ADP7104ACPZ-3.3-R7

ADP7104 is a CMOS, low dropout linear regulator. This high input voltage LDO is ideal for regulation of high performance analogue and mixed‐signal circuits operating from 19V to 1.22V rails. Using an advanced proprietary architecture, it provides high power supply rejection, low noise, and achieves excellent line and load transient response with just a small 1µF ceramic output capacitor. A digital power-good output allows power system monitors to check the health of the output voltage. A user programmable precision under voltage lockout function facilitates sequencing of multiple power supplies. It is widely used in application such as regulation to noise sensitive applications: ADC, DAC circuits, precision amplifiers, high frequency oscillators, clocks, and PLLs, communications and infrastructure, medical and healthcare, industrial and instrumentation.
