1A Low Dropout Adjustable and Fixed Mode Regulator EM1109 General Description The EM1109 performs ultra- low drop voltage, high power supply rejection ratio (PSRR), fast response, low noise linear regulator, and designed to continuously deliver up to 1A output current. The EM1109 has wide adjustable output voltage range and high output accuracy to 1.5%. No by-pass capacitor is needed for this device and only 4.7uF ceramic capacitor is required for stability in any loading conditions. It reduces the amount of board space necessary for power applications. The other features include soft start, current limit protection, Power-On-Reset function, and over temperature protection. The EM1109 is available in DFN3X3-08L package.
