- Output voltage tolerance ≤ ±2% 200 mA outpu t capability Low-drop voltage Very low standby cu rrent consumption Overtemperature protection Reverse polarity protection Short-circuit proof Adjustable reset threshold Wide temperature range Suitable for use in automotive electronics Green Product (RoHS compliant) AEC Qualified Functional Description TLE 4262 GM is a 5-V low-drop voltage regulator in a PG-DSO-14 or PG-DSO-20 SMD package. The maximum input voltage is 45 V. The maximum output current is more than 200 mA. The IC is short-circuit proof and includes a temperature protection which turns off the IC at overtemperature. The IC regulates an input voltage VI in the range of 6 V < VI < 45 V to VQ,nom = 5.0 V. A reset signal is generated for an output voltage of VQ,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 with a capacitor. The IC can be switched off via the inhibit input, which reduces the current consumption from 900 µA to typical 0 µA.
Data Sheet 2 Rev. 2.8, 2008-05-19 TLE 4262 Dimensioning Information on 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 circui t. Stability is guara nteed at values ≥ 22 µF and an ESR of ≤ 3 Ω within the operating temperat ure range. For small toleranc es of the rese t delay, the spread of the capacitance of the dalay capacitor and its temperature coefficient should be noted.

Data Sheet 4 Rev. 2.8, 2008-05-19 TLE 4262 Circuit Description The control amplifier compares a reference voltage, which is ke pt 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 1.35 V, the external reset delay capacitor is discharged by th e reset generator. If the voltag e on the capacitor reaches the lower threshold VDRL, a reset signal is issued on the reset output and not cancelled again until the upper threshold VDU is exceeded. If the reset threshold input is connected to GND, reset is triggered at an output voltage of 4.5 V. The IC can be switched at the TTL-compatible, low-active inhibit input. It also includes a number of internal circuits for protection against: Overload Overtemperature Reverse polarity Figure 2 Block Diagram AEB01081 Control Amplifier Buffer Reference Bandgap Adjustment Protection Circuit Control and SaturationTemperature Sensor Reset Generator I Q D RO RADJ 3-5, 10-1214 INH GND 913
