LP2966IMMX-3325

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

The LP2966IMMX-3325/NOPB is a dual-channel low-dropout (LDO) voltage regulator manufactured by Texas Instruments, formerly National Semiconductor. It provides two fixed positive output voltages of 2.5 V and 3.3 V with a maximum output current of 150 mA per channel. The device operates within an input voltage range supporting ultra-low dropout performance, characterized by a maximum dropout voltage of 135 mV at 100 mA load. It features high line regulation of 0.1 mV/V and load regulation of 0.1 mV/mA. The unit functions in a VSSOP-8 surface-mount package across an extended temperature range from -40°C to +125°C.

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

Verify the complete part number includes the /NOPB suffix to confirm lead-free compliance and RoHS adherence as specified in official documentation. Confirm the manufacturer designation reflects Texas Instruments, which acquired National Semiconductor, to ensure accurate sourcing of genuine components. Cross-reference the VSSOP-8 package marking against official datasheets to prevent counterfeit substitution during procurement.

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

Select this component when dual fixed outputs are required without external feedback resistors. Ensure the application maintains sufficient input-to-output differential to stay within the specified 135 mV dropout limit at peak loads. Verify that the thermal dissipation capabilities of the VSSOP-8 package align with the expected power loss in the target environment.
