LD49150XX08 1.5 VERY LOW DROP VOLTAGE REGULATOR

The LD49150xx is a high-bandwidth, low-dropout, 1.5 A 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 1.4 V to 5.5 V and the bias supply requires between 3 V and 6 V for proper operation. The LD49150xx offers fixed output voltages from 0.8 V to 1.8 V and adjustable output voltages down to 0.8 V. The LD49150xx requires a minimum output capacitance for stability, and work optimally with small ceramic capacitors
