CS52510-1
10A LDO 5-Pin Adjustable Linear Regulator
Description
This new very low dropout regula-
tor is designed to power the next
generation of advanced micropro-
cessor. 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
TO-220 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 variations
due to load changes and resistive
voltage drops. Typical load regula-
tion measured at the sense pin is
1mV for an output voltage of 2.5V
with a load step of 10mA to 10A.
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, supply
sequencing and overtemperature
protection, will self protect the reg-
ulator under all fault conditions.
The CS52510-1 is ideal for generat-
ing a secondary 2 - 2.5V low voltage
supply on a motherboard where
both 5V and 3.3V are already
available.
