The ±1% initial tolerance and 100 ppm/°C temperature coefficient define the voltage accuracy across temperature — adequate for 8- to 12-bit ADC references or general-purpose bias rails where a tighter bandgap is not required. ## Automotive temperature grade and noise floor Qualified to AEC-Q100, the part operates over a -40°C to +125°C junction temperature range — this is the under-hood automotive band. An engine-control module or transmission controller that sees 105°C ambient on a hot day still has margin before the reference drifts outside its datasheet limits. For a precision ADC reference driving a 16-bit converter at low sampling rates, this noise floor integrates into the output — the effective resolution is limited by the reference noise, not the converter's own quantization. A downstream RC filter at the reference input can knock down the wideband noise, but the 0.1–10 Hz band is dominated by the reference itself. ## Package and supply integration Supplied in a 5-pin SOT-23-5 (SC-74A) package — a common footprint that fits into compact PCB layouts without requiring a board respin from most existing SOT-23-5 reference designs. Quiescent supply current is 100 µA — low enough for battery-powered sensor nodes that spend most of their time in sleep mode, where the reference's own draw is a meaningful fraction of the system budget. The series topology means the output is low-impedance and does not require an external resistor to set the current, unlike a shunt reference.","metaTitle":"LM4128DQ1MF3.0/NOPB Texas Instruments Voltage Reference","metaDescription":"Active AEC-Q100 series voltage reference from Texas Instruments.
