Analog Devices ADP5037 800mA Buck Regulators
Analog Devices ADP5037 800mA Buck Regulators combine two high-performance buck regulators and two low dropout (LDO) regulators in a small, 24-lead 4mm × 4mm LFCSP to meet demanding performance and board space requirements. The high switching frequency of this ADI device's buck regulators enables tiny multilayer external components and minimizes the board space. The two buck regulators operate out of phase to reduce the input capacitor requirement. The low quiescent current, low dropout voltage, and wide input voltage range of the ADP5037 LDOs extend the battery life of portable devices. The ADP5037 LDOs maintain power supply rejection greater than 60 dB for frequencies as high as 10 kHz while operating with a low headroom voltage.
