data sheet 2 rev. 2.4, 2004-01-01 tle 4276 functional description the tle 4276 is a low-drop voltage regulator in a to package. the ic regulates an input voltage up to 40 v to v q,nom = 5.0 v (v50), 8.5 v (v85), 10 v (v10) 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 a. 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 c i is necessary for compensation of line influences. using a resistor of approx. 1 ? 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 f and an esr of 3 ? 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 10 rev. 2.4, 2004-01-01 tle 4276 application information for variable output regulator tle 4276 v, sv, dv, gv the output voltage of the tle 4276 v can be adjusted between 2.5 v and 20 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. figure 5 application detail external components at output for variable voltage regulator the output voltage is calculated according to equation (1) : v q = ( r 1 + r 2 )/ r 2 v ref , neglecting i va (1) 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 (2) : r 2 < 50 k ? (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 r 1 and r 2 add an additional error to the output voltage tolerance. the operation range of the variable tle 4276 v is v q + 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 - v q aeb02804 current and saturation control internal reference 2.5 v typical 5 v ref r 2 r 1 c q 22 f q va 4
