The TLE 4276 is a low-drop voltage regulator with an output voltage tolerance of ≤±4%, low-drop, inhibit input, very low current consumption, short-circuit protection, reverse polarity protection, and is suitable for use in automotive electronics.
The TLE4276 is a low-drop voltage regulator offered in TO‑220 and TO‑252 packages. It regulates an input voltage up to 40 V to fixed outputs of 5.0 V (V50), 8.5 V (V85), 10 V (V10) or an adjustable voltage, with a maximum output current of 400 mA. The device includes an inhibit input that reduces current consumption to below 10 pA, short‑circuit protection, and reverse‑polarity protection, making it suitable for automotive electronics.
The datasheet details absolute maximum ratings, operating temperature range (‑40 °C to 150 °C), pin definitions, and recommended external component values for stability. It also provides block diagrams, characteristic curves, and example application circuits to aid designers in implementing the regulator in their designs.
