MIC59150
Ultra High Speed 1.5A LDO
General Description
The MIC59150 is a high-bandwidth, low-dropout, 1.5A
linear voltage regulator ideal for powering core voltages of
low-power microprocessors. The MIC59150 implements a
dual supply con ? guration allowing for a very low output
impedance and a very fast transient response.
The MIC59150 requires a bias input supply and a main
input supply, allowing for ultra-low input voltages on the
main supply rail. The device operates from an input supply
of 1.0V to 3.8V and bias supply between 3V and 5.5V. The
MIC59150 offers adjustable output voltages down to 0.5V.
The MIC59150 requires a minimum output capacitance for
stability, working optimally with small ceramic capacitors.
The MIC59150 is available in an 8-pin EPAD SOIC
package and its junction temperature range is –40°C to
+125°C.
