TPS79928DRVR

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

The TPS79928DRVR is a fixed-output low dropout linear regulator from the Texas Instruments TPS799 series. It provides a fixed 2.8 V output with a maximum continuous current of 200 mA. The device operates within an input voltage range of 2.7 V to 6.5 V and maintains a typical quiescent current of 40 uA. It features a typical dropout voltage of 100 mV at full load, with a maximum specified at 175 mV. Line regulation is rated at 0.02 %/V, while load regulation is 0.002 %/mA. The component supports surface mount installation in a 6-WSON package and functions reliably across an extended temperature range from -40 C to +125 C.

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

Verify the specific suffix DRVR against the manufacturer's official datasheet to confirm the exact packaging configuration and reel specifications. Ensure the ordering part number matches the required tape-and-reel quantity. Cross-reference the date code and manufacturing location with the latest production notices to guarantee component authenticity and consistency.

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

Select this component when a fixed 2.8 V rail is required with minimal noise impact on adjacent circuits. The low quiescent current makes it suitable for energy-efficient designs. Verify that the input voltage remains above the minimum threshold of 2.7 V under all operating conditions to maintain proper regulation and stability.

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

This device belongs to the TPS799 family of ultra-low noise LDOs. The family shares common architectural features such as high PSRR and low dropout characteristics. Variations within the series typically involve different fixed output voltages or alternative package options like SOT-23-5 or DSBGA, while maintaining similar electrical performance profiles for portable applications.

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

TPS79928DRVT serves as a direct functional substitute with identical electrical parameters but utilizes a cut-tape packaging format instead of the standard reel.
