Datasheet 8 Rev. 2.8 2019-07-30 OPTIREG™ Linear TLE4271-2 5-V low drop fixed voltage regulator Circuit description 4 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. The reset output RO is in high-state if the voltage on the delay capacitor CD is greater or equal VUD. The delay capacitor CD is charged with the current ID for output voltages greater than the reset threshold VRT. If the output voltage gets lower than VRT (‘reset condition’) a fast discharge of the delay capacitor CD sets in and as soon as VD gets lower than VLD the reset output RO is set to low-level. The time for the delay capacitor charge from VUD to VLD is the reset delay time tD. When the voltage on the delay capacitor has reached VUD and reset was set to high, the watchdog circuit is enabled and discharges CD with the constant current IDWD. If there is no rising edge observed at the watchdog input, CD will be discharge down to VLDW, then reset output RO will be set to low and CD will be charged again with the current IDWC until VD reaches VUD and reset will be set high again. If the watchdog pulse (rising edge at watchdog input WI) occurs during the discharge period CD is charged again and the reset output stays high. After VD has reached VUD, the periodical behavior starts again.

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. The IC can be switched off via the inhibit input, which causes the quiescent current to drop below 10 µA. A reset signal is generated for an output voltage of VQ < 4.5 V. The watchdog circuit monitors a connected controller. If there is no positive-going edge at the watchdog input within a fixed time, the reset output is set to low. The delay for power-on reset and the maximum permitted watchdog-pulse period 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 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. Reset circuitry If the output voltage decreases below 4.5 V, an external capacitor CD on pin D will be discharged by the reset generator. If the voltage on this capacitor drops below VDRL, a reset signal is generated on pin 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. 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: tD = CD × ∆V/ID (4.1) Definitions: • CD = delay capacitor Datasheet 10 Rev. 2.8 2019-07-30 OPTIREG™ Linear TLE4271-2 5-V low drop fixed voltage regulator Circuit description • tD = reset delay time • ID = charge current, typical 14 µA • ∆V = VUD, typical 1.8 V • VUD = upper delay timing threshold at CD for reset delay time 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 (4.2) VΙ t VINH VU, INH VL, INH t < t RR VQ VRT VD VUD t t RR dV Ι D = dt C D VLD VD, SAT VRO t tD VRO, SAT t Power on Thermal Reset Shutdown Figure 5 Datasheet Voltage Drop at Input Undervoltage at Output Secondary Load Spike Bounce Shutdown AET01985 Time response 11 Rev. 2.8 2019-07-30 OPTIREG™ Linear TLE4271-2 5-V low drop fixed voltage regulator Circuit description Watchdog timing V WΙ VΙ VQ VD t WΙ, tr t WD, P VUDW VLDW t WD, L VR t WΙ, tr = Figure 6 Datasheet (V UDW - VLDW ) Ι DWD C D ; t WD, P = (V UDW - VLDW ) (V UDW - VLDW ) (Ι DWC + Ι DWD ) t WD, L = C ; CD D Ι DWC .
