An input voltage up to 45 V is regulated to VQ,nom = 5.0 V. The IC is able to drive loads up to 450 mA and is short-circuit proof. At overtemperature the TLE 4275 is turned off by the incorporated temperature protection. A reset signal is generated for an output voltage VQ,rt of typ. 4.65 V. The delay time can be programmed by the external delay capacitor.

Using a resistor of approx. 1 Ω 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 µF and an ESR of ≤ 5 Ω 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 incorporates a number of internal circuits for protection against: • • • Overload Overtemperature Reverse polarity Data Sheet 2 Rev. 1.7, 2007-02-19 TLE 4275 PG-TO252-5-11 GND PG-TO220-5-11 1 PG-TO220-5-12 5 Ι RO D Q AEP02580 PG-TO263-5-1 Ι GND Q RO D IEP02527 Ι GND Q RO D AEP02756 Ι GND Q D RO IEP02528 Figure 1 Pin Configuration (top view) Table 1 Pin Definitions and Functions Pin No. Symbol Function 1 I Input; block to ground directly at the IC by a ceramic capacitor. 2 RO Reset Output; open collector output 3 GND Ground; Pin 3 internally connected to heatsink 4 D Reset Delay; connect capacitor to GND for setting delay time 5 Q Output; block to ground with a ≥ 22 µF capacitor, ESR < 5 Ω at 10 kHz.
