ADP7118is a CMOS, low dropout linear regulator that operates from a 2.7 V to 20 V supply with a maximum output current of 200 mA. This high input voltage LDO is suitable for regulating high-performance analog and mixed-signal circuits from 20 V to 1.2 V supplies. The device uses an advanced proprietary architecture that provides high power supply rejection, low noise, and excellent line and load transient response with only a small 2.2 μF ceramic output capacitor.
The ADP7118 is available in 16 fixed output voltage options. Each fixed output voltage can be adjusted above the initial set point by an external feedback divider. This allows the ADP7118 to provide 1.2 V to VOUT – VDOwith high PSRR and low noise.
The LFCSP and SOIC packages allow user-programmable soft-start with external capacitors.
ADP7118The regulator output noise is 11 μVrms, independent of fixed option output voltages of 5 V and below. Available in 6-lead, 2 mm × 2 mm LFCSP packages, the ADP7118 is not only very compact, but also has excellent thermal performance for low-profile, small applications requiring up to 200 mA output current. The ADP7118 is also available in 5-lead TSOT and 8-lead SOIC packages.
