BD50FA1FP3-ZTL

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

The BD50FA1FP3-ZTL is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 5.0 V output with a maximum continuous current of 100 mA. The device features a ±2.0% output voltage accuracy at 25°C and operates within an input voltage range of 8 V to 25 V. Key electrical parameters include a typical dropout voltage of 1.5 V at full load, a quiescent circuit current of 0.3 mA, and a line regulation of Vo x 0.005%. It incorporates built-in overcurrent protection and thermal shutdown circuits for reliability.

• Built-in overcurrent protection circuit prevents IC damage during output short circuits.
• Integrated thermal shutdown circuit protects against heat damage under overload conditions.
• Fixed output voltage design eliminates the need for external resistors.

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

• Digital home appliances
• General-purpose electronic equipment requiring stable 5V logic supply

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

Verify the exact part number suffix against official ROHM documentation to confirm specific packaging or tape-and-reel specifications. Ensure compatibility with RoHS directives if required by your manufacturing standards. Confirm that the SOT-89-3K package matches your PCB footprint requirements before finalizing procurement orders.

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

Select this component when a fixed 5.0 V rail is needed with moderate current capacity up to 100 mA. It is suitable for applications where space efficiency in an SOT-89-3K package is prioritized. Consider the 1.5 V typical dropout voltage to ensure sufficient input-to-output headroom. This regulator is not recommended for automotive use; select alternative automotive-grade parts for vehicle applications.

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

This LDO belongs to ROHM's standard series of fixed-output regulators designed for general consumer electronics. Unlike automotive-specific variants such as the BD50FA1MG-M, this model lacks functional safety certifications for vehicular systems. It serves as a cost-effective power management solution for non-critical digital loads in household devices.

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

Public confirmed substitute part numbers are not available in the provided data. For equivalent performance, consider other ROHM 100mA fixed 5V LDOs in compatible packages, ensuring verification of pinout and thermal characteristics.
