VOUT = 5V + COUT 1µF Figure 2. ADP7105 with Adjustable Output Voltage, 5 V APPLICATIONS Regulation of noise sensitive applications: ADC and DAC circuits, precision amplifiers, high frequency oscillators, clocks, and PLLs munications and infrastructure Medical and healthcare Industrial and instrumentation GENERAL DESCRIPTION The ADP7105 is a CMOS, low dropout (LDO)linear regulator that operates from 3.3 V to 20 V and provides up to 500 m A of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed-signal circuits operating from 1.22 V to 19 V rails. Using an advanced proprietary architecture, the ADP7105 provides high power supply rejection and low noise, and achieves excellent line and load transient response with only a small 1 µF ceramic output...
