Infineon Technologies TLF80511EJ/TC LDO Linear Fixed Voltage Regulators
Infineon TLF80511EJ/TC LDO Linear Fixed Voltage Regulators are a linear low dropout voltage regulator for load currents up to 400mA. The TLF80511EJ/TC with a typical quiescent current of 38μA, is the ideal solution for systems requiring very low operating currents, such as those permanently connected to a battery.
They feature a very low dropout voltage of 100mV, when the output current is less than 100mA. In addition, the dropout region begins at input voltages of 3.3V. This makes the TLF80511EJ suitable to supply automotive systems. In addition, the TLF80511's new fast regulation concept requires only a single, 1μF output capacitor to maintain stable regulation. It is designed for the harsh environment of automotive applications. Therefore standard features like output current limitation and overtemperature shutdown are implemented. They protect the device against failures like output short circuit to GND, over-current and over-temperatures.
