High Performance 2A and 3A LDOs

ISL80102, ISL80103

ISL80102, ISL80103

The ISL80102 and ISL80103 are low voltage,
high-current, single output LDOs specified for 2A and 3A
output current, respectively. These parts operate from
input voltages of 2.2V to 6V and are capable of providing
output voltages of 0.8V to 5V on the adjustable V

OUT

versions. Fixed output voltage options available in 0.8V,

1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V. Other custom
voltage options availabl e upon request.

For applications that demand in-rush current less than
current limit, an external capacitor on the in-rush set pin
provides adjustment. The ENABLE feature 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 the best in class analog
performance and overall value.

These CMOS LDOs 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 a leading
class fast load transient response, and hence a lower
total AC regulation band for an LDO in this category .
