LP3883ES-1.2

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

The LP3883ES-1.2/NOPB is a high-performance dual-rail low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It provides a fixed 1.2 V output with a maximum continuous current of 3 A. The device operates within an input voltage range of 1.426 V to 5.5 V and features a typical dropout voltage of 210 mV at full load. It exhibits a typical power supply rejection ratio (PSRR) of 80 dB and maintains a quiescent current of 60 nA. The component supports surface-mount installation in a TO-263-5 package and functions reliably across an operating temperature range from -40°C to +125°C.

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

Verify the specific suffix (e.g., NOPB) against the manufacturer's official datasheet to confirm lead-free compliance and exact electrical tolerances. Ensure the TO-263-5 package footprint matches your PCB design guidelines. Confirm that the fixed 1.2 V output aligns with your system requirements, as adjustable variants exist within the same family. Cross-reference the manufacturer part number with authorized distributors to avoid obsolete or counterfeit components.

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

Select this component when a fixed 1.2 V rail is required with high current capacity up to 3 A. Consider the ultra-low dropout characteristic if the input voltage margin is minimal. Evaluate the thermal performance in the TO-263-5 package based on expected power dissipation. Compare the 60 nA quiescent current against other LDOs if battery life is critical. Verify compatibility with the target input voltage range of 1.426 V to 5.5 V.
