Product details
Overview
ADP2140ACPZ3312R7 from Analog Devices is a compact power-management IC combining a 600mA high-efficiency buck regulator with a 300mA low-noise LDO regulator. The device is designed for portable and battery-powered products that need efficient conversion and a clean secondary rail in a very small total solution area.
As part of the ADP2140 product family, ADP2140ACPZ3312R7 provides 3MHz current-mode buck operation, low quiescent current, low shutdown current, high-PSRR LDO regulation, power-good indication, soft start, optional sequencing, and a 10-lead 3mm x 3mm LFCSP package. For engineers reviewing the ADP2140ACPZ3312R7 datasheet, ADP2140ACPZ3312R7 pinout, ADP2140ACPZ3312R7 application, or ADP2140ACPZ3312R7 equivalent, this device is widely used in mobile phones, personal media players, digital cameras, portable audio devices, battery-powered equipment, and compact mixed-signal embedded systems.
Technical Context
In portable systems, ADP2140ACPZ3312R7 operates as a two-output regulator where the 3MHz buck converter generates the efficient main rail and the LDO provides a low-noise auxiliary rail for analog, RF, sensor, or I/O circuitry.
The LDO can operate from an input as low as 1.65V, allowing it to be powered from the buck output to improve efficiency and reduce linear regulator dissipation. Power-saving variable-frequency operation improves battery life under light-load conditions.
ADP2140ACPZ3312R7 is commonly used when a design needs a compact buck-plus-LDO solution with soft-start, power-good indication, low dropout, and suffix-defined voltage options rather than two separate regulator ICs.

Pinout & Package
The ADP2140ACPZ3312R7 pinout includes buck input and switching pins, LDO input and output pins, enable controls, power-good output, feedback or output-setting pins, and exposed-pad ground.
For PCB design, the buck inductor and capacitors should be placed close to the LFCSP package, while the LDO output capacitor and feedback nodes should be routed away from switching noise.

Equivalent & Alternatives
When evaluating a ADP2140ACPZ3312R7 equivalent, engineers should compare buck current, LDO current, output-voltage option, quiescent current, LDO noise, package, power-good behavior, and sequencing needs.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADP5023ACPZ-1-R7 | Analog Devices PMIC with two 800mA buck regulators and one 300mA LDO, offering more switching rails than ADP2140. | Used when the system needs two buck outputs plus one LDO. | Compare rail count, output current, voltage options, package, and enable behavior. |
