LP5907SNX-2.75

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

The LP5907SNX-2.75/NOPB is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, providing a nominal output voltage of 2.75V with a tolerance of ±2%. It supports an input voltage range from 2.2V to 5.5V and delivers up to 250mA of continuous load current. The device operates within a junction temperature range of –40°C to 125°C and features very low quiescent current of 12µA when enabled. It utilizes a 4-pin X2SON (DQN) surface-mount package.

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

Verify the complete part number includes the /NOPB suffix to ensure compliance with RoHS standards and absence of lead. Confirm the DQN package designation matches the required footprint. Validate that the specific 2.75V fixed output variant is available through authorized distribution channels.

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

Select this component for applications requiring stable power delivery to sensitive RF or analog circuits. Ensure the input voltage remains above the minimum threshold while accounting for dropout voltage at maximum load. Verify that external ceramic capacitors meet the specified ESR requirements for stability.

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