DESCRIPTION
Demonstration circuit 3071A features the
µModule
regulator, a complete, low input noise, ultrahigh
®
PSRR solution with an intermediate power bus and dual
output 0.5A LDO regulators, in a thermally enhanced, com-
pact 9mm × 6.25mm × 3.32mm BGA package. DC3071A
has a wide operating input range of 4V to 40V. Each of
the two outputs is an adjustable 3.3V/0.5A. The operating
output range is a wide 0V to 8V. DC3071A also allows for
the LDOs to be paralleled up to 1A rail load current.
The LTM8080 includes voltage tracking functionality,
external frequency synchronization, and low input noise
compliance with CISPR22 Class B. The built-in voltage

The µModule regulator targets applications that require
a complete switcher and LDO regulators solution with
configurable output channels, power good protection fea-
tures, and ultralow noise performance.
