LP3883ESX-1.2/NOPB

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

The LP3883ESX-1.2/NOPB is a fixed positive linear voltage regulator manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output voltage of 1.2 V with a maximum output current of 3 A. The device features an ultra-low dropout voltage of 210 mV at full load and a typical power supply rejection ratio (PSRR) of 80 dB. It operates within a junction temperature range of -40°C to +125°C and utilizes a TO-263-5 surface-mount package.

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

Ultra-low dropout performance for efficient voltage regulation under varying load conditions
High power supply rejection ratio to minimize noise impact on the output
Fast transient response capability to maintain stability during rapid load changes

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

Portable battery-powered equipment requiring low quiescent current
Post-regulation for switching regulators in embedded systems
Circuitry demanding stable 1.2 V logic levels

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

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the specific suffix 'NOPB' indicates RoHS compliance and lead-free status. Ensure the package type matches the required TO-263 footprint for PCB layout compatibility before finalizing procurement orders.

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

Select this component when a fixed 1.2 V output is required with high current capacity. Consider the thermal dissipation capabilities of the TO-263 package relative to the expected power loss. Evaluate input-to-output voltage differentials to ensure operation remains within the specified dropout limits for optimal efficiency.

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

This part belongs to the LP3883 series of fast-response ultra-low dropout linear regulators. The series is characterized by high performance and robustness suitable for demanding applications. The ESX variant specifically denotes the tape-and-reel packaging format within the TO-263 family.
