TLV2217-33KTPR Equivalent & Substitute Parts

Part Overview

The TLV2217-33KTPR is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3.3V output at 500mA in a TO-252-3 surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The device provides over current, over temperature, and over voltage protection suitable for power management applications requiring stable 3.3V regulation.

Substitute Part Grouping Explanation

Substitution for the TLV2217-33KTPR is determined by the following critical parameters: output voltage (3.3V fixed), output current capability (500mA), package type (TO-252-3 surface mount), input voltage rating (12V maximum), and protection features (over current, over temperature, over voltage). Parts meeting these specifications are classified as parametric equivalents. Parts with reduced output current or different output voltages are classified as manufacturer-recommended alternatives for applications with modified requirements.

Engineering Selection Recommendations

TLV2217-33KVURG3 is the parametric equivalent for direct replacement. This part maintains identical output voltage (3.3V), output current (500mA), input voltage rating (12V), voltage dropout (0.5V @ 500mA), package type (TO-252-3), and protection features. The part is in Last Time Buy status and remains ROHS3 compliant. This is the preferred substitute when full electrical and mechanical compatibility is required.

LP2950CDTX-3.3/NOPB is a manufacturer-recommended alternative for applications with reduced current requirements. While it maintains 3.3V output and TO-252-3 packaging, output current is limited to 100mA. This part is active and offers extended input voltage rating (30V) and wider operating temperature range (-40°C ~ 125°C). Selection of this part requires confirmation that 100mA output current is sufficient for the application.

TC1262-5.0VAB is a manufacturer-recommended alternative for applications requiring 5V output instead of 3.3V. This Microchip Technology part maintains 500mA output current and is active with extended temperature range (-40°C ~ 125°C). The package is TO-220-3 through hole, requiring PCB layout modification. This part is suitable only when 5V regulation is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can TLV2217-33KVURG3 be used as a direct replacement for TLV2217-33KTPR?

A: Yes. TLV2217-33KVURG3 is a parametric equivalent with identical output voltage (3.3V), output current (500mA), input voltage rating (12V), voltage dropout characteristics, and TO-252-3 package. No circuit modifications are required. The part is in Last Time Buy status, so procurement planning is recommended.

Q: What is the difference between TLV2217-33KTPR and LP2950CDTX-3.3/NOPB?

A: The primary difference is output current capability. TLV2217-33KTPR provides 500mA while LP2950CDTX-3.3/NOPB provides 100mA. Both maintain 3.3V output and TO-252-3 packaging. LP2950CDTX-3.3/NOPB is suitable only for applications with current requirements of 100mA or less.

Q: Can TC1262-5.0VAB replace TLV2217-33KTPR?

A: TC1262-5.0VAB is not a direct replacement. It provides 5V output instead of 3.3V and uses TO-220-3 through hole packaging instead of TO-252-3 surface mount. This part is suitable only when 5V regulation is acceptable and PCB layout can accommodate through hole mounting.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TLV2217-33KVURG3, LP2950CDTX-3.3/NOPB, and TC1262-5.0VAB are all ROHS3 compliant, matching the compliance status of the original TLV2217-33KTPR.

Q: What is the operating temperature range for each substitute?

A: TLV2217-33KTPR and TLV2217-33KVURG3 operate from 0°C to 125°C. LP2950CDTX-3.3/NOPB and TC1262-5.0VAB offer extended range from -40°C to 125°C, providing wider temperature coverage for demanding applications.
