TLE4279GM

OPTIREG™ Linear TLE4279 5V low drop fixed voltag e regulator Features • Output voltage tolerance ≤ ±2% • 150 mA current capability • Very low current consumption • Early warning • Reset output low down to VQ = 1 V • Overtemperature protection • Reverse polarity proof • Adjustable reset threshold • Very low-drop voltage • Wide temperature range • Green Product (RoHS compliant) Potential applications General automotive applications. Product validation Qualified for Automotive Applications. Product Validation according to AEC-Q100/101 Description The OPTIREG™ Linear TLE4279 is an automotive voltage regulator with a 5 V fixed output, in a PG-DSO-8 or PG-DSO-14 package. 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. If the application requires pull-up resistors at the logic outputs (Reset, Sense Out) the TLE4269 with integrated resistors can be used. It is also possible to supervise the input voltage by using an integrated comparator to give a low voltage warning.

Data Sheet 8 Rev. 2.5 2018-11-19 OPTIREG™ Linear TLE4279 5V 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 (see Figure 4) 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 9 Rev. 2.5 2018-11-19 OPTIREG™ Linear TLE4279 5V 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. Both reset output and sense output are open collector outputs and have to be connected to 5 V output via external pull-up resistors ≥ 10 kΩ. For small tolerances of the reset delay the spread of the capacitance of the delay capacitor and its temperature coefficient should be noted.
