High Performance 1A LDO
ISL80101
The ISL80101 ia a low-voltage, high-current, single
output LDO specified for 1A output current. This part
operates from input voltages of 2.2V to 6V and is capable
of providing output voltages of 0.8V to 5V on the
adjustable V
available in 0.8V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V.
Other custom voltage options available upon request.
For applications that demand in-rush current less than
current limit or a longer delay for a valid V
external capacitor on the soft-start pin provides
adjustment. A supply independent ENABLE signal allows
the part to be placed into a low quiescent current
shutdown mode. Sub-micron CMOS process is utilized for
this product family to deliver best in class analog
performance and overall value.
This CMOS LDO will consume significantly lower
quiescent current as a function of load over bipolar LDOs,
which translates into higher efficiency and the ability to
consider packages with smaller footprints. Quiescent
current is modestly compromised to enable leading class
fast load transient response and hence total AC
regulation band for an LDO in this category.
