BH25NB1WHFV-TR Application Field and Working Principle

BH25NB1WHFV-TR is a linear voltage regulator IC from Toshiba, designed to help providing stable, accurate power regulation as well as maximum efficiency in a variety of applications. The device provides specified regulation over a wide range of load and line changes, and is capable of delivering up to 2.5A of output current.

Fields of Application

The BH25NB1WHFV-TR is suitable for a wide range of applications, including but not limited to, systems that require a precise reference level, like digital systems that use logic families such as TTL, ECL, CMOS and LVTTL; audio equipment; camera modules; TV and VCRs; medical devices; instrumentation and control systems; communications equipment and telecommunications systems.

Features and Benefits

The BH25NB1WHFV-TR is widely known for its precise regulation over changing temperatures and wide range of line and load changes. It offers low voltage dropout and current consumption, which allows a minimum number of external components and energy savings. The heat dissipation from its packages is kept low thanks to its low current consumption and SOP package. An output voltage fault protection circuit and adjustable voltage setting capability are also available for added convenience.

Working Principle

The BH25NB1WHFV-TR adopts a two stage, series voltage regulator circuit, which consists of a switching element and a controlling element. The switching element, which is the regulator\'s power section, works to reduce the output voltage of the converter to the desired level. The regulating element, on the other hand, maintains the output voltage at a certain level, with the input voltage varying or with variations in the circuit\'s load conditions. The output voltage is handled by a feedback loop connecting the regulator\'s output to its input. Adjustments to the output voltage can be made by altering the current flowing through the feedback loop, which alters the control voltage at the regulator\'s control terminal.

Conclusion

The BH25NB1WHFV-TR from Toshiba is an efficient and precise linear voltage regulator IC that is suitable for a broad range of applications, including digital systems, audio equipment, camera modules, TV and VCRs, medical devices, instrumentation and control systems, communications equipment, and telecommunications systems. With its two-stage series voltage regulator circuit and adjustable voltage setting capability, it is ideal for applications requiring precise regulation over changing temperatures and wide range of line and load changes. The device also offers low voltage dropout, low current consumption, and low heat dissipation.
