BH30FB1WG-TR

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

The BH30FB1WG-TR is a single-channel, fixed-output CMOS Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3.1V output with a maximum current capacity of 150mA. The device operates within an input voltage range of 2.5V to 5.5V and features a typical dropout voltage of 0.25V at 100mA load. Key electrical specifications include a line regulation of 20mV, load regulation of 10mV, and a ripple rejection ratio of 80dB. The unit is housed in an HVSOF-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

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

This component carries a status of Not Recommended for New Designs (NRND). Manufacturers typically continue production only to support existing customers. Procurement should verify current availability through authorized distributors, as supply may be limited or subject to last-time-buy constraints. Ensure compatibility with legacy designs before initiating orders.

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

Engineers selecting this part must account for its NRND status, which indicates it is not intended for new product development. Verify that the 3.1V fixed output and 150mA current limit meet system requirements. Consider alternative components if long-term supply assurance is critical for future production runs.

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

The BH30FB1WG-TR belongs to ROHM's series of standard CMOS LDO regulators designed for low-power applications. It shares functional similarities with other parts in the family but is distinguished by its specific 3.1V output voltage and HVSOF-5 packaging. This component serves as a power management solution for circuits requiring efficient voltage regulation from lithium-ion or similar battery sources.

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

The BH30NB1WHFV is documented as a substitute part number with similar specifications. Both are marked as Not Recommended for New Designs. Verify pinout compatibility and parameter alignment before substitution.
