Product validation Qualified for automotive applications. Product validation according to AEC-Q100/101. Description The OPTIREG™ Linear TLE4269 is an automotive voltage regulator with a 5 V fixed output. The maximum operating voltage is 45 V. The output is able to drive 150 mA load. The device features short-circuit protection. The thermal shutdown feature switches the output off when the junction temperature exceeds 150°C to ensure the device is not damaged by overheating. A reset signal is generated when the output voltage drops below VQ < 4.65 V. The reset threshold voltage can be decreased by an external connection of a voltage divider. The reset delay time can be set by an external capacitor. Reset and sense output have integrated pull-up resistors. If the integrated resistors are not required, the TLE4279 can be used instead. It is also possible to supervise the input voltage by using an integrated comparator to give a low voltage warning.

Data Sheet 9 Rev. 2.6 2018-11-20 OPTIREG™ Linear TLE4269 5 V low drop fixed voltage regulator Functional description 4 Functional description The control amplifier compares a reference voltage, made highly accurate by resistance balancing, with a voltage proportional to the output voltage and drives the base of the series PNP 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 gap for the delay capacitor discharge is the reset reaction time tRR. The reset threshold VRT can be decreased via an external voltage divider connected to the pin RADJ. In this case the reset condition is reached if VQ < VRT and VRADJ < VRAQDJ, TH. Dimensioning the voltage divider (Figure 5) according to: (4.1) V RAD ( J, TH ) × ( R ADJ1 + R ADJ2 ) V THRES = ---------------------------------------------------------------------------R ADJ2 the reset threshold can be decreased down to 3.5 V. If the reset-adjust-option is not needed the RADJ-pin should be connected to GND causing the reset threshold to go to its default value (typ. 4.65 V). A built in comparator compares the signal of the pin SI, normally fed by a voltage divider from the input voltage, with the reference and gives an early warning on the pin SO. It is also possible to superwise another voltage e.g. of a second regulator, or to build a watchdog circuit with few external components. Data Sheet 10 Rev. 2.6 2018-11-20 OPTIREG™ Linear TLE4269 5 V low drop fixed voltage regulator Application information 5 Application information The input capacitor CI is necessary for compensating 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 CQ is necessary for the stability of the regulating circuit. Stability is guaranteed at values ≥ 10 μF and an ESR ≤ 10 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. 