The IC regulates an input voltage up to 40 V to VQ,nom = 5.0 V (V50), and adjustable voltage (V). The maximum output current is 400 mA. The IC can be switched off via the inhibit input, which causes the current consumption to drop below 10 µA. The IC is short-circuit-proof and includes temperature protection which turns off the device at overtemperature. Dimensioning information on external components The input capacitor CI is necessary for compensation of line influences. 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. The stability is guaranteed at values CQ ≥ 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 Datasheet 5 Rev. 2.90 2023-06-28 OPTIREG™ linear TLE4276 Low drop voltage regulator Functional description Table 2 Absolute maximum ratings Parameter Symbol Limit Values Min.

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 Current and Saturation Control Vref R1 CQ 22 µF 4 VA R2 AEB02804 Figure 5 Application detail external components at output for variable voltage regulator The output voltage is calculated according to Equation (3.1): VQ = (R1 + R2)/R2 × Vref, neglecting IVA (3.1) Vref is typically 2.5 V. To avoid errors caused by leakage current IVA, we recommend to choose the resistor value R2 according to Equation (3.2): R2 < 50 kΩ (3.2) For a 2.5 V output voltage the output pin Q is directly connected to the adjust pin VA. The accuracy of the resistors R1 and R2 add an additional error to the output voltage tolerance. The operation range of the variable TLE4276V is VQ + 0.5 V to 40 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 - VQ.
