Built-in over-temperature and short-circuit protection allow the device to survive output faults without external clamp diodes — the enable pin (active high) lets a system controller gate the output rail for sequenced power-up.","metaTitle":"Texas Instruments LP5907MFX-4.5/NOPB LDO, 250mA, 4.5V","metaDescription":"Texas Instruments LP5907MFX-4.5/NOPB LDO regulator, 250mA output, 4.5V fixed, 90dB PSRR, SOT-23-5.
