GENERAL DESCRIPTION
o 1.425V to 3.6V Input Voltage Range FEATURES
o Output Voltage Programmable from 0.5V to VIN o Guaranteed Maximum 225mV Dropout at 1A Output Current o ±2% Output Accuracy Over Load, Line, and Temperature o Stable with Ceramic Capacitors o Fast Transient Response o 60µA Operating Bias Supply Current (MAX15028) o 1.2µA Shutdown Bias Supply Current (MAX15028) o Short-Circuit and Thermal Protection o -40°C to +125°C Operating Temperature Range o Soft-Start Limits Inrush Current o Thermally Enhanced 3mm x 3mm TDFN Package MAX15027/MAX15028 The MAX15027/MAX15028 low-dropout linear regulators operate from input voltages as low as 1.425V and deliver up to 1A of continuous output current with a typical dropout voltage of only 75mV. 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. High bandwidth provides excellent transient response and limits the output voltage deviation to 15mV for a 500mA load step, with only a 4.7µF ceramic output capacitor, and the voltage deviations can be reduced further by increasing the output capacitor.
