Functional Description

The TLE 4299 is a monolithic voltage regulator with fixed

5-V (see data sheet TLE4299G/GM) or 3.3 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. In addition the TLE 4299GMV 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. Therefore it is protected against overload, short

circuit and over temperature.
