LP3996SDX-3333/NOPB

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

The LP3996SDX-3333/NOPB is a dual low-dropout (LDO) voltage regulator from Texas Instruments, designed for portable applications requiring high power supply rejection ratio (PSRR). It integrates two independent LDOs: one with a fixed 3.3V output and another with a fixed 3.3V output, both capable of delivering up to 150mA. The device operates with an input voltage range of 1.8V to 5.5V. Key electrical parameters include a typical dropout voltage of 200mV at 150mA load and a quiescent current of 40µA. It features enable pins for power management and is housed in a 6-pin SOT-23 package.

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

Verify the exact part number LP3996SDX-3333/NOPB against manufacturer datasheets to ensure compatibility with your design specifications. Confirm that the SOT-23 package and pinout match your PCB layout. Check for any recent revisions or obsolescence notices from Texas Instruments before finalizing procurement decisions.

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

Select this component when dual 3.3V rails are needed with minimal board space. Ensure input voltage stays within 1.8V to 5.5V range. Consider thermal performance if operating near maximum load currents. Verify PSRR requirements align with application noise sensitivity.

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

Part of Texas Instruments' LP399x family of dual LDO regulators. Designed for cost-sensitive, space-constrained portable applications. Shares common architecture with other variants differing in output voltages or current ratings.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for direct substitutes like LP3996SDX-18/NOPB or LP3996SDX-25/NOPB if different output voltages are acceptable. Verify pin compatibility and electrical characteristics before substitution.
