The TPS3103K33DBVT is a precision voltage supervisor designed for monitoring supply voltages in low-power applications. It operates within a supply voltage range of 0.9 V to 3.6 V and features a high trip-point accuracy of 0.75%. The device has a typical supply current of 1.2 OºA, making it suitable for battery-powered and portable equipment. It asserts a reset signal low when the supply voltage exceeds 0.4 V and includes a power-on reset generator with a delay time of 130 ms. The output can be configured as either push-pull or open-drain. The TPS3103K33DBVT is housed in a compact SOT-23 package and is rated for operation over a temperature range of -40¬8C to 125¬8C, making it suitable for a variety of industrial and consumer applications.
