BD10KA5WF-E2

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

The BD10KA5WF-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 1 V output with a maximum continuous current of 500 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 120 mV at 0.2 A load. It offers high ripple rejection of 50 dB and maintains a voltage regulation accuracy of ±1%. The component supports surface-mount installation in an SOP-8 package and functions reliably across an extended temperature range from -40°C to +105°C.

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

• Integrated ON/OFF switch enables zero current consumption during shutdown mode
• Built-in overcurrent protection safeguards against output short circuits
• Thermal shutdown circuit prevents damage under overload conditions

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

• Local power supply circuits for consumer electronics
• Power management in automotive audio systems
• Voltage regulation for hard disk drives and PC peripherals
• Power stages for DVD players and similar devices

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

Verify the specific suffix E2 to confirm compliance with RoHS directives and REACH standards before integration. Confirm the SOP-8 package variant matches your PCB footprint requirements. Ensure the fixed 1 V output aligns with target load specifications, as adjustable variants exist within the same series. Validate thermal dissipation capabilities relative to ambient operating temperatures up to 105°C.

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

Select this component when a precise 1 V rail is required with minimal voltage drop. The SOP-8 package suits applications needing multiple channels or higher pin counts compared to smaller footprints. Consider the 500 mA limit for load demands; higher current needs require alternative series. The wide input range accommodates single-cell battery systems or standard 3.3 V/5 V rails.

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

This part belongs to the BD10KA5WF series of secondary LDO regulators designed for miniaturization and energy efficiency. The series includes various fixed output voltages and packages. Unlike automotive-grade counterparts such as the BD4XS5-C, this standard-grade product is explicitly not recommended for use in车载 equipment despite its robust protection features.

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

Direct substitutes include other fixed-output variants within the BD10KA5WF family, such as BD25KA5WF-E2 for 2.5 V or BD33KA5WF-E2 for 3.3 V outputs, provided the SOP-8 package and 500 mA rating remain compatible.
