BA30BC0FP-E2

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

The BA30BC0FP-E2 is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3 V output with a maximum current capacity of 1 A and an accuracy of ±2% at 25°C. The device operates within an input voltage range of 4 V to 16 V, requiring a minimum input of 4 V for regulation. Key electrical parameters include a typical dropout voltage of 0.3 V at 0.2 A load, a ripple rejection ratio of 55 dB, and a quiescent circuit current of 0.5 mA. It features thermal shutdown and overcurrent protection, operating reliably from -40°C to +105°C in a TO-252-3 surface-mount package.

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

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the TO-252-3 package matches your PCB footprint requirements. Check for end-of-life notices as some variants in this series are marked for obsolescence. Ensure input voltage remains above 4 V to maintain regulation. Validate thermal performance under maximum load conditions.

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

Select this component when a fixed 3 V output is required with high current capability up to 1 A. It is suitable for applications needing tight voltage accuracy of ±2%. Consider the 4 V minimum input voltage constraint; if lower headroom is needed, verify dropout characteristics. The TO-252-3 package offers robust thermal dissipation compared to smaller SOT packages. Ensure the application environment stays within the -40°C to +105°C operating temperature range.

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

The BA30BC0FP-E2 belongs to the BAxxBC0 series of low-saturation regulators from ROHM. This family shares common features such as 1 A output current, built-in protection circuits, and TO-252-3 packaging. Variants differ primarily by their fixed output voltage settings, ranging from 1.5 V to 10 V. The series is designed for general-purpose power management in consumer and industrial electronics.

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

Direct substitutes within the same series include BA25BC0FP-E2 (2.5 V), BA33BC0FP-E2 (3.3 V), and BA40BC0FP-E2 (4.0 V). Cross-series replacements require matching output voltage, current rating, and package type. Verify thermal resistance and protection features before substituting with other manufacturers' LDOs.
