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 environments. The IC protects itself in case of overload, over temperature, 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”.
