... The GM66500 series offers extremely low dropout (typically 400mV at 5.0A) and low ground current (typically 70mA at 5.0A). The GM66500 series is ideal for PC add-in cards that need to convert from standard 3.0V to 2.5V and 2.5V to 1.8V, down to new, lower core voltages. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the GM66500 series to provide 2 ...
