The supplier device package is listed as 4-DSBGA. ## Protection and control An enable pin lets you gate the output for sequenced power-up or low-power sleep modes. The regulator includes over-temperature and short-circuit protection — standard for this class, but worth noting if the rail feeds a load that can fault to ground. Maximum supply current is 230µA, so the enable pin is the real way to cut draw when the rail is idle. ## Sourcing and lifecycle Status is Active per the manufacturer. The NOPB suffix confirms RoHS3 compliance.","metaTitle":"LP5900XRX-2.8/NOPB LDO Regulator, 2.8V Fixed Output, 150mA","metaDescription":"TI LP5900XRX-2.8/NOPB linear regulator: 2.8V fixed output, 150mA, PSRR 85dB~40dB (100Hz~100kHz), 50µA Iq, 4-DSBGA.

The maximum input is 5.5V, so a 5V rail is within the safe operating range with 0.5V of headroom. The regulator will deliver a clean 2.8V output from a 5V supply."},{"question":"What does the PSRR of 85dB ~ 40dB (100Hz ~ 100kHz) mean in practice?","answer":"At 100Hz the PSRR is 85dB, meaning ripple on the input is attenuated by a factor of about 18,000. At 100kHz it drops to 40dB (factor of 100). This makes the part effective at cleaning up low-frequency ripple from a switching pre-regulator, but less effective at high-frequency noise — you still need a bypass cap close to the output pin for the MHz-range hash."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP5900XRX-2.8-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP5900XRX-2.8-NOPB when reusing this data.
