The LX8816 is a dual channel
positive-voltage linear regulator. This
dual regulator has one fixed output
coupled with an adjustable output.
Each channel features low-dropout
and high accuracy.
The LX8816 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
and directing quiescent current to the
load.
The LX8816 features on-chip
trimming of the internal voltage
enabling precise output voltages,
typically
鹵1%
of it鈥檚 specified value,
while the BiPolar output transistor has a
low dropout voltage even at full output
current (V
DO
< 1.2V typ. @ 1A).
Thermal and Short Circuit Current
Protection are integrated on-chip and
operate independently for each regulator
output.
The LX8816 regulator is stable with a
low-value output capacitor, typically
2.2碌F on the outputs, allowing designers
flexibility in external component
selection.
Microsemi鈥檚 S-PAK package enables
maximum power dissipation and ease of
assembly
using
surface
mount
technology.
