Linear Voltage Regulators for Automotive Applications

The TLE4254EJ S is a monolithic integrated low-dropout voltage tracking regulator with high accuracy in small PG- DSO-8 packages. The IC is designed to supply off-board systems, e. g. sensors in powertrain management systems under the severe conditions of automotive applications. Therefore, the IC 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 very high accuracy. The reference voltage applied directly to the adjust input or by an e.g. external resistor divider can be 2.0 V minimum. The output is able to drive loads up to 70 mA while the device follows with high accuracy the e. g. 5 V output of a main voltage regulator acting as a reference.

TLE42364G is a low dropout voltage regulator for 5 V supply in a PG-SOT223-4 SMD package. The IC regulates an input voltage V I in the range of 5.5 V < V I < 45 V to V Q,nom = 5 V. The maximum output current is more than 100 mA. The IC can be switched off via the enable input, which causes the current consumption to drop below 10 µA. The IC is protected against short circuit and overheat by the incorporated output current limitation and the over temperature shutdown.

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”.

TLE 4262 GM is a 5-V low-drop voltage regulator in a PG-DSO-14 or PG-DSO-20 SMD package. The maximum input voltage is 45 V. The maximum output current is more than 200 mA. The IC is short-circuit proof and includes a temperature protection which turns off the IC at overtemperature. The IC regulates an input voltage VI in the range of 6 V < V I < 45 V to V Q,nom = 5.0 V. A reset signal is generated for an output voltage of V Q,rt < 4.5 V. This voltage threshold can be decreased to 3.5 V by external connection of a voltage divider. The reset delay can be set externally with a capacitor. The IC can be switched off via the inhibit input, which reduces the current consumption from 900 µA to typical 0 µA.
