The 0.6 V dropout at full load means the input rail can sag to 2.1 V for a 1.5 V output before regulation is lost — useful in automotive or industrial systems where the supply bus dips during cranking or brownout. The single regulator is enabled via the Enable pin and includes a Reset output for power-good sequencing. ## PSRR at 100 Hz — why it matters for audio and sensor rails The 60 dB PSRR at 100 Hz means the regulator attenuates 100 Hz ripple (from a rectified mains or a switching pre-regulator) by a factor of 1000. For a 100 mVpp ripple on the input, the output sees only 100 µVpp — clean enough to power an analog front-end or a codec without additional post-filtering. Quiescent current is 30 µA typical, so the regulator's own draw is negligible in battery-backed systems. ## Package and thermal — the exposed pad is your heat path Housed in an 8-SOIC with exposed pad (SOIC-EP), the die's heat flows through the pad to the PCB copper. A thermal via array under the pad is expected for dissipating the dropout power at high input-output differentials — at 30 V in and 1.5 V out at 200 mA, the regulator dissipates 5.7 W, so the board layout must handle that thermal load. Protection includes over-temperature shutdown and short-circuit current limiting. The Enable pin allows the output to be gated by a microcontroller or a supervisor, and the Reset output signals when the output is within regulation — no external watchdog needed.","metaTitle":"MAX16910CASA9+ LDO Regulator, 200mA, 30V Input, 8-SOIC-EP","metaDescription":"Analog Devices MAX16910CASA9+ LDO regulator: 200mA output, 30V max input, 60dB PSRR at 100Hz, -40°C to 125°C, active production.
