The maximum input voltage is 42 V (65 V, 400 ms). Up to an input voltage of 26 V and for an output current up to 550 mA it regulates the output voltage within a P-TO252-5-1 (D-PAK) 2 % accuracy. The short circuit protection limits the output current of more than 650 mA. The device incorporates overvoltage protection and temperature protection that disables the circuit at unpermissibly high temperatures.

Reset Delay; connect a capacitor to ground for delay time adjustment. 5-V Output; block to ground with 22 F capacitor, ESR < 3 . 2 1998-11-01 Semiconductor Group TLE 4270 Application Description The IC regulates an input voltage in the range of 5.5 V < VI < 36 V to VQnom = 5.0 V. Up to 26 V it produces a regulated output current of more than 550 mA. Above 26 V the save-operating-area protection allows operation up to 36 V with a regulated output current of more than 300 mA. Overvoltage protection limits operation at 42 V. The overvoltage protection hysteresis restores operation if the input voltage has dropped below 36 V. A reset signal is generated for an output voltage of VQ < 4.5 V. The delay for power-on reset can be set externally with a capacitor. Design Notes for External Components An input capacitor CI is necessary for compensation of line influences. The resonant circuit consisting of lead inductance and input capacitance can be damped by a resistor of approx. 1 in series with CI. An output capacitor CQ is necessary for the stability of the regulating circuit. Stability is guaranteed at values of CQ 22 F and an ESR of < 3 . Circuit Description The control amplifier compares a reference voltage, which is kept highly accurate by resistance adjustment, to a voltage that is proportional to the output voltage and drives the base of a series transistor via a buffer. Saturation control as a function of the load current prevents any over-saturation of the power element. If the output voltage decreases below 4.5 V, an external capacitor CD on pin 4 (D) will be discharged by the reset generator. If the voltage on this capacitor drops below VDRL, a reset signal is generated on pin 2 (RO), i.e. reset output is set low. If the output voltage rises above 4.5 V, CD will be charged with constant current. After the power-on-reset time the voltage on the capacitor reaches VDU and the reset output will be set high again. The value of the power-on-reset time can be set within a wide range depending of the capacitance of CD. The IC also incorporates a number of internal circuits for protection against: * * * * Overload Overvoltage Overtemperature Reverse polarity Semiconductor Group 3 1998-11-01 TLE 4270 Temperature Sensor Saturation Control and Protection Circuit 5 Output Input 1 Control Amplifier Adjustment Bandgap Reference + - Buffer Reset Generator 2 Reset Output 4 Reset Delay 3 GND AEB01924 Figure 2 Block Diagram Semiconductor Group 4 1998-11-01 TLE 4270 Absolute Maximum Ratings Tj = - 40 to 150 C Parameter Symbol min.
