For automotive applications please refer to the Infineon TLx (TLE, TLS, TLF....) voltage regulator products. Description The IFX7805 monolithic 3-terminal positive voltage regulator employs internal current-limiting, thermal shutdown and safe-area compensation, making it extremely robust. The IFX7805 is available in a fixed 5V version and is capable of delivering an output current of 1A. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. This linear voltage regulator is designed for a wide variety of applications and suitable for use in harsh environments. The short-circuit current limit, limits the output current of the device. The safe-area protection feature limits the internal power dissipation, in case the internal power dissipation becomes too high, the thermal shutdown implemented prevents the device from overheating. PG-TO-220-3 The 5V voltage regulator is available in the TO-252, TO-220 and TO-263 packages.

Thermal shutdown protects the regulator from immediate destruction due to high temperature conditions by turning it off. The thermal shutdown is set to a typical value of 175°C. Operating a linear regulator over the maximum junction temperature significantly reduces the life time of the device and pushes the operating variables outside their specified limits. The device also has an unbolt short circuit protection feature that keeps the output current within the specified bounds to protect both the regulator and the load. The safe-area compensation reduces the output short-circuit current as the voltage across the power stage is increased. It is recommended that the regulator input is bypassed with a capacitor if the regulator is connected to the power supply filter with long lengths, or if the load capacitance at the output is large. A 0.33µF or larger tantalum or other capacitor, with a low internal impedance at high frequencies, should be chosen. The bypass capacitor should be mounted with the shortest possible leads directly across the input terminals of the regulator. Fixed Output Regulator VOUT VIN IFX7805 CIN = 0.33 µF COUT = 0.1 µF 1) A capacitor at the output is recommended for improved transient response . 2) An output capacitor is required if the regulator is located at an appreciable distance from the supply filter Figure 3 Datasheet Typical Application Diagram 13 Rev. 1.0, 2013-07-15 IFX7805 Package Outlines 7 Package Outlines 6.5 +0.15 -0.10 2.3 +0.05 -0.10 4.57 0.9 +0.08 -0.04 B 0.51 MIN. 0.15 MAX. per side 5.4 0.8 ±0.15 9.9 ±0.5 6.22 -0.2 1 ±0.1 A ±0.1 3x 0.75 ±0.1 0...0.15 0.5 +0.08 -0.04 2.28 1 ±0.1 0.25 M A B 0.1 All metal surfaces tin plated, except area of cut.
