Built-in protection covers over-current, over-temperature, and short-circuit events — the LDO folds back or shuts down rather than exceeding the junction temperature limit.","metaTitle":"Texas Instruments LP3852ESX-1.8/NOPB LDO, 1.5A, 1.8V Fixed","metaDescription":"Texas Instruments LP3852ESX-1.8/NOPB LDO, 1.5A output, 1.8V fixed, 0.38V dropout at full load, 73dB PSRR, DDPAK-5, active.
