Short Functional Description
The TLE 4252 is a monolithic integrated low-drop voltage tracking regulator in a very small SMD package P-TO252-5-1. It is designed to supply off-board systems, e.g. sensors in engine management systems under the severe conditions of automotive applications. Therefore the device is equipped with additional protection functions against reverse polarity and short circuit to GND and battery.

Features
• Output tracking tolerance to reference ≤ ±0.2%
• Output voltage adjust down to 1.5 V
• 250 mA output current capability
• Enable function
• Very low current consumption in OFF mode
• Wide operation range: up to 40 V
• Wide temperature range: -40 °C ≤ Tj ≤ 150 °C
• Output protected against short circuit to GND and Battery
• Overtemperature protection
• Reverse polarity proof
