illustrate

should LP8720 is a versatile, programmable power management unit that is segmented to optimize solutions for power requirements. The device integrates a highly efficient dynamic voltage scaling 400 mA step-down DC/DC converter (DVS), five low noise low dropout (LDO) regulators, and a 400 kHz I 2 C compatible The interface allows a host controller to access internal control registers LP8720 。 should LP8720 It also has a programmable power-up sequence.

LDO regulators provide high PSRR, low noise ideal for power supply, ideal for analog and digital loads. The package will be the smallest 2.5mm x 2.0mm microSMD 20 solder ball package.
