TLE4276GV50ATMA4 Equivalent & Substitute Parts

Part Overview

The TLE4276GV50ATMA4 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed for positive fixed 5V output at 400mA. This automotive-grade regulator operates across a wide input voltage range up to 40V with integrated protection features including over-current, over-temperature, reverse polarity, and short-circuit protection. The device is actively produced and AEC-Q100 qualified for automotive applications. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set.

Substitute Part Grouping Explanation

The TLE4276GV50ATMA3 qualifies as a parametric equivalent to the TLE4276GV50ATMA4 based on the following criteria:

All electrical parameters are identical: 5V fixed output, 400mA output current, 40V maximum input voltage, 0.5V dropout voltage, 200 µA quiescent current, and 54dB PSRR at 100Hz. Both devices operate across the same temperature range (-40°C to 150°C) and include identical protection features. Both maintain automotive-grade qualification with AEC-Q100 certification and ROHS3 compliance. The substitution is valid across the specified electrical and mechanical parameter set. The primary difference is packaging format: the main part uses Tape & Reel (TR) with P-TO220-5-122 supplier device package, while the substitute uses Cut Tape (CT) & Digi-Reel® with PG-TO263-5-1 supplier device package. Both use the same physical package type (TO-263-6, D2PAK with 5 Leads + Tab).
