TLF80511TC

The TLF80511TC is a linear low dropout voltage regulator for load currents up to 400 mA in D2PAK,  DPAK and DSO8-EP packages with fixed output voltage (5V and 3.3V). An input voltage of up to 40 V is regulated to V _Q,nom  = 5 V with ±2 % precision. The  TLF80511TC  with  a  typical  quiescent  current  of  38 μA,  is  the  ideal  solution  for  systems  requiring  very  low operating currents, such as those permanently connected to a battery. It features a very low dropout voltage of 100 mV, when the output current is less than 100 mA. In addition, the dropout region begins at input voltages of 3.3 V (extended operating range). This makes the TLF80511 suitable to supply automotive systems. In addition, the TLF80511TC’s new fast regulation concept requires only a single, 1 μF output capacitor to maintain stable regulation.
