TPS709B50DBVR Equivalent & Substitute Parts

Part Overview

The TPS709B50DBVR is an active linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. This device delivers a fixed 5V positive output at 150mA maximum current in a compact SOT-23-5 surface mount package. The part is currently in active production status with 8601 units in stock. Alternative equivalent parts are necessary to address supply chain flexibility, packaging preferences, and application-specific requirements such as automotive qualification or tape & reel delivery formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS709B50DBVR is determined by the following critical parameters:

• Fixed output voltage of 5V
• Output current capability of 150mA
• Maximum input voltage of 30V
• Operating temperature range of -40°C to 125°C
• SOT-23-5 package footprint compatibility
• Surface mount technology
• ROHS3 compliance

Substitute parts are grouped into two categories:

Parametric Equivalents (Texas Instruments TPS70950 Series): Parts TPS70950DBVR, TPS70950DBVT, and TPS70950QDBVRQ1 share identical electrical specifications with the main part. Differences exist only in packaging format (Cut Tape vs. Tape & Reel) and qualification level (standard vs. automotive AEC-Q100). These parts are direct functional replacements.

Manufacturer Recommended Equivalent (Diodes Incorporated AP7383-50WR-7): This part meets the core electrical requirements (5V output, 150mA current, 30V input maximum, -40°C to 125°C operation) and shares the same SOT-23-5 package footprint. Minor differences in dropout voltage (1.1V vs. 1.2V) and quiescent current (3 µA vs. 2.05 µA) fall within acceptable tolerance for most applications.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: TPS70950DBVR or TPS70950DBVT are direct replacements with identical electrical performance and ROHS3 compliance. Selection between these depends on packaging preference: Cut Tape & Digi-Reel format for TPS70950DBVR or Tape & Reel format for TPS70950DBVT. Both maintain active product status.

For Automotive Applications: TPS70950QDBVRQ1 is the appropriate selection when AEC-Q100 automotive qualification is required. This part maintains all electrical specifications of the main part while meeting automotive-grade reliability standards.

For Tape & Reel Delivery: TPS709B50DBVT provides the same Texas Instruments TPS709 series performance in Tape & Reel packaging format, suitable for high-volume automated assembly operations.

For Cross-Manufacturer Substitution: AP7383-50WR-7 from Diodes Incorporated is a viable alternative when supply from Texas Instruments is constrained. This part delivers equivalent 5V/150mA performance with marginally improved dropout voltage (1.1V vs. 1.2V) and slightly higher quiescent current (3 µA vs. 2.05 µA). Both devices are ROHS3 compliant and operate across the same temperature range. The SOT-25 package footprint is compatible with SOT-23-5 designs with minor PCB layout adjustment.

Frequently Asked Questions (FAQ)

Q: Can TPS70950DBVR be used as a direct replacement for TPS709B50DBVR?

A: Yes. Both parts deliver identical electrical specifications: 5V fixed output, 150mA current, 1.2V dropout voltage at 150mA, 2.05 µA quiescent current, and -40°C to 125°C operating range. The primary difference is packaging format. TPS70950DBVR is supplied in Cut Tape & Digi-Reel format, while TPS709B50DBVR is available in the same format. Both are ROHS3 compliant and in active production status.

Q: What is the difference between TPS70950DBVR and TPS70950QDBVRQ1?

A: Electrical specifications are identical. TPS70950QDBVRQ1 carries AEC-Q100 automotive qualification, making it suitable for automotive applications requiring this certification. Standard TPS70950DBVR is intended for industrial and consumer applications. Both share the same SOT-23-5 package and operating temperature range.

Q: Is AP7383-50WR-7 from Diodes Incorporated a suitable substitute?

A: AP7383-50WR-7 meets the core functional requirements: 5V output, 150mA current capability, 30V maximum input, and -40°C to 125°C operation. The dropout voltage is slightly lower (1.1V vs. 1.2V), and quiescent current is marginally higher (3 µA vs. 2.05 µA). Both parameters remain within acceptable ranges for most applications. The SOT-25 package is footprint-compatible with SOT-23-5 designs. This part is ROHS3 compliant and in active production.

Q: What packaging formats are available?

A: Texas Instruments TPS709B50DBVR and TPS70950DBVR are supplied in Cut Tape & Digi-Reel format. TPS709B50DBVT and TPS70950DBVT are supplied in Tape & Reel format for high-volume automated assembly. AP7383-50WR-7 is supplied in Tape & Reel format. Select based on assembly process requirements and order volume.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—TPS70950DBVR, TPS70950DBVT, TPS70950QDBVRQ1, TPS709B50DBVT, and AP7383-50WR-7—are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life).

Q: Which substitute should I select for high-volume production?

A: For high-volume automated assembly, select either TPS70950DBVT or TPS709B50DBVT, both supplied in Tape & Reel format. These formats are optimized for pick-and-place equipment. Alternatively, AP7383-50WR-7 from Diodes Incorporated is also available in Tape & Reel format and provides equivalent performance with improved dropout voltage characteristics.
