vides for òbust-proofó operation,
similar to three-terminal regulators.
This circuitry, which includes over-
current, short circuit, and over-tem-
perature protection will self protect
the regulator under all fault condi-
tions.
The CS5253-1 is ideal for generating
a secondary 2-2.5V low voltage
supply on a motherboard where
both 5V and 3.3V are already avail-
able.
