ADP5023ACPZ-R7 (ANALOG DEVICES)

The ADP5023ACPZ-R7 is a two high performance Buck Regulator 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 ADP5023 LDO extends the battery life of portable devices. The ADP5023 LDO maintains power supply rejection greater than 60dB for frequencies as high as 10kHz while operating with a low headroom voltage. Regulators in the ADP5023 are activated though dedicated enable pins.
