High Performance 1A LDO
ISL80101
The ISL80101 is a low voltage, high current, single output LDO
specified at 1A output current. This LDO operates from input
voltages of 2.2V to 6V. Fixed output voltage options are
available in 1.8V, 2.5V, 3.3V and 5.0V versions. Other custom
voltage options are available upon request. For the adjustable
output version of the ISL80101, please refer to the
ISL80101-ADJ datasheet.
A sub-micron BiCMOS process is utilized for this product family
to deliver the best in class analog performance and overall
value. This CMOS LDO consumes significantly lower quiescent
current as a function of load compared to bipolar LDOs, which
translates into higher efficiency and packages with smaller
footprints. State of the art internal compensation achieves a
very fast load transient response. 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. A Power-Good logic output
signals a fault condition.
Table 1 shows the differences between the ISL80101 and
others in its family:
