TLE4276DV50ATMA2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TLE4276DV50ATMA2 is an Infineon OPTIREG™ linear low-drop voltage regulator (LDO) designed for automotive electronics. It regulates input voltages up to 40 V to a fixed 5.0 V output with high accuracy. The device supports a maximum output current of 400 mA and features a very low static current consumption of 200 µA. It includes an inhibit input that reduces current draw below 10 µA when deactivated. The component offers comprehensive protection against short circuits, overtemperature conditions, and reverse polarity connections. It is qualified to AEC-Q100 standards and operates within a temperature range of -40°C to 150°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering code and package variant during procurement, as the TLE4276 series includes multiple pin-compatible options. Confirm availability status, as this specific part number may be subject to end-of-life or obsolescence notices from the manufacturer. Ensure compliance with RoHS3 specifications and check for any recent packaging changes documented in production change notifications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5 V rail is required with high current capability and robust automotive-grade protection. The PG-TO252-5-1 package suits surface-mount applications needing efficient heat dissipation. Consider the inhibit feature if system-level power management requires active shutdown capabilities. Verify input voltage ranges do not exceed the 40 V absolute maximum rating under all operating transients.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the Infineon OPTIREG™ linear family, specifically the TLE4276 series of low-drop regulators. It is distinct from the TLE4276-2 series which offers tighter voltage tolerances. The 'DV' suffix indicates the TO-252 surface-mount package, while 'V50' denotes the fixed 5.0 V output version. The 'ATMA2' suffix specifies the tape-and-reel packaging format for automated assembly.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

TLE4276DV50ATMA1 is a similar package variant within the same family. TLE4276GV50ATMA3 offers the same electrical performance in a PG-TO263-5-1 package.
