ADP7118 with 5 V Output Adjusted to 6 V Adjustable output from 1.2 V to V V , output can be IN DO adjusted above initial set point Precision enable 2 mm 2 mm, 6-lead LFCSP, 8-Lead SOIC, 5-Lead TSOT AEC-Q100 qualified for automotive applications APPLICATIONS Regulation to noise sensitive applications ADC and DAC circuits, precision amplifiers, power for VCO VTUNE control Communications and infrastructure Medical and healthcare Industrial and instrumentation Supported by ADIsimPower tool GENERAL DESCRIPTION The ADP7118 is a CMOS, low dropout (LDO) linear regulator Additional voltages available by special order are 1.5 V, 1.85 V, that operates from 2.7 V to 20 V and provides up to 200 mA of 2.0 V, 2.2 V, 2.75 V, 2.8 V, 2.85 V, 3.8 V, 4.2 V, and 4.6 V. output current. This high input voltage LDO is ideal for the Each fixed output voltage can be adjusted above the initial set regulation of high performance analog and mixed-signal circuits point with an external feedback divider. This allows the ADP7118 operating from 19 V down to 1.2 V rails. Using an advanced to provide an output voltage from 1.2 V to V V with high IN DO proprietary architecture, the device provides high power supply PSRR and low noise. rejection, low noise, and achieves excellent line and load transient User programmable soft start with an external capacitor is response with a small 2.2 F ceramic output capacitor. The available in the LFCSP and SOIC packages. ADP7118 regulator output noise is 11 V rms independent of the output voltage for the fixed options of 5 V or less. The ADP7118 is available in a 6-lead, 2 mm 2 mm LFCSP making it not only a very compact solution, but it also provides The ADP7118 is available in 16 fixed output voltage options. excellent thermal performance for applications requiring up to The following voltages are available from stock: 1.2 V 200 mA of output current in a small, low profile footprint. The (adjustable), 1.8 V, 2.5 V, 3.3 V, 4.5 V, and 5.0 V. ADP7118 is also available in a 5-lead TSOT and an 8-lead SOIC. Rev.
