Functional Description

TLE 4263 is a 5-V low drop voltage regulator in a SMD

package PG-DSO-14-30, PG-DSO-20-35, or

PG-DSO-8-16. The maximum input voltage is 45 V. The

maximum output current is more than 200 mA. The IC is

short-circuit proof and incorporates temperature

protection which turns off the IC at overtemperature.

The IC regulates an input voltage

in the range of 6 V <

< 45 V to

Q,nom

= 5.0 V. A reset signal is generated for

an output voltage of

Q,rt

< 4.5 V. This voltage threshold

can be decreased to 3.5 V 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 900

A to typical 0

TLE 4263 Choosing External Components The input capacitor CI is necessary for compensation of 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 is necessary for the stability of the regulating circuit. Stability is guaranteed at values ≥ 22 µF and an ESR of ≤ 3 Ω within the operating temperature range.

TLE 4263 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 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.

TLE 4263 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 = (trd × ID,ch)/∆V (1) Definitions: • • • • • CD = delay capacitor trd = reset delay time ID,ch = charge current, typical 60 µA ∆V = VDU, typical 1.

TLE 4263 Reset Switching Threshold The present default value is typ. 4.65 V. When using the TLE 4263 the reset threshold can be set to 3.5 V < VQ,rt < 4.6 V by connecting an external voltage divider to pin RADJ. The calculation can be easily done since the reset adjust input current can be neglected. If this feature is not needed, the pin has to be connected to GND. VQ,rt = (1 + R1/R2) × VRADJ,th (2) Definitions: • • VQ,rt = reset threshold VRADJ,th = comparator reference voltage, typical 1.
