Fixed 2.8V LDO for noise-sensitive rails
The LP2980AIM5X-2.8/NOPB: Its 63 dB PSRR at 1 kHz makes it a candidate for cleaning up supply noise on analog or RF rails where a 2.8 V rail is specified. The SOT-23-5 footprint is a common low-dropout package, and the enable pin allows the rail to be gated by a system supervisor or GPIO.
Dropout and quiescent current at 50 mA load
Maximum dropout voltage is 0.22 V at 50 mA output.
This ordering code carries an Obsolete lifecycle status.
The 125°C junction rating means the 50 mA output is thermally feasible in those environments provided the PCB copper area around the SOT-23-5 pad is adequate for heat sinking.
