BD25GA3WEFJ-E2

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

The BD25GA3WEFJ-E2 is a high-accuracy fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 2.5 V output with a maximum current capacity of 300 mA. The device operates within an input voltage range of 4.5 V to 14 V and supports a maximum withstand voltage of 15 V. Key electrical parameters include a typical dropout voltage of 0.6 V at full load, a quiescent current of 600 µA, and a load regulation of 1.5%. The output voltage accuracy is specified at ±1.0% at 25°C. It features thermal shutdown, overcurrent protection, and a shutdown function that reduces circuit current to 0 µA.

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

• Integrated overcurrent protection and thermal shutdown circuits to prevent IC damage during short-circuit or overload conditions.
• Shutdown function allows for zero current consumption when the circuit is disabled, supporting power management requirements.
• Compatible with ceramic output capacitors, facilitating miniaturization and extended lifespan of the host equipment.

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

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

Verify the complete part number including the suffix -E2 to ensure compliance with specific packaging and environmental standards. Confirm the HTSOP-J8 package type matches your PCB footprint design. Check for RoHS compliance status as indicated in official documentation before finalizing procurement specifications.

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

Select this component when a fixed 2.5 V rail is required with moderate current demands up to 300 mA. Ensure the input voltage remains between 4.5 V and 14 V to maintain proper regulation. Consider the 600 µA quiescent current if battery life is a critical constraint. Verify that the operating temperature range of -25°C to +85°C aligns with the application environment.

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

This regulator belongs to the BDxxGA3WEFJ series, which offers various fixed output voltages ranging from 1.5 V to 12 V. All members share the same HTSOP-J8 package and feature set, differing primarily in their nominal output voltage. The series is designed for standard-grade applications and is not recommended for automotive use.

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

Other variants within the BDxxGA3WEFJ-E2 family, such as BD18GA3WEFJ-E2 or BD33GA3WEFJ-E2, offer different fixed output voltages but share identical pinouts and protective features. Direct substitution requires verifying that the target system voltage matches the new regulator's output specification.
