TLE4275

5-V Low-Drop 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 Ordering Code Package P-TO252-5-1 (SMD) P-TO263-5-1 (SMD) P-TO220-5-11 P-TO220-5-12 P-TO263-5-1 P-TO252-5-1 Type TLE 4275 D Q67006-A9354 TLE 4275 G Q67006-A9343 TLE 4275 New type Functional Description Q67000-A9342 TLE 4275 S Q67000-A9442 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 Ω 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 µF and an ESR of ≤ 5 Ω within the opera...
