Microchip Technology, Inc. Dual Supply, Low Voltage 3.0A LDO MIC49300

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. Additional Features Input voltage range: VIN: 1.4V to 6.5V VBIAS: 3.0V to 6.5V Stable with 1µF ceramic capacitor ±1% initial tolerance Maximum dropout voltage (VIN-VOUT) of 500mV over temperature Adjustable output voltage down to 0.9V Ultra-fast transient response (Up to 10MHz bandwidth) Excellent line and load regulation specifications Logic controlled shutdown option Thermal shutdown and current limit protection Power S-Pak package Junction temperature range: -40°C to +125°C
