New Benchmark for LDOs XC6705/06: Ultra-Low Power 20V 200mA „Go" LDO
Traditionally, linear regulators have been classified as either being »Low Power«, meaning they consume low levels of quiescent current during operation, or »High-Speed«, meaning that the LDO responds very quickly to changes in load current (fast load transient response). High-speed LDOs also typically offer higher PSRR performance compared to low power solutions.
