ADP5024ACPZ-R7

ADP5024 is a two high performance buck regulators and one low dropout (LDO) regulator. The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space. When the MODE pin is set high, the buck regulators operate in forced PWM mode. When the MODE pin is set low, the buck regulators operate in PWM mode when the load current is above a predefined threshold. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM), improving the light load efficiency. The two bucks operate out of phase to reduce the input capacitor requirement. The low quiescent current, low dropout voltage, and wide input voltage range of the LDO extends the battery life of portable devices. It is used in applications such as power for processors, ASICS, FPGAs, and RF chipsets, portable instrumentation and medical devices, space constrained devices.
