Hot-selling and scarce MIC49300WR 3.0A Low Voltage LDO Regulator w/Dual Input Voltages SPAK-5 spot stock

Product Descriptions

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  confi 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 operation.  The MIC49300 offers fi 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.
