Description
The TLF80511 is a linear low dropout voltage regulator for load currents up to 400 mA. 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.

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 6 must be maintained. For details
see the typical performance graph “Stability Region: Equivalent Serial Resistor ESR versus Output Current
IQ” on Page 12. 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.
