BD50C0AHFP-CTR

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

The BD50C0AHFP-CTR is a low saturation linear regulator (LDO) from ROHM Semiconductor, designed for automotive applications. It provides a maximum output current of 1A with a fixed voltage output type and ±1.0% accuracy at 25°C. The device withstands a maximum voltage of 35V, operating within an input voltage range of 6V to 26.5V. Key electrical parameters include a typical dropout voltage of 0.3V at 500mA load, 55dB ripple rejection, and a circuit current of 0.5mA. It features thermal shutdown and overcurrent protection but lacks shutdown, soft start, or discharge functions. The component operates between -40°C and 125°C in an HRP5 package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated overcurrent protection prevents IC damage during output short circuits.
• Thermal shutdown circuit protects the IC from thermal destruction under overload conditions.
• Low saturation design ensures stable regulation with minimal voltage drop at high currents.

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

• Automotive power supply systems requiring functional safety support
• High-side regulator applications in vehicle electronics
• Power management for components needing 1A continuous current

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

Verify the specific suffix 'CTR' corresponds to the taping packaging format with a quantity of 2000 units per reel. Confirm RoHS compliance status and ensure the HRP5 package dimensions match your PCB layout requirements. Cross-reference the AEC-Q100 qualification data if automotive reliability standards are mandatory for your design implementation.

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

Select this LDO when a fixed output with high precision is required alongside robust protection mechanisms. The 35V withstand voltage allows compatibility with standard automotive battery systems. Ensure the thermal management solution accommodates the power dissipation at full 1A load, as the device lacks active shutdown features. Verify that the 0.5mA quiescent current meets system standby requirements.
