BD15IC0WHFV-GTR

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

The BD15IC0WHFV-GTR is a positive fixed low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 1.5 V output with a maximum continuous current of 1.0 A. The device operates within an input voltage range of 2.4 V to 5.5 V and features a typical dropout voltage of 400 mV at full load. Output accuracy is maintained at ±1% under standard conditions. It includes built-in overcurrent protection, thermal shutdown, and a shutdown function that reduces standby current to 0 µA. The component is housed in an HVSOF-6 surface-mount package and supports operation temperatures from -25°C to +85°C.

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

Verify the specific suffix GTR indicates tape-and-reel packaging when ordering. Confirm the HVSOF-6 footprint matches your PCB layout constraints. Ensure input voltage does not exceed 7 V maximum rating. Check RoHS compliance status if required for your manufacturing process. Validate operating temperature range suitability for your final assembly environment.

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

Select this component when a fixed 1.5 V output is required rather than adjustable variants like the BD00IC series. Choose this LDO for applications prioritizing low quiescent current and compact HVSOF-6 packaging over higher current capabilities. Consider the 400 mV dropout voltage against your minimum input voltage headroom requirements. Opt for this part if integrated thermal and overcurrent protection are critical for system safety without external components.

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

This regulator belongs to the BDxxIC0W series from ROHM, designed for 1.0 A output applications. The series offers both fixed and adjustable output options, allowing designers flexibility in voltage selection. The BD15IC variant specifically targets the 1.5 V market segment, common in modern digital logic families. The family emphasizes small form factors and high reliability through internal protection mechanisms.

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

Direct substitutes may include other ROHM LDOs in the same HVSOF-6 package with compatible 1.5 V outputs. Verify pin compatibility and electrical specifications before swapping. Adjustable versions require external resistors and do not offer direct pin-to-pin replacement for fixed voltage needs.
