EZ1086CT-3.3T

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

The EZ1086CT-3.3T is a fixed-output positive low dropout linear voltage regulator manufactured by Semtech Corporation, housed in a TO-220 package with three pins. It provides a stable 3.3V output voltage and supports a maximum continuous load current of 1.5A. The device is engineered for high efficiency, featuring a typical dropout voltage of 1.3V at full rated current. Internal circuitry ensures reliable operation with input voltages ranging from 2.55V to 25V. Key protection mechanisms include internal current limiting and thermal shutdown to safeguard the component under fault conditions.
