BH15MA3WHFV-TR

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

The BH15MA3WHFV-TR is a fixed-output CMOS Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 1.5 V with a maximum output current of 300 mA. The device operates within an input voltage range of 2.5 V to 5.5 V and features a typical dropout voltage of 60 mV at 100 mA load. It includes shutdown functionality, thermal shutdown protection, and overcurrent protection. The regulator offers a typical power supply rejection ratio (PSRR) of 60 dB and maintains a line regulation of 2 mV and load regulation of 18 mV. It is housed in a compact HVSOF-6 surface-mount package.

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

Verify the component status as Not Recommended for New Designs (NRND). Confirm that the specific orderable part number matches the required suffix and packaging format. Ensure compatibility with existing designs rather than initiating new ones due to potential end-of-life constraints.

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

Select this component when a fixed 1.5 V output is required with low quiescent current consumption. Consider the HVSOF-6 package size for space-constrained layouts. Verify that the input voltage remains within the specified 2.5 V to 5.5 V range and that the load current does not exceed 300 mA.
