FeaTures DescripTion
36V
IN
, 5A µModule
Regulator with 5-Output
Configurable LDO Array
The LT M
®
8001 is a 36V
IN
, 5A step-down μModule
®
regu-
lator with a 5-output configurable LDO array. Operating
over an input voltage range of 6
V to 36V, the LTM8001
buck regulator supports an output voltage range of 1.2V
to 24V. Following the buck regulator is an array of five
1.1A linear regulators whose outputs may be connected
in parallel to accommodate a wide variety of load combi
-
nations. Three of these LDOs are tied to the output of the
buck regulator, while the other two are tied together to
an undedicated input.
The low profile package (3.42mm) enables utilization of
unused space on the bottom of PC boards for high density
point of load regulation. The LTM8001 is packaged in a
thermally enhanced, compact (15mm × 15mm) and low
profile (3.42mm) overmolded ball grid array (BGA) pack
-
age suitable for automated assembly by standard surface
mount equipment
.
The LTM8001 is available with SnPb
(BGA) or RoHS compliant terminal finish.
