BA30BC0WFP-E2

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

The BA30BC0WFP-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3 V output with a maximum load current of 1 A. The device operates within an input voltage range of 4 V to 16 V and features a typical dropout voltage of 0.3 V at 0.2 A. Output voltage accuracy is specified at ±2.0% at 25°C. It includes built-in overcurrent protection and thermal shutdown circuits for safety. The regulator is housed in a TO-252-5 (PPAK-5) surface-mount package and supports an operating temperature range from -40°C to +105°C.

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

Verify the exact suffix against official ROHM documentation, as variations may exist between FP and WFP packages. Confirm availability status, as some BAxxBC0 variants are marked as end-of-life or obsolete. Ensure the specific part number matches the required pinout and thermal performance for your PCB layout. Cross-reference datasheets for precise electrical limits before finalizing procurement decisions.

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

Select this component when a fixed 3V output is required with high current capability up to 1A. The low dropout voltage makes it suitable for applications where input voltage is close to the output level. Consider the TO-252-5 package for adequate thermal dissipation in space-constrained designs. Verify that the input voltage does not exceed the maximum rating of 16V to ensure safe operation.
