LP2989IMM-3.0/NOPB

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

The LP2989IMM-3.0/NOPB is a micropower low-dropout linear voltage regulator manufactured by Texas Instruments, featuring a fixed 3.0 V output and a maximum continuous load current of 500 mA. It operates within an input voltage range of 2.1 V to 16 V and maintains a typical dropout voltage of 310 mV at full load. The device incorporates internal circuitry for overcurrent limiting, thermal shutdown, and reverse battery protection. Designed for surface-mount applications, it utilizes an 8-pin VSSOP package and supports operation across an extended industrial temperature range from -40°C to +125°C.

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

• Integrated reverse battery protection allows safe operation even when the input voltage polarity is reversed relative to ground.
• Built-in thermal shutdown and current limit circuits protect the device against overheating and excessive load conditions.
• Micropower architecture ensures minimal quiescent current consumption during standby or light-load operations.

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

• Battery-powered portable electronic devices requiring efficient power management
• Industrial control systems operating in harsh environmental conditions
• Communication equipment needing stable voltage regulation under varying loads

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

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as manufacturing processes may vary. Check for specific ordering suffixes that indicate tape-and-reel packaging versus cut-tape options. Ensure compatibility with existing PCB footprints and reflow soldering profiles before finalizing procurement decisions.

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

Select this regulator for designs requiring high input voltage tolerance up to 16 V combined with low quiescent current. Consider the VSSOP-8 package constraints regarding thermal dissipation capabilities at maximum load currents. Evaluate system requirements against the fixed 3.0 V output constraint, as adjustable variants are not available within this specific part number configuration.
