The maximum output current is 200 mA. The IC is short-circuit proof and incorporates temperature protection which turns off the IC at overtemperature. Data Sheet www.infineon.com/OPTIREG-Linear 1 Rev. 3.0 2018-10-04 OPTIREG™ Linear TLE4263 5 V low drop fixed voltage regulator The IC regulates an input voltage VI in the range between 6 V and 45 V to an output voltage to VQ,nom = 5.0 V. A reset signal is generated for an output voltage of VQ,rt < 4.5 V. This voltage threshold can be decreased to 3.5 V by external connection of a voltage divider. The reset delay can be set externally by a capacitor. The integrated watchdog logic supervises the connected microcontroller. The IC can be switched off via the inhibit input, which causes the current consumption to drop from 900 µA to typical 0 µA.

Data Sheet 7 Rev. 3.0 2018-10-04 OPTIREG™ Linear TLE4263 5 V low drop fixed voltage regulator Functional description 4 Functional 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 the series transistor via a buffer. Saturation control as a function of the load current prevents any over-saturation of the power element. If the externally scaled down output voltage at the reset threshold input drops below 1.35 V, the external reset delay capacitor is discharged by the reset generator. When the voltage of the capacitor reaches the lower threshold VDRL, a reset signal occurs at the reset output and is held until the upper threshold VDU is exceeded. If the reset threshold input is connected to GND, reset is triggered at an output voltage of typ. 4.65 V. A connected microcontroller will be monitored through the watchdog logic. In case of missing pulses at pin W, the reset output is set to “low”. The pulse sequence time can be set in a wide range with the reset delay capacitor. The IC can be switched at the TTL-compatible, low-active inhibit input. The IC also incorporates a number of internal circuits for protection against: • Overload • Overtemperature • Reverse polarity 4.1 Choosing external components The input capacitor CI is necessary for compensation of line influences. Using a resistor of approx. 1 Ω in series with CI, the oscillating circuit consisting of input inductivity and input capacitance can be damped. The output capacitor is necessary for the stability of the regulating circuit. Stability is ensured at values CQ ≥ 22 µF and an ESR of ≤ 3 Ω within the operating temperature range. For small tolerances of the reset delay the spread of the capacitance of the delay capacitor and its temperature coefficient should be noted. 4.2 Electrical characteristics Table 3 Electrical characteristics VI = 13.5 V; -40°C < Tj < 125°C; VINH > 3.5 V; (unless specified otherwise) Parameter Symbol Values Min.

When using the TLE4263 the reset threshold can be set to 3.5 V < VQ,rt < 4.6 V by connecting an external voltage divider to pin RADJ. The calculation can be easily done since the reset adjust input current can be neglected. If this feature is not needed, the pin must be connected to GND.
