Description

Description:
The TLE4252G is a monolithic integrated low-drop voltage tracking regulator in a very small SMD package PG-TO263-5. 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. With supply voltages up to 40 V, the output voltage follows a reference voltage applied at the adjust input with high accuracy. The reference voltage applied directly to the adjust input or by an e.g. external resistor divider can be 1.5 V minimum. The output is able to drive loads up to 250 mA. The TLE 4252 tracker can be switched into stand-by mode to reduce the current consumption to very low values. This feature makes the IC suitable for low-power battery applications.
Summary of 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 ≤ T j ≤ 150 °C
Output protected against short circuit to GND and Battery
Overtemperature protection
Reverse polarity proof
Green Product (RoHS compliant)
AEC Qualified
Benefits:
Efficient and accurate voltage replication
Heat distribution in the system
Robust tracking supply
