MIC49300
3A Low Voltage LDO Regulator with Dual
Input Voltages
General Description
The MIC49300 is a high-bandwidth, low-dropout, 3.0A
voltage regulator ideal for powering core voltages of low-
power microprocessors. The MIC49300 implements a dual
supply con?guration allowing for very low output
impedance and very fast transient response.
The MIC49300 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 o peration. The MIC49300 offers ?xed output
voltages from 0.9V to 1.8V and adjustable output voltages
down to 0.9V.
The MIC49300 requires a minimum of output capacitance
for stability, working optimally with small ceramic
capacitors.
The MIC49300 is available in a 5-pin S-Pak. It operates
over a junction temperature range of – 40°C to +125°C.
