Datasheet Ricoh R1540

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.
