BD3550HFN Ultra Low Dropout Linear Regulators

BD3550HFN,BD3551HFN,BD3552HFN ultra low-dropout linear chipset regulator operates from a very low input supply, and offers ideal performance in low input voltage to low output voltage applications. It incorporates a built-in N-MOSFET power transistor to minimize the input-to-output voltage different.

BD3550HFN Features
