That 30 dB roll-off above the switching-regulator crossover means upstream buck converter ripple at 2 MHz is attenuated by roughly 40 dB — enough to keep a 3.3 V analog rail clean for a 16-bit ADC front-end without a post-filter. ## Dropout and headroom — what 120 mV means at 500 mA Maximum dropout is 120 mV at the full 500 mA output. If the input rail is 3.3 V and the output is set to 3.0 V, the headroom is 300 mV — 180 mV above the dropout ceiling, so the output stays in regulation across load steps and temperature. Below that margin the LDO enters dropout and PSRR collapses. ## AEC-Q100 Grade 1 — where it sits in the vehicle That covers the under-hood and engine-bay temperature envelope — an ECU seeing 105°C on a summer grade still has 20°C of margin before the silicon junction exceeds the rated limit. ## Protection set and quiescent current Over-temperature, reverse polarity, short-circuit, and soft-start protection are integrated — no external supervisor or current-limit resistor needed. Quiescent current is 120 µA typical, supply current maxes at 160 µA, so in a battery-backed module that sleeps most of the time the LDO's own draw is negligible.","metaTitle":"MAX8902AATA/V+T LDO, 500mA, PSRR 92dB, AEC-Q100, 8-TDFN","metaDescription":"Analog Devices MAX8902AATA/V+T automotive LDO, 500mA output, 120mV dropout, PSRR 92dB-62dB (5-100kHz), AEC-Q100 Grade 1, active production, ROHS3.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"92dB ~ 62dB (5kHz ~ 100kHz)","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Programmable","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"500mA","Protection Features":"Over Temperature, Reverse Polarity, Short Circuit, Soft Start","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"5.5V","Voltage Dropout (Max)":"0.12V @ 500mA","Current - Supply (Max)":"160 µA","Voltage - Output (Max)":"4.7V","Supplier Device Package":"8-TDFN-EP (2x2)","Current - Quiescent (Iq)":"120 µA","Voltage - Output (Min/Fixed)":"1.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.39","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.39000","currency":"USD"},{"qty":10,"price":"$3.94200","currency":"USD"},{"qty":25,"price":"$3.72680","currency":"USD"},{"qty":100,"price":"$3.23000","currency":"USD"},{"qty":250,"price":"$3.06432","currency":"USD"},{"qty":500,"price":"$2.74962","currency":"USD"},{"qty":1000,"price":"$2.31896","currency":"USD"},{"qty":2500,"price":"$2.20301","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4d8bed696762ab8b4ce499b0fff65cf6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the PSRR of MAX8902AATA/V+T?","answer":"PSRR is 92 dB at 5 kHz and 62 dB at 100 kHz.
