BH12PB1WHFV-TR

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

The BH12PB1WHFV-TR is a fixed-output CMOS Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 1.2 V output with a maximum continuous current of 150 mA. The device operates within an input voltage range of 1.7 V to 5.5 V and features a typical dropout voltage of 315 mV at full load, with a maximum of 600 mV. Key electrical specifications include a power supply rejection ratio (PSRR) of 60 dB at 1 kHz, line regulation of 2 mV, and load regulation of 10 mV. The quiescent current is typically 4 µA, rising to a maximum of 40 µA. It includes built-in protection circuits for overcurrent, thermal shutdown, and soft start. The component is housed in a compact HVSOF-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 component status before procurement, as this part is designated as Not Recommended for New Designs (NRND). Confirm that existing inventory or last-time buy options align with long-term production requirements. Ensure compatibility with the HVSOF-5 footprint during final assembly planning. Check for RoHS compliance documentation if required by specific regional regulations.

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

Select this regulator when a fixed 1.2 V rail is required with moderate current demands up to 150 mA. Consider the HVSOF-5 package constraints for PCB layout. Evaluate the 60 dB PSRR against noise sensitivity requirements. Verify that the input voltage remains above the minimum threshold of 1.7 V under all operating conditions to maintain regulation.

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

This component belongs to ROHM's series of single-channel CMOS LDO regulators designed for general-purpose power management. It shares the HVSOF-5 form factor with other variants in the family, differing primarily in output voltage and specific protection features. The NRND status indicates it is being phased out in favor of newer generations, though it remains supported for existing designs.
