The MAX15029/MAX15030 low-dropout linear regulators operate from input voltages as low as 1.425V and deliver up to 500mA of continuous output current with a typical dropout voltage of only 40mV. The output voltage is adjustable from 0.5V to VIN and is 2% accurate over load and line variations, from -40C to +125C. The MAX15030 features a BIAS input of 3V to 5.5V from an always-on power supply. The BIAS input current is reduced down to less than 2A during the shutdown. These regulators use small, 1F ceramic input capacitors and 2.2F ceramic output capacitors to deliver 500mA output current. High bandwidth provides excellent transient response and limits the output voltage deviation to 10mV for a 100mA to 500mA load step, with only a 2.2F ceramic output capacitor, and the voltage deviations can be reduced further by increasing the output capacitor.
