A6155

AiT Semiconductor Inc. www.ait-ic.com A6155 LOW DROPOUT VOLTAGE REGULATOR 150mA DUAL OUTPUT CMOS LOW NOISE DESCRIPTION The A6155 is a dual output, low noise; low-dropout regulator delivers at least 150mA of continuous output current. The output voltage for each regulator is set independently by trimming. Voltages are selectable in 100mV steps within a range of 1.2V to 5.0V. Typical output noise is 27uVRMS, and PSRR is 65dB 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.
