Voltage Tracker Description
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.
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.
