ADM7172ACPZ-1.8-R7

ADM7172 is a CMOS, low dropout linear regulator (LDO). This high output current LDO is ideal for regulation of high performance analog and mixed-signal circuits operating from 6V down to 1.2V rails. Using an advanced proprietary architecture, the device provides high power supply rejection and low noise, and achieves excellent line and load transient response with just a small 4.7µF ceramic output capacitor. Inrush current can be controlled by adjusting the start-up time via the soft start pin. The typical start-up time with a 1nF soft start capacitor is 1.0ms. Application includes regulation to noise sensitive applications: ADC and DAC circuits, precision amplifiers, PLLs/VCOs, and clocking ICs, communications and infrastructure, medical and healthcare, industrial and instrumentation.
