In July 2011, Analog Devices introduced the ADP5034 regulator/LDOn and the ADP5024 regulator/LDO, which have been designed to meet the shrinking board space and increasing performance requirements of processors and FPGAs.
Features and USP: The ADP5034 regulator/LDO is a highly integrated power management IC that combines two 3-MHz, high efficiency, 1.2-A step down regulators with two 300-mA LDO (low drop out) regulators in a small LFCSP (lead-frame chip-scale) package. The ADP5024 regulator/LDO is identical to the ADP5034, but features a single 300-mA LDO regulator. Both occupy a total board area of only 69 mm². The integrated LDOs feature a high 65-dB PSRR (power-supply rejection ratio) performance that ranges from 1 kHz to 10 kHz, lowering output noise to 80 Î¼V/rms for powering sensitive analogue circuitry.
