Specializing in powering low power microprocessor cores, MIC49300 low-dropout regulator (LDO) features 3.0A output current and 0.9V output voltage, with the dual supply LDO said to respond instantly to any abrupt change in load current. The main supply requires only 400 mV headroom, or dropout voltage, under worst case conditions to maintain proper regulation, while the second, higher supply provides bias voltage to the control circuit. The IC supports input voltages as low as 1.4V, allowing for high efficiency conversion from low voltage, high current power rails. The upper end of the device's input range is 6.5V. Other MIC49300 features include thermal shutdown, current limit protection, and the ability to use ceramic output capacitors. The device also features a gain bandwidth of up to 10 MHz, enabling ultra-fast transient response. In a five-lead S-Pak package, price is $2.60 each/1,000.
