TL750L05CLPRE3 Equivalent & Substitute Parts

Part Overview

The TL750L05CLPRE3 is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. This positive fixed output regulator delivers 150mA at 5V and operates across an input voltage range up to 26V. The device is in Active product status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are necessary to address inventory availability, lead time constraints, or specific application requirements while maintaining electrical and mechanical compatibility within the TO-92-3 package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Package / Case: TO-92-3 (TO-226-3) Formed Leads for Through Hole mounting
• Output Configuration: Positive
• Output Type: Fixed
• Voltage - Output (Min/Fixed): 5V
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

• Current - Output: Substitute parts may have equal or greater output current capacity
• Voltage - Input (Max): Substitute parts may have equal or greater maximum input voltage
• Voltage Dropout (Max): Substitute parts may have equal or lower dropout voltage
• Operating Temperature: Substitute parts may have equal or extended temperature range
• PSRR and Quiescent Current: Variations permitted based on manufacturer design

The TL750L05CLPRE3 specifies 150mA output current. Substitute parts with 100mA output current are listed as alternatives for applications where the full 150mA capacity is not required. All substitute parts maintain the 5V fixed output, TO-92-3 package, and positive output configuration.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent: TL750L05CLPR is the direct substitute for TL750L05CLPRE3. Both parts are manufactured by Texas Instruments with identical electrical specifications, including 150mA output current, 0.6V dropout voltage at 150mA, and 65dB PSRR. Both maintain Active product status and ROHS3 compliance. This substitution requires no design modification.

Reduced Current Capacity Alternatives: L78L05ACZTR, LM2931AZ-5.0RAG, LM2931AZ-5.0RPG, LM2931Z-5.0RAG, and LM2931Z-5.0RPG are suitable substitutes for applications where output current requirements do not exceed 100mA. These parts maintain the 5V fixed output, TO-92-3 package, and positive output configuration. All are Active status with ROHS3 compliance. The onsemi LM2931 series offers extended operating temperature range (-40°C to 125°C) and superior PSRR (90dB) compared to the main part. The STMicroelectronics L78L05ACZTR supports higher maximum input voltage (30V) but features lower PSRR (49dB).

Compliance Verification: All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can I use a 100mA rated substitute in place of the TL750L05CLPRE3 which is rated for 150mA?

A: Substitution is permissible only if your application circuit draws 100mA or less from the regulator output. The 100mA-rated alternatives (L78L05ACZTR, LM2931 series) will function correctly at reduced current levels. If your design requires the full 150mA capacity, use TL750L05CLPR or maintain the original TL750L05CLPRE3.

Q: Are all substitute parts pin-compatible with the TL750L05CLPRE3?

A: Yes. All listed substitute parts use the TO-92-3 (TO-226-3) package with formed leads, maintaining identical pin configuration and Through Hole mounting compatibility. Direct PCB substitution is possible without layout modification.

Q: What is the difference between the onsemi LM2931 variants (AZ vs. Z, RAG vs. RPG)?

A: The LM2931AZ and LM2931Z designations indicate different temperature grades and manufacturing processes within the onsemi LM2931 family. The RAG and RPG suffixes denote packaging and tape reel specifications. All four onsemi variants listed (LM2931AZ-5.0RAG, LM2931AZ-5.0RPG, LM2931Z-5.0RAG, LM2931Z-5.0RPG) share identical electrical specifications: 100mA output, 0.6V dropout at 100mA, -40°C to 125°C operating range, and 90dB PSRR.

Q: Does the STMicroelectronics L78L05ACZTR offer any advantages over the onsemi LM2931 series?

A: The L78L05ACZTR supports a higher maximum input voltage (30V vs. 26V). However, it features lower PSRR (49dB vs. 90dB) and higher quiescent current (5.5mA vs. 1mA). Selection depends on whether your application requires the extended input voltage range or prioritizes low noise and low quiescent current performance.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Cut Tape (CT) packaging with TO-92-3 (TO-226-3) formed leads, matching the original TL750L05CLPRE3 packaging specification.

Q: What is the impact of the extended operating temperature range (-40°C to 125°C) offered by the onsemi LM2931 series?

A: The onsemi LM2931 series extends the lower operating temperature limit from 0°C to -40°C compared to the TL750L05CLPRE3. This provides additional thermal margin for applications operating in cold environments. If your design operates only within 0°C to 125°C, this extended range provides no functional benefit but may be advantageous for future design flexibility.
