5 3 The TLE4276 is a low-drop voltage regulator in a TO package. The IC regulates an input voltage up to 4 V to V Q,nom = 5. V (V5), and adjustable voltage (V). The maximum output current is 4 ma. The IC can be switched off via the inhibit input, which causes the current consumption to drop below µa. The IC is short-circuitproof and includes temperature protection which turns off the device at overtemperature. Dimensioning Information on External Components The input capacitor C I is necessary for compensation of line influences. Using a resistor of approx. Ω in series with C I, the oscillating of input inductivity and input capacitance can be damped. The output capacitor C Q is necessary for the stability of the regulation circuit. Stability is guaranteed at values C Q 22 μf and an ESR of 3 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 5 Rev. 2.8

10 Application Information for Variable Output Regulator TLE 4276 V The output voltage of the TLE 4276 V can be adjusted between 2.5 V and 2 V by an external output voltage divider, closing the control loop to the voltage adjust pin VA. The voltage at pin VA is compared to the internal reference of typical 2.5 V in an error amplifier. It controls the output voltage. 5 Q Internal Reference 2.5 V Typical V ref Current and Saturation Control R C Q 22 µf 4 VA R 2 AEB284 Figure 5 Application Detail External Components at Output for Variable Voltage Regulator The output voltage is calculated according to Equation (3.): V Q = (R + R 2 )/R 2 V ref, neglecting I VA (3.) V ref is typically 2.5 V. To avoid errors caused by leakage current I VA, we recommend to choose the resistor value R 2 according to Equation (3.2): R 2 < 5 kω For a 2.5 V output voltage the output pin Q is directly connected to the adjust pin VA. The accuracy of the resistors R and R 2 add an additional error to the output voltage tolerance. The operation range of the variable TLE 4276 V is V Q +.5 V to 4 V. For internal biasing a minimum input voltage of 4.3 V is required. For output voltages below 4 V the voltage drop is 4.3 V - V Q (3.2) Data Sheet Rev. 2.8
