Rated for -40°C to 125°C, this LDO handles under-hood automotive, outdoor telecom cabinets, and factory-floor enclosures without derating. The TSOT-23-5 package is small enough for a multi-layer compact PCB but still hand-solderable with a fine tip — no hot-air station required for a field swap.
The ADP170AUJZ-2.5-R7 carries an active lifecycle status with ROHS3 compliance.
Power supply rejection ratio is 73 dB at 1 kHz, rolling off to 47 dB at 100 kHz. This makes it a strong choice for cleaning up ripple from a switching converter feeding a 2.5 V analog or RF supply.
The ADP1713AUJZ-3.0-R7 is a close functional sibling with similar PSRR (72 dB at 1 kHz) but a 3.0 V fixed output. The ADP122AUJZ-3.3-R7 offers a 3.3 V output but with lower PSRR (60 dB from 10 kHz to 100 kHz). Neither is a pin-for-pin replacement — output voltage and PSRR profile differ — but they serve the same LDO class for alternate voltage rails.
