TLE 4252 is a low-drop voltage tracking regulator with output tracking tolerance and output voltage adjustment. It has an output current capability of 250 mA and can operate in a wide temperature range from -40°C to 150°C. In addition, it has functions such as short circuit protection, reverse polarity protection, and overtemperature protection. The regulator is designed to supply off-board systems in automotive applications.
The TLE4252 is a monolithic low‑drop tracking regulator designed for automotive sensor and off‑board systems. It tracks a reference voltage applied to the ADJ pin with high accuracy, supports an adjustable output down to 1.5 V, and can deliver up to 250 mA while maintaining low quiescent current in standby mode.
The device includes reverse‑polarity and short‑circuit protection, operates over a wide temperature range (‑40 °C to 150 °C), and is supplied in a small P‑TO252‑5‑1 SMD package. Detailed electrical characteristics, pin definitions, and application circuits are provided in the datasheet.
