E-L6932D2.5

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The L6932D2.5 is a high-performance Ultra Low Drop Output (ULDO) linear regulator manufactured by STMicroelectronics, designed to operate within an input voltage range of 2V to 14V. It provides a fixed output voltage of 2.5V with a maximum continuous load current capability of 2A and a short-circuit current limit of 2.5A. The device features a low quiescent current of 200µA at any load and ensures 1% voltage regulation accuracy. Key electrical parameters include a maximum drain-source on-resistance (Rdson) of 200mΩ and a ripple rejection of 75dB at 120Hz. It incorporates thermal shutdown protection limiting junction temperature to 150°C and includes Enable and Power Good control functions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'D' indicates the SO-8 package variant when sourcing replacements. Confirm that the component meets RoHS3 compliance requirements if applicable to your manufacturing standards. Check datasheet revision history for any updates to electrical characteristics or ordering information before finalizing procurement specifications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for designs requiring a fixed 2.5V rail from inputs between 2V and 14V. Ensure input capacitors exceed 10µF and output capacitors are selected based on transient response needs, considering stability with low ESR ceramic types. Evaluate thermal dissipation constraints carefully, as the SO-8 package limits continuous power handling based on ambient temperature and PCB copper area.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the L6932 family of 2A ULDO linear regulators from STMicroelectronics. The family includes fixed voltage variants (1.5V, 1.8V, 2.5V) and an adjustable version (L6932D1.2). All variants share the same SO-8 (4+4) package, pinout, and core protection features, differing primarily in their internal reference voltage setting.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same family include L6932D1.5TR and L6932D1.8TR for different fixed voltages. For adjustable output requirements, the L6932D1.2 series serves as a functional alternative. Verify pin compatibility and thermal performance when cross-referencing with other manufacturers' 2A LDOs.
