Product details
Overview
LP3907QTL-VXSS/NOPB from Texas Instruments is a multi-output PMIC integrating dual buck converters and dual LDO regulators for advanced application processors and FPGA-oriented portable systems. The device provides a 1A buck rail, a 600mA buck rail, and two 300mA LDO rails from a compact WQFN package.
As part of the TI LP3907 product family, LP3907QTL-VXSS/NOPB combines 2.8V to 5.5V input operation, an I2C-compatible serial interface, independent control of device functions, precision reference behavior, and configurable output options. For engineers reviewing the LP3907QTL-VXSS/NOPB datasheet, LP3907QTL-VXSS/NOPB pinout, LP3907QTL-VXSS/NOPB application, or LP3907QTL-VXSS/NOPB equivalent, this device is widely used in application processor rails, FPGA supplies, portable multimedia systems, handheld electronics, battery-powered modules, and compact multi-rail embedded architectures.
Technical Context
In portable processor systems, LP3907QTL-VXSS/NOPB operates as a four-output PMIC. The two buck regulators provide efficient high-current rails, while the two 300mA LDO regulators supply internal processor functions, I/O rails, or lower-noise auxiliary loads.
The I2C-compatible serial interface allows independent control of device functions and settings, making the PMIC useful where processors need rail control, power-state transitions, or configurable startup behavior.
LP3907QTL-VXSS/NOPB is commonly used where a 2.8V to 5.5V battery or system input must generate several coordinated rails in a 24-pin WQFN footprint without separate regulator ICs.

Equivalent & Alternatives
When evaluating a LP3907QTL-VXSS/NOPB equivalent, engineers should compare buck current, LDO current, I2C control, OTP configuration, package, sequencing, dynamic voltage scaling, and automotive qualification needs.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LP873347RHDT | Same LP8733 configuration family with a different packing or orderable suffix. | Used when the same configured PMIC is needed in another packing option. | Compare exact orderable suffix, package, reel/tray format, and availability. |
| TPS65023 | Texas Instruments multi-output PMIC with several DC-DC and LDO rails but different configuration and control behavior. | Used in embedded processor platforms requiring multi-rail power management. | Compare rail count, current ratings, I2C features, package, and default voltage settings. |
Compared with LP873347RHDT, LP3907QTL-VXSS/NOPB should be selected when its exact orderable suffix and configuration match the board requirement. LP3907QTL-VXSS/NOPB vs TPS65023 selection depends on rail current, I2C control needs, OTP defaults, package, and processor power-tree architecture.
Quality
LP3907QTL-VXSS/NOPB should be sourced as original Texas Instruments components through traceable supply channels. Quality checks may include VQFN inspection, top-mark validation, solderability testing, and verification of buck, LDO, and I2C functions.
Production validation should include rail sequencing, I2C configuration, output voltage accuracy, dynamic voltage scaling, load-transient response, LDO stability, thermal behavior, and startup timing.
Availability
LP3907QTL-VXSS/NOPB available at Aetrix Electronics and is suitable for automotive, industrial, camera, infotainment, and processor-based embedded systems requiring configurable multi-rail 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 OTP configuration, orderable suffix, package, rail-current budget, software interface, lifecycle status, and sourcing continuity helps reduce procurement risk.
