The RT7251BZQW is a voltage regulator designed for DC/DC switching applications. It is a Monolithic Three-terminal Positive Regulator with onboard overvoltage protection (OVP) and overcurrent protection (OCP). It is designed to provide high efficiency and reliability while operating in the power range of 0.1W to 5W. The RT7251BZQW is housed in an SOT-89-5 package, making it ideal for space-constrained applications. The device is rated for an input voltage range of 2.6V to 25V, and has an output voltage range of 0.9V to 6V.

The RT7251BZQW accepts an input voltage range between 2.6V to 25V through its VIN pin and provides regulated output voltages ranging from 0.9V to 6V via its VOUT pin. It also features low shutdown current, high output accuracy, adjustable output voltage and low output noise. Additionally, the device offers an interlock with output OVP, safety protection features and both cycle-by-cycle and hiccup mode current limit protections.

The RT7251BZQW features on-board switching frequency. The switching frequency can be adjusted by an internal resistor. An external compensation capacitor can be used to optimize the dynamic response of the regulator and to compensate for line and load variation. The device also includes a soft-start circuit which sets the regulator into a predefined output voltage in a gradual manner. This reduces the inrush current at the start of the regulator operation.

The RT7251BZQW can be used in a variety of applications including step-up/down converters, battery charging circuits, automotive systems, consumer electronics and mobile phones. The device is well suited for applications where low noise and high efficiency energy conversion is necessary.
