Fixed 3.03V rail for noise-sensitive loads
PSRR measures 50 dB to 55 dB across the 1 kHz to 10 kHz band, which covers the switching frequency of many DC-DC converters and the audio range. That level of ripple rejection is adequate for powering analog front-ends, codec supplies, or sensor bias rails where a switcher's ripple would otherwise couple into the signal path. The operating temperature range of -40°C to 125°C covers automotive under-hood, industrial motor drives, and outdoor telecom enclosures. Protection features include over-current, over-temperature, and short-circuit shutdown — standard for a modern LDO but worth noting for designs that cannot tolerate a latched fault. The enable pin (active high) allows external sequencing or shutdown control without a separate load switch.
Package and rework considerations
Available in Tape & Reel or Cut Tape options from distribution. The ROHS3 compliance means no exemption-listed halogens or phthalates — clean for RoHS-driven BOMs.
Lifecycle and sourcing
The NOPB suffix confirms lead-free / RoHS3 compliance, which is the standard for new designs. For BOM planning, this is a straightforward active part to qualify.
