The TLE 4299 is a monolithic voltage regulator with fixed 5-V output, supplying loads up to 150 mA. It is especially designed for applications that may not be powered down while the motor is off. It only needs a quiescent current of typical 65 µA. In addition the TLE 4299 GM includes an inhibit function. When the inhibit signal is removed, the device is switched off and the quiescent current is less than 1 µA. To achieve proper operation of the µ-controller, the device supplies a reset signal. The reset delay time is selected application-specific by an external delay capacitor. The reset threshold is adjustable. An early warning signal supervises the voltage at pin SI. The TLE 4299 is pin-compatible to the TLE 4269 and functional similar with the additional inhibit function. The TLE 4299 is designed to supply microcontroller systems even under automotive environment conditions.
The TLE4299 is a PNP-based linear voltage regulator designed to supply loads up to 150 mA with an output voltage of 5 V (+/- 2%). It features extreme low current consumption, typically 65 pA in the ON state, and includes an inhibit function for the GM variant that reduces quiescent current below 1 nA when disabled. The device is specifically designed to supply microcontroller systems under automotive environmental conditions.
