should LP8720 is a versatile, programmable power management unit that is chunked to optimize solutions for power needs. The device integrates a high-efficiency dynamic voltage amplification 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 master controller to access the internal control registers LP8720 。 should LP8720 In addition, there is a programmable power-on sequence.

LDO regulators offer high PSRR and low noise, making them ideal for power supply to analog and digital loads. The package will be the smallest 2.5 mm x 2.0 mm micro SMD 20 bump package.

Key specifications:

• Programmable output voltages from 0.8V to 2.3V DC/DC
• Automatic soft-start DC/DC
• 200 mV typical value of 300 mA at the voltage difference of LDO
• 2% (typical) voltage accuracy of the output LDO
