The BD3550HFN, BD3551HFN, and BD3552HFN are a series of high-performance regulator ICs designed for PCs. They feature ultra-low dropout and linear regulation, making them ideal for low input voltage to low output voltage applications. These ICs incorporate a built-in N-MOSFET power transistor to minimize the voltage differential and achieve high current output with reduced conversion loss. This eliminates the need for a switching regulator and its components, resulting in package profile downsizing and cost reduction.

BD3540NUV, BD3541NUV are low voltage output linear 1ch series chipset regulator ICs that operate from a very low input supply, and offer 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 differential to the ON resistance (RON=200mΩ～ 400mΩ) level. By lowering the dropout voltage in this way, the regulator realizes high current output (Iomax=0.5A～1.0A) with reduced conversion loss, and thereby obviates the switching regulator and its power transistor, choke coil, and rectifier diode. Thus, the BD3540NUV, BD3541NUV are designed to enable significant package profile downsizing and cost reduction. An external resistor allows the entire range of output voltage configurations between 0.65 and 2.7V, while the NRCS (soft start) function enables a controlled output voltage ramp-up, which can be programmed to whatever power supply sequence is required.
