Product Overview

STEVAL-L6981CDR evaluation board is based on the L6981CDR synchronous monolithic step-down regulator capable of delivering up to 1.5A DC. Its wide input voltage range makes the device suitable for a broad range of applications. The device implements peak current mode architecture in an SO 8L package with internal compensation to minimize design complexity and size. The L6981 is available in low consumption mode (LCM) and low noise mode (LNM) versions. LCM maximizes efficiency at light load with controlled output voltage ripple, making the device extremely suitable for battery-powered applications. LNM makes the switching frequency constant and minimizes the output voltage ripple overload current range, meeting the specification for noise sensitive applications. The EN pin manages the enable/disable function. The typical shutdown current is 2µA when disabled.
  • 3.5V to 38V operating input voltage, output voltage from 0.85 V to VIN
  • 1.5A DC output current
  • Internal compensation network
  • Internal soft-start
  • Enable function
  • Overvoltage protection
  • Output voltage sequencing
  • Thermal protection
  • Synchronization with external clock for LNM devices
