More Information
Operating from a minimum input voltage of 1.65 V, the LP3991 LDO has been designed to provide fixed stable output voltages for load currents up to 300 mA. This device is suitable where accurate low voltages are required from low input voltage sources and is therefore suitable for post regulation of switched mode regulators. In such applications, significant improvements in performance and EMI can be realized, with little reduction in overall efficiency. The LP3991 provides fixed outputs as low as 1.2 V from a wide input range from 1.65 V to 4 V Using the enable (EN) pin, the device may be controlled to provide a shutdown state, in which negligible supply current is drawn.
