Low Drop Voltage Regulator TLE 4276 Features • • • • • • • • • • • 5 V, 8.
TLE 4276 Functional Description The TLE 4276 is a low-drop voltage regulator in a TO package. The IC regulates an input voltage up to 40 V to VQ,nom = 5.0 V (V50), 8.5 V (V85), 10 V (V10) and adjustable voltage (V). The maximum output current is 400 mA. The IC can be switched off via the inhibit input, which causes the current consumption to drop below 10 µA. The IC is short-circuitproof and includes temperature protection which turns off the device at overtemperature.

TLE 4276 Application Information for Variable Output Regulator TLE 4276 V, SV, DV, GV The output voltage of the TLE 4276 V can be adjusted between 2.5 V and 20 V by an external output voltage divider, closing the control loop to the voltage adjust pin VA. The voltage at pin VA is compared to the internal reference of typical 2.5 V in an error amplifier. It controls the output voltage. 5 Q Internal Reference 2.
