The IC regulates an input voltage up to 40 V to VQrated = 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 shortcircuit-proof and incorporates temperature protection that disables it at over-temperature. Dimensioning Information on External Components The input capacitor CI is necessary for compensating line influences. Using a resistor of approx. 1 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. Stability is guaranteed at values CQ 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 Semiconductor Group 2 1998-11-01 TLE 4276 Pin Configuration (top view) P-TO220-5-3 P-TO220-5-43 P-TO220-5-122 P-TO252-5-1 GND 1 5 1 Q INH N.C.
