概述
The R1540 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 regulator can be used under high temperature environment. It offers the maximum operating temperature of 105°C for consumer applications, and 125°C for industrial and automotive applications.
特点
- Excellent noise resistance 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.
