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. Semiconductor Group 1 1998-11-01 TLE 4261-2 Application Description The IC regulates an input voltage VI in the range 6 V < VI < 40 V to VQrated = 5.0 V. A reset signal is generated for an output voltage VO of < 4.75 V. The reset delay can be set with an external capacitor. A connected microprocessor is monitored by the integrated watchdog circuit; if pulses are missing, the reset output is set low. The ...
