BD800M5WFPJ-CE2

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

The BD800M5WFPJ-CE2 is a single-output positive low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It operates within an input voltage range of 3 V to 42 V and delivers a maximum output current of 500 mA. The device features adjustable output voltage settings between 1.2 V and 16 V, with a typical ripple rejection ratio of 70 dB. Key electrical parameters include a quiescent current of 17 uA, an input bias current of 4 uA, and line/load regulation of 0.02%. The unit functions in a TO-252-J5 package across a temperature range of -40 °C to +125 °C.

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

Verify the specific suffix CE2 against the manufacturer's official datasheet to confirm exact packaging and compliance specifications. Ensure the TO-252-J5 package variant matches your PCB footprint requirements. Confirm that the adjustable output version aligns with your circuit design needs rather than fixed-voltage alternatives.

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

Select this component when designing automotive circuits that require high input voltage tolerance up to 42 V. The low quiescent current makes it suitable for battery-powered applications where standby consumption must be minimized. Verify that the required output voltage falls within the 1.2 V to 16 V adjustable range and that the thermal environment supports the specified operating temperature limits.
