LM1084IT-ADJ/NOPB – TEXAS INSTRUMENTS

The LM1084IT-ADJ/NOPB is a 1.5A adjustable positive voltage regulator in a TO-220-5 (PDIP) package, specifically lacking lead-free properties (NOPB). It’s a member of the LM1084 family, distinguished by its adjustable output voltage, allowing for precise voltage setting via external resistors. The input voltage range typically spans 7V to 40V, enabling its use in a wide variety of applications. Output voltage is adjustable from 1.23V to 37V, though practical limits are often constrained by the input voltage and thermal considerations. The device features thermal shutdown and current limiting for robust operation and protection against overload. Its internal current limiting is approximately 1.5A, with higher currents achievable with appropriate heatsinking._x000D_

Unlike fixed-voltage regulators, the LM1084IT-ADJ/NOPB offers design flexibility, eliminating the need for multiple fixed-voltage regulators in systems requiring various voltage rails. Its relatively low quiescent current contributes to improved efficiency, especially beneficial in battery-powered applications. However, the absence of lead-free properties necessitates careful consideration of environmental regulations and compliance. Typical applications include post-regulation of switching power supplies, creating custom voltage rails within a larger system, and powering analog circuits requiring precise and stable voltage sources. Its ease of use and adjustable nature make it a versatile component for prototyping and production.
