The 65 dB PSRR at 1 kHz means this part rejects ripple from a switching preregulator by a factor of ~1800, which is adequate for most analog front-ends and wireless transceivers drawing under 200 mA. The -40°C to 125°C operating range spans industrial and automotive ambient requirements. ## Low quiescent current and protection suite for battery-powered analog rails Quiescent current is 120 µA typical, which keeps the regulator's own draw below 0.06% of the 200 mA load — important for battery-powered sensors that spend most of their time in a low-power idle state and wake briefly to transmit. The Enable control pin lets a microcontroller or supervisor gate the output — when pulled low the regulator drops into shutdown, further cutting supply current below the 120 µA Iq figure. ## 8-MSOP footprint and supply rails for integration into mixed-signal boards The supplier device package is 8-VSSOP, which is the same mechanical outline — a single PCB footprint serves both package codes.","metaTitle":"LP2988IMM-2.8/NOPB LDO Regulator, 200mA, 2.8V Fixed","metaDescription":"Texas Instruments LP2988IMM-2.8/NOPB: 200mA LDO, fixed 2.8V output, 65dB PSRR at 1kHz, -40 to 125°C.

This is a typical figure for a general-purpose LDO in this class — it attenuates 100 mV of ripple at 1 kHz down to roughly 56 µV at the output, sufficient for 12-bit analog circuits and most wireless transceivers."},{"question":"Does LP2988IMM-2.8/NOPB drop in as a replacement for TLV74333PDQNR?","answer":"No. LP2988IMM-2.8/NOPB outputs a fixed 2.8 V, while TLV74333PDQNR outputs 3.3 V. The packages differ (8-MSOP vs the TLV74333's package), and the TLV74333 has a lower 5.5 V maximum input versus 16 V on this part. The dropout and quiescent characteristics are not equivalent.
