TPS76328DBVR Equivalent & Substitute Parts

Part Overview

The TPS76328DBVR is a linear voltage regulator IC manufactured by Texas Instruments, classified as a Power Management (PMIC) device. It delivers a fixed positive output of 2.8V at 150mA in a surface-mount SOT-23-5 package. The device is currently in active product status with 26,400 units in stock. Alternative models become necessary when the primary part faces supply constraints, obsolescence of related variants, or when design requirements permit functional equivalents from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS76328DBVR is determined by the following criteria:

Primary Substitution Parameters:

• Fixed output voltage of 2.8V
• Output current rating of 150mA
• Maximum input voltage of 10V
• SOT-23-5 package footprint compatibility
• Surface-mount technology
• Enable control feature
• Over-current protection

Substitution Categories:

Parametric Equivalents (Texas Instruments): Parts TPS76328DBVT, TPS76428DBVR, and TPS76428DBVT meet all electrical specifications and package requirements. These devices share identical output voltage, current rating, input voltage limits, and protection features. Differences in product status (active vs. obsolete) and packaging format (tape & reel vs. cut tape) do not affect functional substitution.

Manufacturer-Recommended Alternatives: Parts S-1200B28-M5T1U (ABLIC Inc.) and XC6209B282MR-G (Torex Semiconductor Ltd) provide functional equivalence with identical output voltage, current rating, and input voltage specifications. These alternatives maintain SOT-23-5 package compatibility and surface-mount configuration. Variations in quiescent current, PSRR, dropout voltage, and operating temperature range are secondary parameters that do not prevent substitution when the primary electrical and mechanical criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: TPS76328DBVR remains the preferred choice as the active, in-stock reference device with full temperature range operation (-40°C to 125°C) and established supply availability (26,400 units).

Texas Instruments Alternatives: TPS76428DBVR and TPS76428DBVT are active-status alternatives from the same manufacturer, providing continuity of supply and support. TPS76328DBVT is not recommended for new designs due to obsolete product status, though it remains functionally equivalent for legacy applications.

Cross-Manufacturer Alternatives: S-1200B28-M5T1U (ABLIC Inc.) and XC6209B282MR-G (Torex Semiconductor Ltd) are active products suitable for substitution when Texas Instruments parts are unavailable. Both maintain ROHS3 compliance and functional equivalence. Selection between these alternatives depends on supply availability and design temperature requirements. S-1200B28-M5T1U offers superior quiescent current performance (1 µA vs. 100 µA), while XC6209B282MR-G provides higher PSRR (70dB at 10kHz). Both alternatives operate within -40°C to 85°C range, which is narrower than the primary device.

Frequently Asked Questions (FAQ)

Q: Can TPS76328DBVT be used as a direct replacement for TPS76328DBVR?

A: Yes. Both devices are parametrically identical in electrical specifications and package configuration. The obsolete product status of TPS76328DBVT does not affect functional compatibility. However, for new designs, TPS76328DBVR or TPS76428DBVR are preferred due to active product status and assured long-term availability.

Q: What is the difference between TPS76328DBVR and TPS76428DBVR?

A: Both parts are functionally equivalent with identical output voltage (2.8V), output current (150mA), input voltage limits (10V max), and package configuration (SOT-23-5). The primary difference is the base product number designation (TPS76328 vs. TPS76428). Both are active products suitable for new designs.

Q: Are ABLIC S-1200B28-M5T1U and Torex XC6209B282MR-G compatible with TPS76328DBVR?

A: Yes. Both devices meet the core substitution criteria: 2.8V fixed output, 150mA current rating, 10V maximum input voltage, and SOT-23-5 package footprint. Both are ROHS3 compliant and active products. Design considerations include narrower operating temperature range (-40°C to 85°C vs. -40°C to 125°C) and different quiescent current and PSRR characteristics.

Q: What is the package difference between SOT-23-5 and SOT-25?

A: SOT-23-5 and SOT-25 are both five-pin surface-mount packages with identical pin pitch and footprint compatibility. XC6209B282MR-G uses SOT-25 designation but maintains mechanical and electrical compatibility with SOT-23-5 devices in this application.

Q: Which substitute part offers the lowest power consumption?

A: S-1200B28-M5T1U provides the lowest quiescent current at 1 µA, compared to 100 µA for TPS76328DBVR and 50 µA for XC6209B282MR-G. This characteristic is relevant for battery-powered or low-power standby applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—TPS76328DBVT, TPS76428DBVR, TPS76428DBVT, S-1200B28-M5T1U, and XC6209B282MR-G—are ROHS3 compliant and REACH unaffected.
