MIC49150YMM

MICREL SEMICONDUCTOR  MIC49150YMM  电压稳压器, LDO, 可调, 1.4V至6.5V输入, 280mV压差, 900mV至5V/1.5A输出, SOP-8

The is a high-bandwidth low-dropout Voltage Regulator ideal for powering core voltages of low-power microprocessors. The MIC49150 implements a dual supply configuration allowing for very low output impedance and very fast transient response. The MIC49150 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 1.4 to 6.5V and the bias supply requires between 3 and 6.5V for proper operation. The MIC49150 offers fixed output voltages from 0.9 to 1.8V and adjustable output voltages down to 0.9V. The MIC49150 requires a minimum of output capacitance for stability, working optimally with small ceramic capacitors.
