The LD49150xx is a high-bandwidth, low-dropout, 1.5A voltage regulator, ideal for powering core voltages of low-power microprocessors. The LD49150xx implements a dual supply configuration allowing for very low output impedance and very fast transient response. The LD49150xx requires a bias input supply and a main input supply, allowing for ultra-low input voltages on the main supply rail. The input supply operates from 1.4V to 5.5V and the bias supply requires between 3V and 6V for proper operation. The LD49150xx offers fixed output voltages from 0.8V to 1.8V and adjustable output voltages down to 0.8V. The LD49150xx requires a minimum output capacitance for stability, and work optimally.
