OPTIREG™LinearTLE4263 5V low drop fixed voltage regulator The IC regulates an input voltage V in the range between 6V and 45V to an output voltage to V = 5.0V. A I Q,nom reset signal is generated for an output voltage of V < 4.5V. This voltage threshold can be decreased to 3.5V Q,rt 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 900µA to typical 0µA.

OPTIREG™LinearTLE4263 5V 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 1.35V, the external reset delay capacitor is discharged by the reset generator. When the voltage of the capacitor reaches the lower threshold V , a reset signal occurs at the reset output and is held until the upper threshold V is exceeded. If the reset DRL DU threshold input is connected to GND, reset is triggered at an output voltage of typ. 4.65V. 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 C is necessary for compensation of line influences. Using a resistor of approx. 1Ω in series I with C, the oscillating circuit consisting of input inductivity and input capacitance can be damped. The output I capacitor is necessary for the stability of the regulating circuit. Stability is ensured at values C ≥22µF and an Q ESR of ≤3Ω 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 Table3 Electrical characteristics V = 13.5V; -40°C < T < 125°C; V > 3.5V; (unless specified otherwise) I j INH Parameter Symbol Values Unit Note or TestCondition Min.
