High Performance 2A and 3A Linear Regulators
ISL80102, ISL80103
The ISL80102 and ISL80103 are low voltage, high-current, single
output LDOs specified for 2A and 3A output current, respectively.
These LDOs 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
versions. Fixed output voltage options are
OUT
available in 1.8V, 2.5V, 3.3V and 5V. Other custom voltage
options available upon request.
For applications that demand in-rush current less than the
current limit, an external capacitor on the soft-start pin provides
adjustment. The ENABLE feature allows the part to be placed into
a low quiescent current shutdown mode. A sub-micron BiCMOS
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.
