XT-ShenZhen always believes that treating customers with sincerity and mutual respect with customers can maintain a long-term cooperative relationship. Le TPS7B7701QPWPRQ1 device is an adjustable antenna low dropout regulator from Texas Instruments. The device features automotive 300mA, battery-powered operation (40V). XT-ShenZhen only provides customers with high-quality products and services, and solves short-term product problems for customers! Please rest assured to buy new and old customers!
The TPS7B7701QPWPRQ1 device is a high-voltage low-dropout regulator (LDO) that uses single- and dual-channel current sensing. It is suitable for a wide input voltage operating range from 4.5V to 40V (45V load dump protection). The device uses a single coaxial cable with 300 mA per channel to power the active antenna’s low-noise amplifier. Each channel provides an adjustable output voltage from 1.5 à 20 V.
The TPS7B7701QPWPRQ1 device uses a reverse-polarity diode and does not require an external diode. The product has short-circuit protection of the output battery, reverse current protection and standard thermal shutdown. Each channel provides internal inductive clamping protection for the output during inductive switch off periods.
