Trade Name:L7983PU33R
Brand:ST
Particular Year:23+
Package:10-DFN
Delivery Date:New and Original
Stock: 1000pcs
The L7983PU33R is a step-down monolithic switching regulator based on a peak current mode architecture that delivers up to 300 mA DC voltage. The output voltage is adjustable from 0.85 V to VIN. The wide input voltage range and adjustable UVLO thresholds are compliant with 12 V, 24 V, and 48 V industrial bus standards. The "Low Power Mode" (LCM) is designed for applications that operate in idle mode. As a result, it maximises efficiency at light loads with controlled output voltage ripple.
