PG-SCT595-5
Functional Description
The TLE4250-2 is a monolithic integrated low dropout voltage tracker in a tiny SMD package PG-SCT595-5 with
excellent thermal resistance. It is designed to supply off-board loads (e.g. sensors) in automotive environment.
The IC protects itself in case of overload, overtemperature, reverse polarity as well as output short circuit to battery
and ground.
Supply voltages up to V_I = 45 V are regulated to a reference voltage applied at the adjust input “ADJ” with high
accuracy. The output “Q” is able to drive loads up to 50 mA.
In order to reduce the quiescent current to a minimum, the TLE4250-2 can be switched to stand-by mode by
setting the adjust/enable input “ADJ/EN” to “low”.
