TPS79525DCQ

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

The TPS79525DCQ is a fixed-output low-dropout linear regulator from the Texas Instruments TPS795 series, housed in a surface-mount SOT-223-6 package. It provides a stable 2.5V output with a maximum continuous current capability of 500mA. The device operates within an input voltage range of 2.7V to 5.5V and maintains a typical dropout voltage of 110mV at full load. Quiescent current is specified at 265µA, supporting efficient power management. It features high power supply rejection ratio (PSRR) for noise-sensitive applications and includes comprehensive protection mechanisms such as overcurrent, thermal shutdown, reverse polarity, and undervoltage lockout.

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

Verify the specific suffix DCQ against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement channel sources genuine Texas Instruments components to guarantee electrical parameters match the published specifications. Confirm that the supply chain adheres to moisture sensitivity level handling requirements during storage and assembly processes.

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

Select this component when a fixed 2.5V rail is required with moderate current demands up to 500mA. It is suitable for designs prioritizing low noise and high line regulation over ultra-low quiescent current options. Consider the SOT-223-6 footprint constraints and thermal dissipation capabilities relative to the expected ambient operating temperature and load conditions.

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

This part belongs to the TPS795 family of ultralow-noise, high-PSRR LDOs designed for demanding RF and communication systems. Unlike general-purpose regulators, this series emphasizes noise suppression and transient response speed. The TPS79525 variant specifically targets applications needing a precise 2.5V reference or supply voltage with minimal ripple injection from the input source.

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

The TPS79525DCQR is a reel-packaged equivalent offering identical electrical characteristics and functionality. Verify that the tape-and-reel format aligns with automated assembly equipment requirements. No functional substitutes exist outside the TPS795 series without compromising noise or PSRR specifications.
