BAJ2DD0WHFP-TR

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

The BAJ2DD0WHFP-TR is a fixed-output low-dropout (LDO) voltage regulator from ROHM Semiconductor, designed for high-current applications with a maximum output current of 2A. It operates within an input voltage range of 3V to 25V and withstands up to 36V. The device features a typical dropout voltage of 0.45V at full load and includes integrated shutdown functionality for power management. Protection mechanisms include over-current, thermal shut-down, and over-voltage protection. It is housed in an HRP-5 surface-mount package and supports an operating temperature range from -40°C to 125°C.

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

Verify the specific fixed output voltage variant required, as the suffix indicates the package and tape/reel format but not the voltage value. Confirm RoHS compliance status for your region. Ensure the HRP-5 footprint matches your PCB layout. Check for end-of-life notices if long-term production stability is critical for your design.

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

Select this component when a 2A output capability with a shutdown feature is necessary. Compare dropout voltage specifications against your minimum input-output differential requirements. Consider the thermal performance in your enclosure design due to the 2A current rating. Verify that the fixed output voltage meets your system's rail requirements without additional adjustment resistors.

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

This part belongs to ROHM's BAxxDD0 series of 2A fixed-output LDO regulators with shutdown switches. It complements other variants in the family that offer different fixed voltages or packages.
