SLVS647H –AUGUST 2006–REVISED MARCH 2013

5-V LOW-DROPOUT VOLTAGE REGULATOR

Check for Samples: TLE4275-Q1

FEATURES

• Qualified for Automotive Applications • Reset Low-Level Output Voltage < 1 V

• Output Voltage 5 V ± 2% • Very Low Dropout Voltage

• Very Low Current Consumption • Short-Circuit Proof

• Power-On and Undervoltage Reset • Reverse-Polarity Proof

DESCRIPTION

The TLE4275 is a monolithic integrated low-dropout voltage regulator offered in a 5-pin TO package. The device

regulates an input voltage up to 45 V to V

OUT

= 5 V (typ). The device can drive loads up to 450 mA and is short-

circuit proof. At overtemperature, the incorporated temperature protection turns off the TLE4275. The device

generates a reset signal for an output voltage, V

OUT,rt

, of 4.65 V (typ). By the use of an external delay capacitor,

one can program the reset delay time.

The input capacitor, C

, compensates for line fluctuation. Using a resistor of approximately 1 Ω in series with C

dampens the oscillation of input inductance and input capacitance. The output capacitor, C

OUT

, stabilizes the

regulation circuit. The specification for stability is at C

OUT

≥ 22 μF and ESR ≤ 5 Ω, within the operating

temperature range. Stability for electrolytic capacitors specifically is at C

OUT

≥ 68 µF within the operating

temperature range. See the application report on low-temperature stability, SLVA501, for further details.

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
