R1540x Series High Noise Immunity 42 V Input Voltage 70 mA Voltage Tracker for Automotive Applications NO.EC-513-190411 OVERVIEW The R1540x is a voltage tracker featuring input voltage in the range of 3.5 V to 42 V. Highly accurate output voltage which attributes to CE/ADJ pin achieves successful sequence control of the integrated off-board sensor module. Strong enough not to require the circuit to avoid external electromagnetic interference (EMI) and this contributes space saving. KEY BENEFITS  Excellent noise immunity provides effective shielding against EMI.  Lower stand-by current consumption leads to energy saving of the whole system to prolong battery life.  Response to requirements for sequence control in the system with integrated sensors.
