The LD49300 is a high-bandwidth, low-dropout, 3.0 A voltage regulator, ideal for powering core voltages of low power microprocessors. The LD49300 implements a dual supply configuration, which guarantees a very low output impedance and a fast transient response. The LD49300 requires a bias input supply and a main input supply, allowing ultra-low input voltages on the main supply rail. The input supply operates from 1.4 V to 5.5 V and bias supply requires between 3 V and 6 V to work properly. The LD49300 offers fixed output voltages from 0.8 V to 1.8 V and adjustable output voltages from 0.8 V. The LD49300 requires a minimum output capacitance for stability, and works optimally with small ceramic capacitors.
