| Low Drop Voltage Regulator TLE 4296 Features * * * * * * * * * * * * Three versions: 3.0 V, 3.3 V, 5.0 V Output voltage tolerance 4% Very low drop voltage Output current: 30 mA Inhibit input Low quiescent current consumption Wide operation range: up to 45 V Wide temperature range: -40 C Tj 150 C Output protected against short circuit Overtemperature protection Reverse polarity proof Very small SMD-Package P-SCT595-5 SCT 595 Functional Description The TLE 4296 G is a monolithic integrated low drop voltage regulator in the very small SMD package P-SCT595-5. It is designed to supply e.g. microprocessor systems under the severe conditions of automotive applications. Therefore the device is equipped with additional protection functions against overload, short circuit and reverse polarity. At overtemperature the regulator is automatically turned off by the integrated thermal protection circuit. Input voltages up to 40 V are regulated to VQ,nom = 3.0 V (V30 version) 3.3 V (V33 version) or 5.0 V (V50 version). The output is able to drive a load of more than 30 mA while it regulates the output voltage within a 4% accuracy. To save energy the device can be switched in stand-by mode via an inhibit input which causes the current consumption to drop below 5 A.

The regulation loop controls the output to achieve a stabilized output voltage. Figure 3 shows a typical application circuit. In order to maintain the stability of the control loop the TLE 4296 G output requires an output capacitor CQ of at least 2.2 F with an ESR of max. 10 and min. 3 . It is recommended to use tantalum (e.g. the EPCOS 3.3 F / 16V B45196P3335M209 or 4.7 F / 10 V B45196-P2475M109) or a multi layer ceramic capacitor with a series resistor in order to cover these limits over the full operating temperature range of -40 C to 150 C. At the input of the regulator an input capacitor is necessary for compensating line influences (100 nF ceramic capacitor recommended). A resistor of approx. 1 in series with CI, can damp any oscillation occurring due the input inductivity and the input capacitor.
