Functional Description

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

mA. 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

mA. To achieve proper operation

of the

m-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.
