MIC49150
1.5A Low Voltage LDO Regulator
w/Dual Input Voltages
General Description
The MIC49150 is a high-bandwidth, low-dropout, 1.5A volt-
age regulator ideal for powering core voltages of low-
power microprocessors. The MIC49150 implements a dual
supply con ? guration allowing for very low output
impedance and very fast transient response.
The MIC49150 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 1.4V to
6.5V and the bias supply requires between 3V and 6.5V
for proper operation. The MIC49150 offers ? xed output
voltages from 0.9V to 1.8V and adjustable output voltages
down to 0.9V.
The MIC49150 requires a minimum of output capacitance
for stability, working optimally with small ceramic
capacitors.
The MIC49150 is available in an 8-pin power MSOP pack-
age and a 5-pin S-Pak. Its operating temperature range is
–40°C to +125°C.
