LDO, ADJ, AEC-Q100, 2-45V, 0.25A, HSOIC8; Output Type: Adjustable; Input Voltage Min: 3.5V; Input Voltage Max: 40V; Fixed Output Voltage Nom.: -; Adjustable Output Voltage Min: 2V; Adjustable Output Voltage Max: 45V; Output Cu

The IC is designed to supply off-board systems, e. g. sensors in engine 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 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 250 mA. The TLE4253 tracker can be set into shutdown mode in order to reduce the quiescent current to an extremely low value. This makes the IC suitable to low-power battery applications.
