BA18BC0WFP-E2

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

The BA18BC0WFP-E2 is a fixed-output Low Dropout (LDO) regulator manufactured by ROHM Semiconductor. It provides a stable 1.8 V output with a maximum current capacity of 1 A. The device features an input voltage range from 3 V to 16 V and maintains an output voltage accuracy of ±2% at 25°C. Typical dropout voltage is 0.3 V at 0.2 A load, with a maximum of 500 mV. Circuit current is 0.5 mA. It includes thermal shut-down and overcurrent protection. Operating temperature ranges from -40°C to +105°C. The component is housed in a TO-252-5 package.

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

Verify the specific suffix E2 for RoHS compliance and lead time requirements. Confirm availability status as some listings indicate end-of-life or limited stock. Ensure the TO-252-5 package matches your PCB footprint. Check for alternative fixed voltage variants within the BAxxBC0W series if 1.8V is not strictly required.

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

Select this component when a fixed 1.8V rail is needed with 1A capability. The low dropout characteristic suits applications with narrow input-output voltage differentials. Verify that the 0.5mA quiescent current meets system standby requirements. Ensure adequate thermal dissipation for the TO-252-5 package under maximum load conditions.

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

This part belongs to the BAxxBC0W series of 1A variable/fixed output LDO regulators. The series offers various fixed output voltages ranging from 1.5V to 10V. All members share similar protection features including thermal shutdown and overcurrent limiting. The BA18BC0WFP-E2 specifically targets the 1.8V application segment within this family.

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

Other BAxxBC0WFP-E2 variants with different fixed output voltages (e.g., BA15BC0WFP-E2, BA25BC0WFP-E2) are pin-compatible. Ensure the replacement voltage matches the load requirement. Verify that the input voltage range of the substitute supports the system's supply rails.
