GENERAL DESCRIPTION
The ADP5022 is a micro power management unit (micro PMU) that combines two high performance buck regulators and a low dropout regulator (LDO) in a tiny 16-ball 2.08 mm × 2.08 mm WLCSP to meet demanding performance and board space requirements.

FEATURES
    Input voltage range: 2.4 V to 5.5 V
    Tiny 16-ball, 2 mm × 2 mm WLCSP package
    Overcurrent and thermal protection
    Soft start
    Factory programmable undervoltage lockout on VDDA system supply of either 2.2 V or 3.9 V
    Factory programmable default output voltages for all 3 channels
    Buck1 and Buck2 key specifications
        Current mode architecture for excellent transient response
        3 MHz operating frequency
        Uses tiny multilayer inductors and capacitors
        Forced PWM and auto PWM/PSM modes
        Out-of-phase operation for reduced input filtering
        100% duty cycle low dropout mode
        24 μA typical quiescent current per channel, no switching
    LDO key specifications
        Stable with 1 μF ceramic output capacitors
        High PSRR
            60 dB up to 10 KHz
        Low output noise
            65 μV rms output noise at VOUT3 = 3.3 V
        Low dropout voltage: 150 mV @ 150 mA load
        11 μA typical ground current at no load

APPLICATIONS
    USB devices
    Handheld products
    Multivoltage power for processors, ASICS, FPGAs, and RF chipsets
