EZ1583CMTRT

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The EZ1583CMTRT is a high-performance positive voltage regulator from the EZ158X family, manufactured by Semtech. It is designed for applications requiring very low dropout voltage at rated currents of 7, 5, 3, and 1.5 amps. The device features an adjustable output voltage with a maximum differential input-output voltage of 12 V and a minimum of 2.5 V. It operates in a D2PAK package (TO-263) with 4 pins. Key electrical characteristics include a maximum dropout voltage of 0.8 V, a maximum line regulation of 0.064 %/V, and a maximum load regulation of 0.4%.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Provides superior dropout characteristics to reduce heat dissipation compared to regular LDOs when supplying lower voltages from higher available supplies.
• Offers excellent regulation over variations in line, load, and temperature conditions.
• Supports remote sense operation to compensate for trace, connector, and other resistive losses.
