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 conﬁguration 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 operation. The MIC49300 offers ﬁxed 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.

Datasheets and support documentation are available on

Micrel’s web site at:
