TLV71209DBVR Equivalent & Substitute Parts

Part Overview

The TLV71209DBVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 0.9V at 300mA in a surface-mount SOT-23-5 package. The device is currently in active production status with 4190 units available in inventory. Alternative part numbers are necessary when tape & reel packaging is unavailable or when sourcing from alternative manufacturers is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV71209DBVR is determined by the following critical parameters:

• Fixed output voltage of 0.9V
• Output current capability of 300mA
• Maximum input voltage of 5.5V or greater
• Surface-mount package compatibility (SOT-23-5 or SOT-25 pinout equivalent)
• Positive output configuration with single regulator
• Enable control feature
• Active product status

Substitute parts must maintain electrical compatibility across these parameters. Packaging format differences (tape & reel versus cut tape) do not affect functional equivalence. Minor variations in quiescent current, PSRR, or maximum operating temperature are acceptable provided the substitute meets or exceeds the minimum requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

TLV71209DBVT is a direct parametric equivalent to TLV71209DBVR, differing only in packaging format. Both parts are manufactured by Texas Instruments, maintain identical electrical specifications, and support the full operating temperature range of -40°C to 125°C. Selection between these two should be based on packaging availability and procurement requirements.

AP7343-09W5-7 from Diodes Incorporated is functionally compatible with the TLV71209DBVR for applications where the maximum input voltage requirement does not exceed 5.25V and the operating temperature does not exceed 85°C. This substitute offers improved PSRR performance (75dB versus 68dB at 1kHz) and maintains the same output voltage and current specifications. The SOT-25 package is mechanically compatible with SOT-23-5 footprints in most PCB designs.

All three parts carry active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can TLV71209DBVT be used as a direct replacement for TLV71209DBVR?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, output voltage, current rating, and operating temperature range. The only difference is packaging format (cut tape versus tape & reel). Functional performance is equivalent.

Q: What are the limitations of using AP7343-09W5-7 as a substitute?

A: The AP7343-09W5-7 has a lower maximum input voltage (5.25V versus 5.5V) and a reduced maximum operating temperature (85°C versus 125°C). Applications requiring input voltages above 5.25V or operating temperatures above 85°C must use TLV71209DBVR or TLV71209DBVT.

Q: Are the SOT-23-5 and SOT-25 packages pin-compatible?

A: Both packages use five pins in a surface-mount configuration with compatible pinout arrangements for this regulator topology. PCB footprints designed for SOT-23-5 can accommodate SOT-25 devices in most applications. Verify pinout alignment with the specific datasheet before assembly.

Q: Do all three parts meet the same compliance standards?

A: Yes. TLV71209DBVR, TLV71209DBVT, and AP7343-09W5-7 are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All three carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: Which substitute offers the best performance characteristics?

A: AP7343-09W5-7 provides superior PSRR performance (75dB versus 68dB at 1kHz). However, this advantage is only applicable in applications where the lower input voltage maximum (5.25V) and reduced operating temperature range (-40°C to 85°C) are acceptable constraints.
