DESCRIPTION/ORDERING INFORMATION

The TLE4275 is a monolithic integrated low-dropout voltage regulator offered in a 5-pin TO package. An input voltage up to 45 V is regulated to VOUT = 5 V (typ). The device can drive loads up to 450 mA and is short-circuit proof. At overtemperature, the TLE4275 is turned off by the incorporated temperature protection. A reset signal is generated for an output voltage, VOUT,rt, of 4.65 V (typ). The reset delay time can be programmed by the external delay capacitor.

The input capacitor, CIN, compensates for line fluctuation. Using a resistor of approximately
1 , in series with CIN, dampens the oscillation of input inductivity and input capacitance. The output capacitor, COUT, stabilizes the regulation circuit. Stability is specified at COUT ≥ 22 µF and ESR ≤ 5 , within the operating temperature range.

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 device also incorporates a number of internal circuits for protection against:

  • Overload
  • Overtemperature
  • Reverse polarity
