“ LP8720 is a versatile, programmable power management unit with an optimized solution for blocking power needs. The device integrates a high-efficiency dynamic voltage amplification 400 mAh step-down DC/DC converter (DVS), five low-noise low-dropout (LDO) regulators and a 400 kHz I 2 C compatible The interface allows one main controller to access the internal control registers LP8720 。 “ LP8720 In addition, the function is programmable for on-power sequencing.

LDO regulators offer high power supply rejection ratios (PSRR) and low noise, making them ideal for powering both analog and digital loads. The package packages the smallest 2.5 mm × 2.0 mm micro SMD 20 bump balls.

Key specifications:

• DC/DC with programmable output voltage from 0.8V to 2.3V
• Automatic soft start, DC/DC
• 200 mV typical values for low dropout LDO at 300 mA
• Output voltage accuracy of 2% (typical) of LDO
