MIC59300
Ultra High Speed 3A LDO
General Description
The MIC59300 is a high-bandwidth, low-dropout, 3A linear
voltage regulator ideal for powering core voltages of low-
power microprocessors. The MIC59300 implements a dual
supply con ? guration allowing for a very low output
impedance and a very fast transient response.
The MIC59300 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
MIC59300 offers ? xed output voltages and adjustable
output voltages down to 0.5V.
The MIC59300 requires a minimum output capacitance for
stability, working optimally with small ceramic capacitors.
The MIC59300 is available in a 5-pin TO-263 and an 8-pin
EPAD SOIC package and its junction temperature range is
–40°C to +125°C.
