| 5-V Low Drop Fixed Voltage Regulator TLE 4275 Features * * * * * * * * * * * Output voltage 5 V 2% Very low current consumption Power-on and undervoltage reset Reset low down to VQ = 1 V Very low-drop voltage Short-circuit-proof Reverse polarity proof Suitable for use in automotive electronics ESD protection > 4 kV Green Product (RoHS compliant) version of TLE 4275 AEC qualified P-TO220-5-11 PG-TO220-5-11 P-TO252-5-11 PG-TO252-11 Functional Description The TLE 4275 is a monolithic integrated low-drop voltage regulator in a 5-pin TO-package. An input voltage up to 45 V is regulated to VQ,nom = 5.0 V. The IC is able to drive loads up to 450 mA and is short-circuit proof. At overtemperature the TLE 4275 is turned off by the incorporated temperature protection. A reset signal is generated for an output voltage VQ,rt of typ. 4.65 V. The delay time can be programmed by the external delay capacitor.

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 5 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 incorporates a number of internal circuits for protection against: * * * Overload Overtemperature Reverse polarity Data Sheet 2 Rev. 1.7, 2007-02-19 TLE 4275 PG-TO252-5-11 GND PG-TO220-5-11 PG-TO220-5-12 1 RO DQ 5 AEP02580 PG-TO263-5-1 GND Q RO D IEP02527 GND Q RO D AEP02756 GND Q D RO IEP02528 Figure 1 Table 1 Pin No. 1 2 3 4 5 I RO Pin Configuration (top view) Pin Definitions and Functions Symbol Function Input; block to ground directly at the IC by a ceramic capacitor.
