TLE72762EXUMA1 Equivalent & Substitute Parts

Part Overview

The TLE72762EXUMA1 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed to deliver a fixed 5V output at 300mA. This device is classified as a positive fixed output regulator with integrated protection features including over-current, over-temperature, and short-circuit protection. The part is packaged in a 14-LSSOP (0.154", 3.90mm Width) with exposed pad configuration, suitable for surface mount applications in automotive-grade environments.

The TLE72762EXUMA1 has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE72762EXUMA1 is determined by strict equivalence across the following critical parameters:

• Output voltage specification (5V fixed)
• Output current capability (300mA)
• Maximum input voltage rating (42V)
• Voltage dropout characteristics (0.5V @ 200mA)
• Quiescent current (30 µA)
• PSRR performance (60dB @ 100Hz)
• Protection feature set (Over Current, Over Temperature, Short Circuit)
• Operating temperature range (-40°C ~ 150°C)
• Automotive grade qualification (AEC-Q100)
• RoHS3 compliance

The TLE72762DATMA1 qualifies as a manufacturer-recommended substitute. Both parts share the same base product number (TLE72762) and maintain electrical equivalence across all specified parameters. The primary difference is packaging configuration: the main part uses 14-LSSOP with exposed pad, while the substitute uses TO-252-5 (DPAK) with tape & reel packaging.

Parameter Comparison

Engineering Selection Recommendations

The TLE72762DATMA1 is the manufacturer-recommended substitute for the obsolete TLE72762EXUMA1. Both devices maintain full electrical equivalence and share identical functional specifications across all critical parameters.

Selection between these parts is determined by PCB layout and thermal management requirements:

• The TLE72762EXUMA1 (14-LSSOP with exposed pad) is suitable for compact layouts requiring minimal board space with integrated thermal management through the exposed pad.
• The TLE72762DATMA1 (TO-252-5 DPAK) provides enhanced thermal dissipation capability through the larger tab contact and is preferred for applications with higher ambient temperatures or continuous high-current operation.

Both parts maintain AEC-Q100 automotive qualification and ROHS3 compliance. The TLE72762DATMA1 carries Last Time Buy status, indicating limited future availability. Current inventory levels support immediate procurement for both variants.

Frequently Asked Questions (FAQ)

Q: Are the TLE72762EXUMA1 and TLE72762DATMA1 electrically identical?

A: Yes. Both devices deliver identical electrical performance across all specified parameters including output voltage, current rating, dropout voltage, quiescent current, PSRR, and protection features. Substitution is electrically valid.

Q: What is the primary difference between these two parts?

A: The primary difference is packaging. The TLE72762EXUMA1 uses 14-LSSOP with exposed pad, while the TLE72762DATMA1 uses TO-252-5 (DPAK) configuration. This affects PCB footprint, thermal characteristics, and board layout requirements.

Q: Can I use the TLE72762DATMA1 as a direct replacement in existing designs?

A: Substitution requires PCB redesign due to different package footprints. The 14-LSSOP and TO-252-5 packages have different pin configurations and land patterns. Thermal performance may also differ, requiring evaluation of thermal management in your specific application.

Q: What is the significance of the product status difference?

A: The TLE72762EXUMA1 is classified as Obsolete, indicating end-of-life status with no further production. The TLE72762DATMA1 is Last Time Buy, meaning limited quantities remain available before discontinuation. For new designs or long-term production, secure inventory planning is essential.

Q: Are both parts suitable for automotive applications?

A: Yes. Both devices carry automotive grade classification and AEC-Q100 qualification, meeting automotive industry reliability and quality standards.

Q: What are the moisture sensitivity considerations?

A: The TLE72762EXUMA1 has MSL 3 (168 Hours), while the TLE72762DATMA1 has MSL 1 (Unlimited). The substitute part has superior moisture resistance and requires less stringent handling during storage and assembly.
