General Description

The MIC47150 is a high-bandwidth, low-dropout, 1.5A volt-

age regulator ideal for powering core voltages of low-

power microprocessors. The MIC47150 implements a dual

supply

impedance and very fast transient response.

The MIC47150 requires a bias input supply between 3V

and 6.5V for proper operation. The main input supply rail

operates from 1.4V to 6.5V that allows for adjustable

output voltages down to 0.9V.

The MIC47150 requires a minimum of 1µF output

capacitance for stability, and optimal operation is achieved

with small ceramic capacitors.

The MIC47150 is available in a 5-pin power D-Pak

package (TO-252) with an operating temperature range of

–40°C to +125°C.
