ADPL42005 LDO Linear Regulators

Analog Devices Inc. ADPL42005 LDO Linear Regulators are designed for high-performance analog and mixed‐signal circuits operating from 19V to 1.22V rails. These regulators operate from 4V to 20V voltage and provide up to 500mA of output current. The ADPL42005 regulators utilize advanced proprietary architecture to provide high power supply rejection, low noise, and achieve excellent line and load transient response. These regulators are available in six fixed output voltage options and an adjustable version. This allows output voltages that range from 1.22V to VIN − VDO through an external feedback divider. The ADPL42005 LDO regulators feature an output noise voltage of 32µVrms that is independent of the output voltage. A digital power-good output allows power system monitors to check the health of the output voltage. A user-programmable precision undervoltage lockout function facilitates the sequencing of multiple power supplies.
