PM823 Dual Synchronous 1.5A/1.5A Step-down Buck Regulators with 525 mA LDO Rev.

4 23 June 2022 Product data sheet PUBLIC 1 Product overview The PM823 is an efficient low-cost power regulator.

It consists of two 1.5 A buck regulators and one 525 mA LDO.

The LDO can be powered by the buck converter output (≥1.6 V) to minimize the power loss and simplify the system thermal de-sign.

The PM823 is optimized for module applications.

It minimizes the PCB footprint and BOM cost.
