LP2986IMMX-3.3/NOPB

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

The LP2986IMMX-3.3/NOPB is a micropower, ultra low-dropout fixed voltage regulator manufactured by Texas Instruments (formerly National Semiconductor). It provides a fixed 3.3 V output with a maximum load current of 200 mA. The device operates from an input voltage range of 2.1 V to 16 V and features a typical dropout voltage of 180 mV at full load. Quiescent current is specified at 1 uA. It includes internal protection against overcurrent, thermal overload, and short circuits. The component is housed in an 8-pin VSSOP package and supports operation across an extended temperature range of -40°C to +125°C.

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

Verify the manufacturer origin, as Texas Instruments acquired National Semiconductor. Confirm the specific suffix indicates RoHS compliance and lead-free status. Ensure the VSSOP-8 package matches your PCB footprint requirements. Check for any specific handling precautions related to the small outline package during assembly.

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

Select this component when a fixed 3.3 V rail is required with minimal static power draw. The 200 mA output capability suits moderate load applications. Consider the 180 mV dropout characteristic to ensure adequate headroom between input and output voltages. Verify that the VSSOP-8 package is suitable for your automated assembly process.

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

This part belongs to the LP2986 series of micropower LDO regulators. The series offers both fixed and adjustable output versions. The 'IMM' designation typically refers to the VSSOP-8 package variant. The '/NOPB' suffix generally denotes a non-halogenated, lead-free product compliant with environmental directives.
