| Low Drop Voltage Regulator TLE 4274 Features * * * * * * * * * * Output voltage 5 V, 8.5 V or 10 V Output voltage tolerance 4% Current capability 400 mA Low-drop voltage Very low current consumption Short-circuit proof Reverse polarity proof Suitable for use in automotive electronics Green Product (RoHS compliant) version of TLE 4274 AEC qualified P-TO220-3-1 PG-TO220-3-1 ^ Functional Description The TLE 4274 is a low drop voltage regulator available in a TO220, TO252 and TO263 package. The IC regulates an input voltage up to 40 V to VQrated = 5.0 V (V50), 8.5 V (V85) and 10 V (V10). The maximum output current is 400 mA. The IC is short-circuit proof and incorporates temperature protection that disables the IC at overtemperature. A 3.3 V and 2.5 V version is also available. For information about the low output voltage types please refer to the data sheet TLE 4274 / 3.3 V; 2.5 V.

Using a resistor of approx. 1 in series with CI, the oscillating of input inductivity and input capacitance can be damped. The output capacitor CQ is necessary for the stability of the regulation circuit. Stability is guaranteed at values CQ 22 F and an ESR of 3 within the operating temperature range. Circuit Description The control amplifier compares a reference voltage 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 oversaturation of the power element. The IC also includes a number of internal circuits for protection against: * * * Overload Overtemperature Reverse polarity Data Sheet 2 Rev. 1.6, 2007-01-23 TLE 4274 PG-TO220-3-1 PG-TO252-3-11 PG-TO263-3-1 GND Q AEP02512 GND Q AEP02281 GND Q AEP01957 Figure 1 Table 1 Pin No. 1 2 3 I Pin Configuration (top view) Pin Definitions and Functions Symbol GND Q Function Input; block to ground directly at the IC with a ceramic capacitor.
