BH1JLB1WHFV-TR

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

The BH1JLB1WHFV-TR is a single-output fixed linear voltage regulator manufactured by ROHM Semiconductor. It provides a stable 1.85 V output with a maximum load current of 150 mA. The device operates within an input voltage range up to 5.5 V and features a typical dropout voltage of 250 mV at 100 mA. It includes comprehensive protection mechanisms such as thermal shutdown, overcurrent protection, and a shutdown function. The component is housed in a compact HVSOF-5 package and is rated for operation between -40°C and +85°C.

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

Verify the NRND (Not Recommended for New Designs) status before procurement, as this indicates the component is likely being phased out. Confirm availability through authorized distributors only, as stock levels may be limited or discontinued. Ensure the HVSOF-5 package footprint matches your PCB design constraints. Request updated lifecycle documentation from the manufacturer to assess long-term support viability.

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

Select this regulator when a precise 1.85 V rail is required with minimal external components. The low dropout characteristic makes it suitable for applications where the input voltage is close to the output level. Consider the 150 mA current limit against your peak load requirements. The integrated shutdown feature allows for system-wide power saving modes. Verify that the thermal performance in your specific enclosure meets the junction temperature limits under full load conditions.

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

This component belongs to ROHM's standard CMOS LDO regulator series, designed for general-purpose power management in consumer and industrial electronics. The BH1JLB1WHFV-TR variant specifically targets applications requiring a 1.85 V output. It shares common protection features with other members of the family but differs in output voltage and specific package options. The series emphasizes stability and ease of use with minimal external capacitance requirements.

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

Public confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, direct replacements should be sourced from ROHM's current portfolio. Evaluate alternative LDOs with similar 1.85 V output, 150 mA capability, and HVSOF-5 packaging. Ensure any substitute maintains compatible pinout and protection features to minimize redesign efforts.
