It integrates Enable, Power Good, Reset, and Sequencing control, making it a fit for powering mixed-voltage digital cores and I/O banks in a single package. ## PSRR and noise rejection for sensitive rails PSRR is specified at 65 dB at 1 kHz (typical) and 60 dB at 1 kHz, meaning the regulator attenuates 1 kHz ripple on the input by a factor of roughly 1800×. For a 100 mVpp switching ripple at 1 kHz, the output sees about 55 µVpp — clean enough for most ADC and PLL supply rails. The 250 µA quiescent current is modest for a dual 1A/2A LDO — it keeps the self-heating low in standby but does not compete with ultra-low-Iq parts for always-on battery applications. ## Protection and temperature range for industrial use Built-in Over Current, Over Temperature, Reverse Polarity, and Under Voltage Lockout (UVLO) protect the regulator and downstream loads from fault conditions. The -40°C to 125°C operating range covers industrial enclosures, motor drives, and outdoor telecom gear. The 2A channel dropout is not specified in the same entry, so budget headroom based on the typical dropout curve in the datasheet.
