MIC49200
2A Low Voltage LDO
with Dual Input Voltages
General Description
The MIC49200 is a high-bandwidth, low-dropout, 2A
voltage regulator ideal for powering core voltages of low-
power microprocessors. The MIC49200 implements a
dual supply con ? guration allowing for very low output
impedance and very fast transient response.
The MIC49200 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 MIC49200 offers ? xed output
voltages from 0.9V to 1.8V and adjustable output voltages
down to 0.9V.
The MIC49200 requires a minimum of output capacitance
for stability, working optimally with small ceramic
capacitors.
The MIC49200 is available in a 5-pin S-Pak. Its operating
temperature range is –40°C to +125°C.
