BD12IC0WHFV-GTR

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

The BD12IC0WHFV-GTR is a fixed-output low dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable positive output voltage of 1.2 V with a maximum continuous output current of 1.0 A. The device operates within an input voltage range up to a maximum of 7 V and maintains performance across a junction temperature range from -25 °C to +85 °C. Key electrical specifications include a typical dropout voltage of 400 mV at full load, a quiescent supply current of 250 µA, and a load regulation of 1.5 %. It utilizes a 6-pin HVSOF surface-mount package.

• Fixed 1.2 V output voltage configuration for precise power rail generation
• Integrated overcurrent protection and thermal shutdown circuits for device safety
• Low quiescent current consumption to support energy-efficient system designs
• Capable of delivering 1.0 A output current with minimal voltage drop

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

• Portable electronic devices requiring stable low-voltage power supplies
• Battery-operated equipment needing efficient linear regulation
• Digital logic circuits powered by 1.2 V rails
• Embedded systems utilizing surface-mount assembly processes

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

Verify the complete part number including the suffix GTR to confirm tape-and-reel packaging format. Ensure compatibility with the target PCB footprint for the 6-HVSOF package. Confirm that the required output voltage matches the fixed 1.2 V specification, as this variant does not offer adjustable output. Check RoHS compliance status if restricted substances are a constraint for the final assembly.

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

Select this component when a fixed 1.2 V output is required rather than an adjustable topology. It is suitable for applications where input voltages do not exceed 7 V and output currents reach up to 1.0 A. Consider the thermal dissipation capabilities of the HVSOF package relative to the ambient operating conditions. Compare against other LDOs in the series if different output voltages or higher current ratings are needed.

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

This regulator belongs to ROHM's standard LDO series designed for general-purpose power management. The BD12IC0WHFV-GTR specifically addresses the need for compact, low-cost voltage regulation in consumer electronics. It shares functional similarities with other members of the BDxxIC0 family, differing primarily in the fixed output voltage setting and specific package variations available within the product line.

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

Direct substitutes may include other ROHM LDOs with identical 1.2 V output and 1.0 A rating, such as variants in different packages like HTSOP-J8 if pinout compatibility allows. Cross-manufacturer replacements must match the 1.2 V fixed output, 1.0 A current capacity, and 7 V maximum input voltage constraints.
