Microchip Technology MIC49500-0.9WR-TR

Description
The MIC49500 is an ultra-high-bandwidth, low-dropout, 5.0A voltage regulator designed for powering core voltages of low-voltage microprocessors. It features a dual supply configuration for low output impedance and fast transient response. The MIC49500 requires a bias input supply and a main input supply, allowing for ultra-low input voltages on the main supply rail. It can regulate to an output voltage as low as 0.7V, making it suitable for low-voltage to low-voltage conversion. The MIC49500 requires minimal output capacitance for stability and works optimally with any type of capacitor, including small ceramic capacitors.