5.1 Application diagram ΙΙ ΙQ Ι CΙ 470 nF 1000 μF Q TLE 4269 Ι SΙ VΙ SI D VSΙ GND ΙD CD 100 nF R Ι GND VR CQ 22 μF RADJ1 Ι RADJ VQ RADJ SO VSO VRADJ VD RADJ2 AES01670 Figure 5 Measuring circuit VI t VQ < t RR V RT dV I D = dt C D VD t V UD V LD V RO td t t RR VRO, SAT t Power-on-Reset Figure 6 Data Sheet Thermal Shutdown Voltage Dip at Input Undervoltage Secondary Spike Overload at Output AED01542 Reset timing diagram 11 Rev. 2.6 2018-11-20 OPTIREG™ Linear TLE4269 5 V low drop fixed voltage regulator Application information Sense Input Voltage VSI, High VSI, Low t Sense Output High Low t AED03049 Figure 7 Data Sheet Sense timing diagram 12 Rev. 2.6 2018-11-20 OPTIREG™ Linear TLE4269 5 V low drop fixed voltage regulator Application information 5.2 Typical performance characteristics Charge current ID versus junction temperature Tj ΙD Switching voltage VUD and VLD versus junction temperature Tj AED01803 16 μA 14 V Ι = 13.5 V V C = 1.0 V 12 AED01804 3.2 VD V 2.8 V Ι = 13.5 V 2.4 10 2.0 8 1.6 6 1.2 4 0.8 2 0.4 VUD VLD 0 -40 0 40 80 0 -40 120 C 160 0 40 80 Tj Tj Drop voltage Vdr versus output current IQ Reset adjust switching threshold VRADJ,TH versus junction temperature Tj AED01805 500 V dr 120 C 160 AED01806 1.7 V V RADJ, TH 1.6 mV 400 1.5 1.4 300 1.3 Tj = 125 C 200 1.2 Tj = 25 C 1.1 100 1.0 0 0 30 60 90 120 mA 0.9 -40 180 ΙQ Data Sheet 0 40 80 120 C 160 Tj 13 Rev. 2.6 2018-11-20 OPTIREG™ Linear TLE4269 5 V low drop fixed voltage regulator Application information Current consumption IQ versus input voltage VI Output voltage VQ versus input voltage VI AED01807 30 Ι q mA VQ V 25 10 20 8 RL = 33 Ω 15 6 10 RL = 50 Ω 4 RL = 50 Ω RL = 100 Ω 5 0 AED01808 12 2 RL = 200 Ω 0 10 20 30 0 40 V 50 0 2 4 6 VΙ Sense threshold VSI versus junction temperature Tj VΙ AED01809 AED01671 5.2 VQ V V Ι = 13.5 V 1.5 V 10 Output voltage VQ versus junction temperature Tj 1.6 V SI 8 V 5.1 V Ι = 13.5 V 1.4 5.0 Sense Output High 1.3 4.9 Sense Output Low 1.2 4.8 1.1 4.7 1.0 -40 0 40 80 4.6 -40 120 C 160 Tj Data Sheet 0 40 80 120 C 160 Tj 14 Rev. 2.6 2018-11-20 OPTIREG™ Linear TLE4269 5 V low drop fixed voltage regulator Application information Output current IQ versus input voltage VI Current consumption IQ versus output current IQ AED01810 350 AED01811 12 Ι Q mA Ι q mA 300 10 V Ι = 13.5 V Tj = 25 C 250 8 Tj = 25 C 200 6 150 Tj = 125 C 4 100 2 50 0 0 10 20 30 0 40 V 50 Current consumption Iq versus output current IQ Ιq 0 20 40 60 80 mA 120 ΙQ VΙ – AED01812 1.6 mA 1.4 V Ι = 13.5 V Tj = 25 C 1.2 1.0 0.8 0.6 0.4 0.2 0 0 10 20 30 40 mA 50 ΙQ Data Sheet 15 Rev. 2.6 2018-11-20 OPTIREG™ Linear TLE4269 5 V low drop fixed voltage regulator Package information 6 Package information 1.27 0.1 0.41 +0.1 -0.06 0.2 8 5 Index Marking 1 4 5 -0.21) M 0.19 +0.0 6 B 8° MAX. 4 -0.21) 1.75 MAX. 0.175 ±0.07 (1.45) 0.35 x 45° 0.64 ±0.25 A B 8x 6 ±0.2 A 1) Does not include plastic or metal protrusion of 0.15 max. per side 2) Lead width can be 0.61 max. in dambar area GPS01229 1) Figure 8 PG-DSO-8 Figure 9 PG-DSO-14 1) 1) Dimensions in mm Data Sheet 16 Rev. 2.6 2018-11-20 OPTIREG™ Linear TLE4269 5 V low drop fixed voltage regulator 2.65 MAX. 0.35 x 45˚ 1.27 0.35 0.1 20x +0.15 2) 0.2 20x 20 0.4 +0.8 0.23 +0.09 7.6 -0.2 1) 8˚ MAX. 2.45 -0.2 0.2 -0.1 Package information 10.3 ±0.3 11 1 10 12.8 -0.2 1) Index Marking 1) Does not include plastic or metal protrusion of 0.15 max. per side 2) Does not include dambar protrusion of 0.05 max. per side Figure 10 PG-DSO-20 GPS05094 1) Green product (RoHS compliant) To meet the world-wide customer requirements for environmentally friendly products and to be compliant with government regulations the device is available as a green product.
