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

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. Therefore it is protected against overload, short

circuit and overtemperature.
