EZ1086CM-3.3TRT

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

The EZ1086CM-3.3TRT is a low dropout positive linear regulator manufactured by Semtech Corporation, designed to provide a fixed 3.3V output voltage with a maximum load current capability of 1.5A. The device features an internal circuit architecture optimized for operation with an input-to-output differential as low as 1V, ensuring stable regulation under varying load conditions. Dropout voltage specifications are fully defined as a function of the load current, guaranteeing performance up to a maximum dropout of 1.5V at peak output current. This component belongs to the LT1086 family, offering robust line and load regulation suitable for power supply applications requiring efficient voltage conversion from higher DC sources.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the manufacturer designation carefully, as the part number prefix 'EZ' may indicate a specific distributor or regional variant distinct from the standard 'LT' prefix used in official Linear Technology datasheets. Confirm that the TRT suffix corresponds to the correct tape and reel packaging format required for your assembly process. Ensure compatibility with the intended thermal management solution, as the DDPAK package requires adequate heat sinking for sustained 1.5A operation. Cross-reference the exact part number with the supplier's certified documentation to avoid substitution errors with similar LDO regulators.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 3.3V rail is needed with high current capacity and minimal voltage headroom requirements. It is suitable for replacing older LT1086 variants where the specific 3.3V fixed output is desired without external resistor networks. Consider the thermal dissipation capabilities of the DDPAK package relative to the expected ambient temperature and load profile. Ensure the input voltage source can maintain the necessary differential for the specified dropout characteristics under all operating conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This regulator is part of the broader LT1086 series of 1.5A low dropout positive regulators, which includes adjustable versions and other fixed voltage options such as 2.85V, 3.6V, 5V, and 12V. The series is known for its fast transient response and high ripple rejection ratios. The EZ1086CM-3.3TRT specifically provides the 3.3V fixed output option, packaged in a 4-pin (3+Tab) DDPAK housing, distinguishing it from lower current alternatives like the LT1117 series.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include the LT1086CM-3.3 and APL1086-3.3, which share identical pinouts and electrical specifications. Verify thermal resistance values and package dimensions when swapping between manufacturers to ensure mechanical fit and adequate heat dissipation.
