BD933M5WHFP-CTR

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

The BD933M5WHFP-CTR is a fixed-output Low Dropout (LDO) regulator from ROHM Semiconductor's QuiCur™ automotive series. It provides a stable 3.3V output with a maximum current of 0.5A. The device supports an input voltage range from 4.6V to 42V and withstands up to 45V. Key electrical parameters include a typical dropout voltage of 0.44V at 0.3A, 70dB ripple rejection, and ±2.0% output accuracy. It operates within a temperature range of -40°C to +125°C with a quiescent current of 9.5µA.

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

Verify the specific suffix 'CTR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the component matches the HRP5 package dimensions for PCB layout compatibility. Cross-reference the full part number against the latest ROHM product catalog to confirm availability and lifecycle status.

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

Select this component for automotive applications requiring direct battery connection due to its 45V withstand voltage. The QuiCur™ topology is suitable for designs needing fast transient response without large external capacitors. Consider the 0.44V dropout voltage for efficiency optimization. Verify that the 0.5A output current meets the load requirements of the target circuit.

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

This part belongs to the BD9xxM5-C series, designed specifically for automotive use. It features the QuiCur™ topology for enhanced dynamic response.
