BD950M5HFP-CTR

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

The BD950M5HFP-CTR is a fixed-output Low Dropout (LDO) regulator from ROHM Semiconductor's QuiCur series, designed for automotive applications. It features a TO-252-3 package and delivers a fixed 5.0V output with a maximum current of 500mA. The device supports an input voltage range from 6.2V to 42V, with a withstand voltage of up to 45V. Key electrical parameters include a typical dropout voltage of 0.39V at 0.3A load, 70dB ripple rejection, and line/load regulation of 0.1%. Quiescent current is typically 9.5µA, and it operates within a temperature range of -40°C to +125°C.

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

Verify the specific suffix 'CTR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to procurement. Ensure the selected component matches the required functional safety category if used in safety-critical automotive designs. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

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

Select this component for automotive designs requiring a fixed 5V rail with moderate current capacity. The TO-252-3 package offers thermal advantages over smaller footprints. Consider the 45V withstand voltage for protection against load dump conditions. Verify that the 0.39V dropout voltage meets system requirements under maximum load conditions.
