Dual Channel 1A Low Dropout Regulator
Copyright
2003
Revision 1.0a, 4/29/2005
TM
DESCRI PTI O N
The LX8819 is a dual channel
positive-voltage linear regulator. This
dual regulator has one fixed output
coupled with an adjustable output.
Each channel features a low dropout
and a high accuracy.
The LX8819 provides designers
with a flexible power management
solution, minimal printed circuit board
area, and shorter design cycles.
Each channel can supply up to one
amp independently with a regulator
design optimized for system efficiency
by consuming minimal ground current
while directing quiescent current to
the load.
The
LX8819
features
on-chip
trimming
of
the
internal
voltage
reference
enabling
precise
output
Voltages (typically ±1% of its specified
value)
while
the
Bipolar
output
transistor has a low dropout voltage
even at full output current (VDO < 1.25V
typical @ 1A).
Thermal and Short Circuit Current
Protection are integrated on-chip and
operate independently for each of the
regulator output.
The LX8819 regulator is stable with
a low-value output capacitor (typically
2.2F on the outputs) allowing the
designers
flexibility
in
external
component selection.
Microsemi’s S-PAK and D-PAK
power
packages
enable
maximum
power dissipation and ease of assembly
using surface mount technology.
