A6155 Datasheet | AiT Semiconductor

DESCRIPTION The A6155 is a dual output, low noise; low-dropout regulator delivers at least 150m A of continuous output current. The output voltage for each regulator is set independently by trimming. Voltages are selectable in 100m V steps within a range of 1.2V to 5.0V. Typical output noise is 27u VRMS, and PSRR is 65d B at 1KHz. The A6155 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned of independently. The A6155 includes high accuracy voltage reference, error amplifier, and current limit circuit and output driver module. The A6155 has excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system and A6155 uses trimming technique to guarantee output voltage accuracy within ±2%. The A6155 is available in SOT-26 package.
