TLE7469GV52

Product Summary

The TLE7469GV52 is a monolithic integrated voltage regulator with two voltage outputs specially designed to supply microcontrollers with dual supply voltage: 2.6 V1) or 3.3 V core and 5 V I/O voltage like the Infineon XC164 and XC161. The voltage regulator features an integrated reset circuitry which monitors the 2.6 V/ 3.3 V supply voltage. At power on the reset checks both supply voltages and performs the power-on reset with an adjustable delay time. The voltage difference is kept in the range -0.5 V < (VQ1 - VQ2) < 3.0 V even during power-on and power-down time enabling save μC operation without external clamping. Using the integrated early warning comparator an external voltage can be supervised. An integrated output sink current circuitry keeps the voltage at the Q1 pin below 5.5 V even when reverse currents are applied. Thus connected devices are protected from overvoltage damage. The regulator can be shut down via the Inhibit input causing the current consumption to drop below 9 μA.
