TLE4275-Q1 5-V LOW-DROPOUT VOLTAGE REGULATOR www.ti.com SLVS647 – AUGUST 2006 FEATURES • • • • • • • • • KTT PACKAGE (TOP VIEW) Qualified for Automotive Applications Output Voltage 5 V ± 2% Very Low Current Consumption Power-On and Undervoltage Reset Reset Low-Level Output Voltage < 1 V Very Low Dropout Voltage Short-Circuit Proof Reverse-Polarity Proof ESD Protection > 6 kV 5 4 3 2 1 OUT DELAY GND RESET IN 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 Ω, 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 Ω, 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 ORDERING INFORMATION PACKAGE (1) TJ –40°C to 150°C (1) TO-263 – KTT Reel of 500 ORDERABLE PART NUMBER TLE4275QKTTRQ1 TOP-SIDE MARKING TLE4275Q1 Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage values are with respect to the network ground terminal. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. The package thermal impedance is calculated in accordance with JESD 51-7.
