tle 4276 data sheet version 2 2 2000-02-14 functional description the tle 4276 is a low-drop voltage regulator in a to220 package. the ic regulates an input voltage up to 40 v to v qrated = 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 m a. the ic is short- circuit-proof and incorporates temperature protection that disables it at over-tempera- ture. dimensioning information on external components the input capacitor c i is necessary for compensating line influences. using a resistor of approx. 1 w 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 3 22 m f and an esr of 3 w 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

tle 4276 data sheet version 2 10 2000-02-14 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 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 (equ. 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 w (equ. 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 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 C v q aeb02804 current and saturation control internal reference 2.5 v typical q v a v ref r 2 r 1 c q 22 m f
