Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for TPS79425DGNR

TPS79425DGNR

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

The TPS79425DGNR is a fixed-output low-dropout linear regulator from Texas Instruments, providing a stable 2.5 V output with a maximum load current of 250 mA. It operates within an input voltage range of 1.8 V to 6.5 V and features a typical quiescent current of 170 µA. The device ensures high power-supply rejection ratio (PSRR) and ultralow noise performance, making it suitable for sensitive analog circuits. It is housed in an 8-pin HVSSOP package with an exposed pad for thermal management.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

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

Verify the specific revision code on the component marking against the official datasheet to ensure compatibility. Confirm that the 8-pin HVSSOP package dimensions match your PCB footprint requirements. Check for any end-of-life notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

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

Select this component when ultralow noise and high PSRR are critical for the application. Ensure the input voltage remains within the specified 1.8 V to 6.5 V range. Consider the thermal dissipation capabilities of the exposed pad package if operating near maximum load currents.

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

This part belongs to the TPS794 series of low-dropout regulators designed for high-performance applications. It complements other variants in the family by offering a fixed 2.5 V output in a compact surface-mount package. The series is engineered for portable electronics where power efficiency and signal purity are paramount.

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

Check for direct pin-compatible substitutes within the same TPS794 family. Verify that alternative parts maintain similar noise specifications and PSRR levels. Ensure the replacement package matches the 8-HVSSOP form factor.
