This data sheet provides detailed information on the 5V low-drop voltage regulator TLE 4263, including features, type, package, functional description, external component information, etc.

TLE 4264 G is a 5 V low drop fixed-voltage regulator in an SOT-223 package. The IC regulates an input voltage VI in the range 5.5 V < VI < 45 V to VQrated = 5.0 V. The maximum output current is more than 120 mA. This IC is shortcircuit-proof and features temperature protection that disables the circuit at overtemperature.

TLE 6252 G is a fault tolerant differential CAN transceiver optimized for low-speed data transmission (up to 125 kBaud) in automotive and industrial applications. The device supports 125 kBaud data transmission, and automatically switches to single-wire mode to maintain communication when bus wiring failures are detected. While no data is transferred, the power consumption can be minimized by multiple low power modes.
