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

Verify the specific ordering suffix T1-FE corresponds to the SOT-89-5 package and reel quantity of 1,000 pieces per manufacturer specifications. Confirm that the B designation indicates the fixed output voltage type with 3.0 V setting. Ensure compliance with RoHS and halogen-free requirements as stated in the selection guide before finalizing procurement orders.

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

Select this component when a fixed 3.0 V rail is required with high input voltage tolerance up to 24 V. The SOT-89-5 package provides higher power dissipation capabilities compared to smaller footprints. Consider the internal resistance network for fixed voltage applications to minimize external component count and design complexity.

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

This part belongs to the R1155x series of high-voltage LDO regulators manufactured by Nisshinbo Micro Devices. The series offers both fixed and adjustable output variants. The H-series designation specifically denotes the SOT-89-5 package option, distinguishing it from the N-series which utilizes the SOT-23-5 package.
