Functional Description
TLE 4261-2 is a high accuracy 5-V low-drop voltage regulator in a P-TO220-7 or in a P-
DSO package. The maximum input voltage is 42 V (65 V/≤ 400 ms). The device can
produce an output current of more than 500 mA. It is short-circuit-proof and incorporates
temperature protection that disables the circuit at impermissibly high temperatures.
