High Performance 1A Linear Regulator with
Programmable Current Limiting
ISL80101A
The ISL80101A is a low dropout voltage, single output LDO
with programmable current limiting. This LDO operates from
input voltages of 2.2V to 6V, and is capable of providing output
voltages of 0.8V to 5V. Other custom voltage options are
available upon request.
A submicron BiCMOS process is utilized for this product family
to deliver the best-in-class analog performance and overall
value. The programmable current limiting improves system
reliability of end applications. An external capacitor on the
soft-start pin provides an adjustable soft-starting ramp. The
ENABLE feature allows the part to be placed into a low
quiescent current shutdown mode.
This CMOS LDO will consume significantly lower quiescent
current as a function of load compared to bipolar LDOs, which
translates into higher efficiency and packages with smaller
footprints. Quiescent current is modestly compromised to
achieve a very fast load transient response.
Table 1 shows the differences between the ISL80101A and
others in its family:
