Up to 26 V it produces a regulated output current of more than 650 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.

The resonant circuit consisting of lead inductance and input capacitance can be damped by a resistor of approx. 1 Ω 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 µF and an ESR of < 3 Ω. Datasheet 13 Rev. 1.9 2020-02-25 OPTIREG™ Linear TLE4270-2 5-V low drop fixed voltage regulator Application information 5.2 Reset circuitry 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 VDL, a reset signal is generated on pin 2 (RO), i.e. reset output is set low. If the output voltage rises above the reset threshold, 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. 5.3 Reset timing The power-on reset delay time is defined by the charging time of an external capacitor CD which can be calculated as follows: CD = (∆t × ID,c)/∆V (5.1) Definitions: • CD = delay capacitors • ∆t = reset delay time trd • ID,c = charge current, typical 14 µA • ∆V = VDU, typical 1.8 V VDU = upper reset timing threshold at CD for reset delay time trd = ∆V × CD/ID,c (5.2) The reset reaction time trr is the time it takes the voltage regulator to set the reset out LOW after the output voltage has dropped below the reset threshold. It is typically 1 µs for delay capacitor of 47 nF. For other values for CD the reaction time can be estimated using the following equation: trr ≈ 20 s/F × CD (5.3) VI < trr VQ VRT dV ID, c = dt CD VDU VD VDL trr trd VRO Power-ON Reset Figure 5 Datasheet Thermal Shutdown Voltage Drop at Input Undervoltage Secondary Load Spike Bounce AES01927 Reset time response 14 Rev. 1.9 2020-02-25 OPTIREG™ Linear TLE4270-2 5-V low drop fixed voltage regulator Package information 6 Package information 4.4 10 ±0.2 1.27 ±0.1 0...0.3 B 0.05 2.4 0.1 4.7 ±0.5 2.7 ±0.3 7.55 1) 1±0.3 9.25 ±0.2 (15) A 8.5 1) 0...0.15 5 x 0.8 ±0.1 0.5 ±0.1 4 x 1.7 0.25 M A B 8˚ MAX. 0.1 B 1) Typical Metal surface min.
