TPS76801QPWPREP Equivalent & Substitute Parts

Part Overview

The TPS76801QPWPREP is a linear voltage regulator IC from Texas Instruments designed for positive adjustable output applications. This single-output regulator delivers 1A of continuous current with adjustable output voltage ranging from 1.2V to 5.5V. The device is housed in a 20-HTSSOP surface mount package and includes integrated protection features for over-current, over-temperature, and reverse polarity conditions. With active product status and full RoHS3 compliance, the TPS76801QPWPREP serves as a primary component in power management circuits. Substitute parts are identified to address packaging format variations and automotive-grade qualification requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS76801QPWPREP are identified based on strict electrical and mechanical parameter matching. All substitute candidates maintain identical specifications across the following critical parameters: output configuration (positive), output type (adjustable), number of regulators (1), input voltage maximum (10V), output voltage range (1.2V to 5.5V), output current (1A), quiescent current (125 µA), PSRR (60dB at 1kHz), control features (Enable, Power Good), protection features (Over Current, Over Temperature, Reverse Polarity), operating temperature range (-40°C to 125°C), mounting type (Surface Mount), and package type (20-PowerTSSOP). Substitution differences are limited to packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and automotive qualification status where applicable. All substitute parts share the same base product number (TPS76801) and maintain RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full RoHS3 compliance, ensuring long-term availability and environmental regulatory adherence. The TPS76801QPWPREP and TPS76801QPWPR are functionally identical standard-grade devices differentiated only by packaging format: Tape & Reel versus Cut Tape & Digi-Reel. Selection between these two depends on procurement and assembly requirements rather than electrical performance.

The TPS76801QPWPRQ1 is qualified to AEC-Q100 automotive standards and carries automotive-grade designation. This variant is suitable for applications requiring automotive qualification compliance. The higher moisture sensitivity level (MSL 3 versus MSL 2) reflects automotive-grade handling requirements and does not affect electrical performance in standard operating conditions.

Component selection should be based on application requirements: standard industrial applications may use TPS76801QPWPREP or TPS76801QPWPR, while automotive applications requiring AEC-Q100 qualification must use TPS76801QPWPRQ1.

Frequently Asked Questions (FAQ)

Q: Are TPS76801QPWPREP, TPS76801QPWPR, and TPS76801QPWPRQ1 electrically interchangeable?

A: Yes. All three parts deliver identical electrical performance across all specified parameters including output voltage range (1.2V to 5.5V), output current (1A), quiescent current (125 µA), PSRR (60dB at 1kHz), and protection features. Differences are limited to packaging format and automotive qualification status.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel packaging provides components on cut tape segments or alternative reel formats, typically for lower-volume or mixed-component orders. Both formats contain identical components in the same 20-PowerTSSOP package.

Q: When should I use the TPS76801QPWPRQ1 automotive-grade variant?

A: Use TPS76801QPWPRQ1 when your application requires AEC-Q100 automotive qualification compliance. This variant is specifically qualified for automotive environments and meets automotive industry standards. Standard-grade variants (TPS76801QPWPREP and TPS76801QPWPR) are not qualified for automotive applications.

Q: Do all three parts have the same moisture sensitivity level?

A: No. TPS76801QPWPREP and TPS76801QPWPR have MSL 2 (1 Year), while TPS76801QPWPRQ1 has MSL 3 (168 Hours). MSL rating indicates moisture sensitivity during storage and handling. Higher MSL numbers require more stringent moisture control during storage and assembly processes.

Q: Can I substitute TPS76801QPWPREP with TPS76801QPWPRQ1 in a non-automotive application?

A: Yes. TPS76801QPWPRQ1 is electrically and mechanically compatible with TPS76801QPWPREP. The automotive qualification is an additional certification that does not restrict use in standard applications. However, the higher MSL rating requires appropriate moisture control during storage and assembly.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three variants are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic components.
