LC1761 - LEADCHIP

LC1761 Dual 300mA High PSRR Linear Regulator

LC1761 dual, low-noise, low-dropout regulator delivers at least 300mA of continuous output current. The output voltage for each regulator is set independently by trimming. Output voltages are selectable in 100mV steps within a range of 1.2V to 3.5V.Typical output noise is 47uVrms, and PSRR is 73dB at 100Hz. The LC1761 includes two independent logic-controlle.
