TPS7B7701QPWPRQ1：Low dropout voltage regulator Automotive 300-mA, off-battery (40-V), adjustable antenna low-dropout voltage regulator 16-HTSSOP -40 to 125The TPS7B770x-Q1 family of devices feature a single- or dual-channel, high voltage LDO with a current-sense function.
These devices operate with a wide input-voltage range of 4.5 V to 40 V (45-V load dump protection). These devices also offers protection of antenna lines against electrostatic discharge (ESD) and from short-toground, short-to-battery, and thermal overstress. Device output voltage is adjustable from 1.5 V to 20 V through an external resistor divider. Alternatively, each channel can be configured as a switch.
These devices provide diagnostics through the current sense and error pins. To monitor the load current, a high-side current-sense circuitry provides a proportional analog output to the sensed load current. The accurate current sense allows detection of open, normal, and short-circuit conditions without the need for further calibration.
