BA18BC0WT

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

The BA18BC0WT is a fixed-output Low Dropout (LDO) regulator from ROHM Semiconductor, providing a stable 1.8 V output with a maximum current of 1 A. It operates within an input voltage range of 3 V to 16 V and features a typical dropout voltage of 0.3 V at 0.2 A load. The device maintains an output voltage accuracy of ±2% at 25°C and includes built-in overcurrent protection and thermal shutdown circuits for safety.

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

• Low saturation PNP output transistor design for minimal voltage drop
• Integrated overcurrent protection prevents damage during short-circuit conditions
• Thermal shut-down circuit activates to protect the device under overload or high-temperature scenarios

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

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

Verify the specific suffix and package variant when ordering, as the BA18BC0W series includes multiple pin configurations such as TO-220FP-5 and DPAK. Confirm RoHS compliance status and ensure the selected part matches the required thermal dissipation capabilities for the intended application environment.

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

Select this component when a fixed 1.8 V rail is required with up to 1 A load capability. Ensure the input voltage remains between 3 V and 16 V. Consider the thermal performance in the chosen package, as power dissipation depends on the difference between input and output voltages multiplied by the load current.
