When powering certain noise sensitive applications, an LDO may be required to filter or clean up the input signal. The ISL80101 family of parts will provide 1A (ISL80101), 2A (ISL80102) or 3A (ISL80103) of current from an input voltage up to 6V. The PSRR number for the part is ~75dB @ 100 Hz and is very consistent across the load current range. These parts typically will power an ADC or amplifier where the input voltage may be generated from 24V to 3.6V via a switching regulator and then down to the required 3.3V through an LDO. The transient response for this part is very good, at 2µs for a 0A to 3A load step. This is very important in these applications where motors or other loads may require the power to react very quickly.
