BH30MA3WHFV-TR

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

The BH30MA3WHFV-TR is a CMOS LDO voltage regulator from ROHM Semiconductor, providing a fixed 3.0 V output with a maximum load current of 300 mA. It operates within an input voltage range of 2.5 V to 5.5 V and features a typical dropout voltage of 60 mV at full load. The device offers a power supply rejection ratio (PSRR) of 60 dB and supports surface mount installation in a compact HVSOF-6 package. It functions reliably across an operating temperature range of -40°C to +85°C.

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

Verify the NRND status before procurement, as this component is not recommended for new designs. Confirm that the HVSOF-6 package matches your PCB footprint requirements. Ensure input voltage does not exceed 5.5 V to prevent damage. Check datasheet specifications for thermal dissipation limits under expected load conditions. Validate compatibility with existing system architecture due to end-of-life implications.

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

Select this regulator when a fixed 3.0 V output is required with moderate current capability up to 300 mA. Consider its narrow input voltage window (2.5 V–5.5 V) for applications where supply variation is minimal. Evaluate thermal performance in enclosed spaces due to 680 mW power dissipation rating. Compare against newer ROHM LDOs if long-term availability is critical for the product lifecycle.
