The IC regulates an input voltage up P-TO263-3-1 to 40 V to VQrated = 5.0 V (V50), 8.5 V (V85) and 10 V (V10). The maximum output current is 400 mA. The IC is short-circuit proof and incorporates temperature protection that disables the IC at over temperature. A 3.3 V and 2.5 V version is also available. For information about the low output voltage types please refer to the data sheet TLE 4274 / 3.3 V; 2.5 V. Data Sheet Version 1.3 1 2000-10-10 TLE 4274 Dimensioning Information on External Components The input capacitor CI is necessary for compensating line influences. Using a resistor of approx. 1 in series with CI, the oscillating of input inductivity and input capacitance can be damped. The output capacitor CQ is necessary for the stability of the regulation circuit. Stability is guaranteed at values CQ 22 F and an ESR of 3 within the operating temperature range. Circuit Description The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control as a function of the load current prevents any oversaturation of the power element. The IC also includes a number of internal circuits for protection against: * Overload * Overtemperature * Reverse polarity Data Sheet Version 1.3 2 2000-10-10 TLE 4274 P-TO220-3-1 P-TO252-3-1 P-TO263-3-1 GND Q AEP02512 GND Q AEP02281 GND Q AEP01957 Figure 1 Pin Configuration (top view) Pin Definitions and Functions Pin No. Symbol Function 1 I Input; block to ground directly at the IC with a ceramic capacitor. 2 GND Ground 3 Q Output; block to ground with a 22 F capacitor, ESR 3 .
