An input voltage of up to 40 V is regulated to VQ,nom = 5 V with ±2 % precision. The TLF80511 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 TLF80511’s new fast regulation concept requires only a single, 1 µF output capacitor to maintain stable regulation. The device is designed for the harsh environment of automotive applications. Therefore standard features like output current limitation and overtemperature shutdown are implemented and protect the device against failures like output short circuit to GND, over-current and over-temperatures. The TLF80511 can be also used in all other applications requiring a stabilized 5 V supply voltage.

Data Sheet 2 Rev. 1.0, 2012-06-15 TLF80511 Block Description and Electrical Characteristics 5 Block Description and Electrical Characteristics 5.1 Voltage Regulation The output voltage VQ is divided by a resistor network. This fractional voltage is compared to an internal voltage reference and drives the pass transistor accordingly. The control loop stability depends on the output capacitor CQ, the load current, the chip temperature and the internal circuit design. To ensure stable operation, the output capacitor’s capacitance and its equivalent series resistor ESR requirements given in Table 4.2 “Functional Range” on Page 2 must be maintained. For details see the typical performance graph “Stability Region: Equivalent Serial Resistor ESR versus Output Current IQ” on Page 6. Since the output capacitor is used to buffer load steps, it should be sized according to the application’s needs. An input capacitor CI is not required for stability, but is recommended to compensate line fluctuations. An additional reverse polarity protection diode and a combination of several capacitors for filtering should be used. Connect the capacitors close to the regulator terminals. Whenever the load current exceeds the specified limit, e.g. in case of a short circuit, the output current is limited and the output voltage decreases. The overtemperature shutdown circuit prevents the IC from immediate destruction under fault conditions (e.g. output continuously short-circuited) by switching off the power stage. After the chip has cooled, the regulator restarts. This oscillatory thermal behaviour causes the junction temperature to exceed the 150° C maximum and significantly reducing the IC’s life.
