R1540x-Y Series High Noise Immunity 42 V Input Voltage 70 mA Voltage Tracker for Industrial Applications
NO.EY-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. This is a high-reliability semiconductor device for industrial applications (-Y) that has passed both the screening at high temperature and the reliability test with extended hours.
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.
