The ADPL42002 is a CMOS, low dropout (LDO) linear regulator that operates from 2.7V to 20V and provides up to 200mA of output current. This high input voltage LDO is ideal for the regulation of high-performance analog and mixed-signal circuits operating from 19V down to 1.2V rails. Using an advanced proprietary architecture, the device provides high power supply rejection, low noise, and achieves excellent line and load transient response with a small 2.2μF ceramic output capacitor. The ADPL42002 regulator output noise is 20μVRMS independent of the output voltage for the fixed options of 5V or less.
The ADPL42002 is available in four fixed output voltage options. The following voltages are available from stock: 1.2V (adjustable), 1.8V, 2.5V, 3.3V, and 5.0V.
Each fixed output voltage can be adjusted above the initial set point with an external feedback divider. This allows the ADPL42002 to provide an output voltage from 1.2V to VIN − VDO with high PSRR and low noise.
User programmable soft start with an external capacitor is available.
The ADPL42002 is available in a 6-lead, 2mm x 2mm LFCSP, making it not only a very compact solution, but it also provides excellent thermal performance for applications requiring up to 200mA of output current in a small, low-profile footprint. The ADPL42002 is also available in an 8-lead SOIC.
