TLE42344G Low Dropout Linear Voltage Regulator Data Sheet Rev. 1.0, 2010-02-08 Automotive Power Low Dropout Linear Voltage Regulator 1 TLE42344G Overview Features • • • • • • • • • • Output voltage tolerance ≤ ±2% Low dropout voltage Output current up to 100 mA Very low current consumption Overtemperature shutdown Output current limitation Suitable for use in automotive electronics Reverse polarity protection Green Product (RoHS compliant) AEC Qualified PG-SOT223-4 Functional Description TLE42344G is a 5 V low dropout fixed voltage regulator in an PG-SOT223-4 package. The IC regulates an input voltage VI in the range 5.5 V < VI < 45 V to VQrated = 5.0 V. The maximum output current is more than 100 mA. This IC is protected against shortcircuit and overheat by the integrated output current limitation and the overtemperature shutdown Dimensioning Information on External Components The input capacitor Ci is necessary for compensating line influences. The output capacitor CQ is necessary for the stability of the regulating circuit. Stability is guaranteed at values CQ ≥ 10 µF and an ESR ≤ 10 Ω within the operating temperature range. Circuit Description The control amplifier compares a reference voltage, which is kept highly precise by resistance adjustment, to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control, working as a function of load current, prevents any over-saturation of the power element.
