User Manual
The TLE 4299 is a low-drop fixed voltage regulator with an output voltage of 3.3V ± 2%, an output current of 150 mA, extreme low current consumption in ON state, below 1µA current consumption in off mode, early warning function, reset output low down to VQ = 1 V, overtemperature protection, reverse polarity proof, and wide temperature range.
Datasheet
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.
