MAX15029/MAX15030
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 -40°C to +125°C. 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 2µA during the shutdown. These regulators use small, 1µF ceramic input
capacitors and 2.2µF 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 2.2µF ceramic output capacitor, and the
voltage deviations can be reduced further by increasing the...
