BH18LB1WHFV-TR

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

The BH18LB1WHFV-TR is a fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 1.8 V output with a maximum continuous current of 150 mA. The device operates within an input voltage range up to 6.5 V and features a maximum dropout voltage of 450 mV at full load. It includes built-in protection mechanisms such as thermal shutdown and overcurrent protection. The component is housed in a compact HVSOF-EP-5 surface-mount package and is rated for operation between -40 °C and +85 °C.

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

Verify the specific suffix and package variant against the official datasheet, as ordering codes may differ slightly across distributors. Confirm RoHS compliance status directly from the manufacturer's documentation before integration. Check for end-of-life or not-recommended-for-new-designations on the product page to ensure long-term availability for production planning.

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

Select this component when a precise 1.8 V rail is required for low-power digital or RF loads. Ensure the input voltage remains within the specified limits to maintain regulation. Verify that the PCB layout supports the HVSOF-EP-5 footprint and thermal requirements. Compare quiescent current and dropout characteristics against alternative LDOs if battery life or efficiency is critical.

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

This part belongs to ROHM's standard CMOS LDO regulator family, designed for portable electronic applications. It shares architectural similarities with other members like the BH12PB1 and BH15LB1 series, differing primarily in output voltage and specific package options. The family emphasizes low noise and high ripple rejection for sensitive analog and digital circuits.

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

Direct pin-compatible substitutes include the BH15LB1WHFV-TR (1.5 V output) and BH12PB1WHFV-TR (1.2 V output) from the same manufacturer. Cross-brand replacements require verification of pinout compatibility, output voltage tolerance, and thermal performance specifications.
