TLS125D0EJ | Automotive Tracking LDO, 250 mA, DSO-8-EP package, Power Good

概要

The TLS125D0EJ is an Automotive low-dropout voltage tracking regulator (LDO) with high Tracking Accuracy, Reverse Current Protection and Power Good in DSO-8 (exposed pad) Package.

The OPTIREG™ linear TLS125D0EJ is a monolithic integrated low-dropout voltage tracking regulator with high accuracy in small PG-DSO-8 exposed pad package. The TLS125D0EJ is designed to supply off-board systems, for example sensors in powertrain management systems under the severe conditions of automotive applications. Therefore, the TLS125D0EJ is equipped with protection functions against reverse polarity and against short circuit to GND and battery.

Up to a supply voltage of 40 V and output currents up to 250 mA, the output voltage follows the reference voltage that is applied to the ADJ input with very high accuracy. The required minimum reference voltage at ADJ is 2.0 V.
