TLV70225DBVR

Product Overview

The TLV70225DBVR from Texas Instruments is a fixed-output linear voltage regulator with a positive output configuration intended for compact surface-mount designs. The device provides a 2.5 V output from an input voltage up to 5.5 V and can deliver 300 mA to a single regulated load. Its maximum dropout voltage is 0.38 V at 300 mA. The regulator includes an enable control and integrates protection against overcurrent, overtemperature, reverse polarity, and under-voltage lockout. With a 55 µA quiescent current, 370 µA maximum supply current, and 68 dB PSRR at 1 kHz, it is suited to space-constrained board layouts that require a fixed-voltage supply.

Key Features

• Positive fixed 2.5 V output with 300 mA output current in a single-output linear regulator configuration.
• Maximum input voltage of 5.5 V and dropout voltage of 0.38 V at 300 mA.
• Enable control for active output management.
• Protection features include overcurrent, overtemperature, reverse polarity, and under-voltage lockout.
• 55 µA quiescent current and 370 µA maximum supply current.
• 68 dB power-supply rejection at 1 kHz.
• Operating temperature range of -40°C to 125°C junction temperature.
• Surface-mount package identified as SC-74A, SOT-753, and SOT-23-5.

Applications

• Regulated 2.5 V supply for logic or sensor circuits in compact electronic assemblies.
• Post-regulation of a higher positive input rail to provide a fixed voltage for analog or digital subsystems.
• Single-output power distribution for embedded control boards that use enable control and integrated protection.
• Space-constrained surface-mount designs where a SOT-23-5 linear regulator is needed for a 300 mA load.

Design & Procurement Notes

When selecting the TLV70225DBVR, verify that the input voltage remains within the 5.5 V maximum and that the input-to-output difference accommodates the 0.38 V dropout at the required 300 mA load. The enable control requires a system-level decision on how the output is enabled and disabled during operation. Because the device provides a fixed 2.5 V output, it is appropriate for designs where the load voltage does not require adjustment. Thermal design should consider the junction temperature range of -40°C to 125°C. The integrated overcurrent, overtemperature, reverse polarity, and UVLO protections are relevant to fault conditions, but external input and output filtering should still be evaluated for the specific supply environment. The 68 dB PSRR at 1 kHz and 55 µA quiescent current are relevant when comparing noise rejection and low-current requirements. Confirm the intended package designation, SC-74A, SOT-753, or SOT-23-5, matches the board footprint.
