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 BIAS input current is reduced down to less than 2µA during shutdown. These regulators use small, 1µF ceramic input capacitors and 4.7µF ceramic output capacitors to deliver 1A output current. 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.
