data sheet 2 rev. 2.6, 2007-03-20 tle 4276 functional description the tle 4276 is a low-drop vo ltage regulator in a to pack age. the ic regu lates an input voltage up to 40 v to v q,nom = 5.0 v (v50), 8.5 v (v85), 10 v (v10) and ad justable voltage (v). the maximum output current is 400 ma. the ic can be switched off via the inhibit input, which causes the current consumptio n to drop below 10 a. the ic is short-circuit- proof and includes temperature protection whic h turns off the device at overtemperature. dimensioning in formation on exte rnal 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 in ductivity and in put capacitance can be damped. the output capacitor c q is necessary for the st ability 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 volt age to a voltage that is proportional to the output voltage and drives the base of the seri es transistor via a buffe r. saturation control as a function of the load cu rrent prevents any oversaturati on of the power element. the ic also incorporates a nu mber of internal circuits for protection against: ? overload ? overtemperature ? reverse polarity
