The LX8815 is a dual channel
positive-voltage linear regulator. This
dual regulator has either one fixed
output coupled with an adjustable
output or two fixed outputs. Each
channel features low-dropout and high
accuracy.
The LX8815 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
LX8815
trimming of the internal
features
on-chip
voltage reference enabling precise output
voltages, typically
±
1% of it’s specified
value, while the BiPolar output transistor
has a low dropout voltage even at full
output current (V
DO
< 1.1V typ. @ 1A).
Thermal and Short Circuit Current
Protection are integrated on-chip and
operate independently for each regulator
output.
The LX8815 regulator is stable with a
low-value output capacitor, typically
3.3
μ
F tantalum or 4.7
μ
F ceramic on the
outputs, allowing designers flexibility in
external component selection.
Linfinity’s S-PAK power package
offers maximum power dissipation and
ease of assembly using surface mount
technology.
