L5150BNTR

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

The L5150BNTR is a low dropout linear voltage regulator manufactured by STMicroelectronics, designed for automotive applications. It provides a fixed 5 V output with high accuracy of ±2% over a wide temperature range. The device operates within an input voltage range of 5.6 V to 40 V and features extremely low quiescent current. It includes internal output current limiting, short-circuit protection, overload protection, and thermal shutdown. The regulator requires only low-value ceramic capacitors on the output for stability and is qualified according to AEC-Q100 standards.

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

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the component meets AEC-Q100 Grade requirements for your target automotive application. Ensure input voltage does not exceed the maximum rating of 40 V during operation.

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

Select this regulator when a stable 5 V output is required from higher automotive bus voltages up to 40 V. Its low quiescent current makes it suitable for battery-powered systems where standby power consumption must be minimized. The integrated protections simplify design by reducing the need for external safety components.
