LP2951CSDX-3.0/NOPB

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

The LP2951CSDX-3.0/NOPB is a micropower voltage regulator from the LP2951-N series, manufactured by Texas Instruments. It provides a fixed 3.0 V output with an ensured 100-mA load current capability. The device operates within a 2.3 V to 30 V input voltage range and features extremely low quiescent current of 75 µA typical. It includes logic-controlled electronic shutdown and an error flag output for monitoring regulation status. The component is housed in an 8-pin WSON package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Features a logic-compatible shutdown pin that enables active control of the regulator state to minimize power consumption during inactive periods.
• Includes an open-drain error flag output that signals when the regulated voltage drops below the specified threshold due to input undervoltage.
• Provides high accuracy output voltage regulation with tight initial tolerance and low temperature coefficient suitable for precision applications.

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

• Battery-powered systems requiring extended operational life through low quiescent current operation
• Regulators with undervoltage shutdown capabilities for system protection
• High-efficiency linear regulators in portable electronics

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

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the fixed 3.0 V output configuration and WSON package type. Ensure compatibility with the required thermal management solutions for the surface-mount application. Cross-reference the datasheet revision history for any updates regarding electrical characteristics or recommended operating conditions prior to final design integration.

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

Select this component for designs requiring a fixed 3.0 V rail with high accuracy and low standby current. The inclusion of the shutdown feature makes it suitable for battery-operated devices where power conservation is critical. Consider the thermal resistance of the WSON package when determining heat dissipation requirements under maximum load conditions.
