High Noise Immunity 42 V Input Voltage 70 mA Voltage Tracker for Automotive Applications
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.
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.
