Description TLE7270-2 monolithic integrated dropout voltage regulator load currents input voltage regulated VQ,nom with precision ±2%. integrated reset circuitry featuring power timing output voltage monitoring well suited µ-controller supply. sophisticated design allows achieve stable operation even with ceramic output capacitors down device designed harsh environment automotive applications. Therefore protected against overload, short circuit overtemperature conditions implemented output current limitation overtemperature shutdown circuit. TLE7270-2 also used other applications requiring stabilized voltage. ultra quiescent current typically TLE7270-2 dedicated applications permanently connected VBAT. integrated output sink current circuitry keeps voltage Output below even case occuring reverse currents. Thus connected devices protected from overvoltage damage. applications requiring extremely noise levels Infineon voltage regulator family 42XX 44XX more suited than TLE7270-2. mVrange output noise TLE7270-2 caused charge pump operation unavoidable ultra quiescent current concept.

Electrical Characteristics Reset Function
Reset function informs e.g. microcontroller case output voltage fallen below lower threshold typ. 4.65 headroom between output voltage reset threshold typically Connecting regulator battery voltage first reset signal remains LOW. When output voltage reached reset threshold reset output remains still reset delay time tRD. Afterwards reset output turns HIGH.
