Analog Devices Inc. ADP5023ACPZ-R2

Overview

ADP5023ACPZ-R2 from Analog Devices is a compact three-output PMIC integrating two high-performance buck regulators and one low-dropout regulator. The device is designed for portable processors, handheld electronics, and mixed-signal systems that need two efficient switching rails plus one cleaner auxiliary rail.

As part of the ADP5023 product family, ADP5023ACPZ-R2 provides dual 800mA buck outputs, a 300mA LDO output, 3MHz switching operation, 2.3V to 5.5V input support, independent regulator enables, and a 24-lead 4mm x 4mm LFCSP package. For engineers reviewing the ADP5023ACPZ-R2 datasheet, ADP5023ACPZ-R2 pinout, ADP5023ACPZ-R2 application, or ADP5023ACPZ-R2 equivalent, this device is widely used in application processors, portable instruments, wireless modules, battery-powered consumer devices, mixed-signal boards, and compact embedded power architectures.

Technical Context

In portable embedded platforms, ADP5023ACPZ-R2 operates as a three-rail PMIC where two buck regulators provide efficient low-voltage rails and the LDO supplies a low-noise auxiliary rail for analog, RF, sensor, or peripheral circuitry.

The 3MHz switching frequency enables small inductors and capacitors, which helps reduce PCB area. Independent enables allow each rail to be controlled during system startup, shutdown, or low-power operating modes.

ADP5023ACPZ-R2 is useful when a system needs more switching-rail capability than a single buck-plus-LDO regulator but does not need the complexity of a larger PMIC with many outputs.

Key Specifications

Pinout & Package

The ADP5023ACPZ-1-R7 pinout includes buck input and switch pins, LDO input and output pins, enable pins, feedback or output setting pins, power-good functions, and exposed-pad ground.

For PCB design, each buck inductor and capacitor should be close to the PMIC, LDO capacitors should be placed near the output, and feedback traces should avoid switch-node noise.

Key Features

• Two 800mA buck regulators support efficient system rails.
• 300mA LDO provides low-noise auxiliary power.
• 3MHz switching reduces passive component size.
• Independent enables support sequencing.
• LFCSP package saves PCB area.
• Three-output architecture reduces external regulator count.

Applications

Equivalent & Alternatives

When evaluating a ADP5023ACPZ-1-R7 equivalent, engineers should compare number of outputs, buck current, LDO current, input range, switching frequency, package, and enable behavior.

Compared with ADP5024ACPZ-1-R7, ADP5023ACPZ-1-R7 should be selected when the ADP5023 three-output rail structure and suffix option match the design. ADP5023ACPZ-1-R7 vs ADP2140ACPZ3312R7 selection depends on whether the system needs two buck rails or a simpler buck-plus-LDO solution.

Quality

ADP5023ACPZ-1-R7 should be sourced as original Analog Devices components through traceable channels. Quality checks may include LFCSP package inspection, top-mark validation, solderability testing, and three-output electrical verification.

Production validation should include buck stability, LDO noise, startup sequencing, output accuracy, thermal behavior, and switching-layout review.

Availability

ADP5023ACPZ-1-R7 available at Aetrix Electronics and is suitable for portable, wireless, processor, and mixed-signal embedded systems requiring compact three-output PMIC supply support.

Supply support may include volume procurement planning, scheduled delivery arrangements, traceable sourcing management, and long-term supply support for OEM, industrial electronics, automotive electronics, and embedded product programs. Sample and NPI supply support, as well as urgent in-stock supply support, can also be arranged for prototype builds, pilot runs, and time-critical production needs.

For production builds, confirming suffix option, rail-current budget, package, lead time, lifecycle status, and sourcing continuity helps reduce procurement risk.
