BA33C18FP-E2

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

The BA33C18FP-E2 is a dual-channel linear voltage regulator IC from ROHM Semiconductor. It provides two fixed output voltages of 1.8V and 3.3V, each capable of delivering up to 1A of output current. The device operates with an input voltage range of 4.1V to 16V and features a typical dropout voltage of 250mV at full load. Packaged in a TO-252-5 surface-mount case, it integrates thermal shutdown and overcurrent protection for reliable operation in space-constrained designs.

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

Verify the exact suffix and package variant against the official ROHM datasheet before ordering. Confirm that the dual-output configuration matches the specific system requirements. Check for end-of-life status or alternative recommendations if the component is discontinued. Ensure compatibility with the intended PCB footprint and thermal management strategy.

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

Select this component when a single package solution is required for generating both 1.8V and 3.3V rails. It is appropriate for designs where board space is limited and synchronized regulation is beneficial. Consider the input voltage range and thermal dissipation capabilities relative to the expected load currents and ambient temperature conditions.

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

This part belongs to ROHM's family of dual-channel LDO regulators designed for compact power management. It simplifies circuit design by replacing two separate single-channel regulators with one integrated unit. The TO-252-5 package offers a balance between current handling capacity and small form factor for surface-mount assembly.

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

Check for direct pin-compatible substitutes within the same ROHM series. Verify that any replacement maintains the dual-output architecture and identical voltage levels. Ensure thermal and electrical specifications meet or exceed the original requirements for safe integration.
