BD10KA5WFP-E2

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

The BD10KA5WFP-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 1 V output with a maximum load 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, with a maximum of 200 mV. It offers high ripple rejection of 50 dB and maintains a voltage regulation accuracy of 1%. Designed for surface-mount applications, it utilizes a TO-252-5 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 complete part number including the suffix E2 for lead-free compliance. Confirm the specific package variant matches the design requirements. Check the manufacturer's latest datasheet for any updates on electrical characteristics or recommended external components. Ensure the ordering information aligns with the required packaging format.

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

Select this component for designs requiring a precise 1 V rail with moderate current demands. The TO-252-5 package offers thermal advantages over smaller footprints. Consider the 2.3 V minimum input voltage when designing battery-powered systems. The integrated protections simplify board layout by reducing the need for external safety circuits.

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

This regulator belongs to the BD10KA5 series of secondary LDO regulators designed for small size and energy saving. The series includes various fixed output voltages and packages. These regulators are intended for general-purpose applications rather than automotive use. They provide stable performance in compact power management solutions.

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

Check for BD10KA5WF-E2 if SOP-8 packaging is preferred. Verify BD10KA5FP-E2 for TO-252-3 package compatibility. Ensure substitute parts maintain the same 1 V output and 500 mA current rating.
