It is capable of providing a guaranteed 2.500V output with a temperature range of ±14.7mV/°C, and an input voltage range of 1.02V to 5.5V.

Application Field

LT1460ACS8-2.5#PBF voltage reference are widely used in battery powered devices, such as cell phones and portable media players, as well as other precision high stability applications such as instrumentation, instrument amplifiers, data converters, SMPS (Switch Mode Power Supplies) and A/D and D/A converters. With its low quiescent current and output noise, it is ideal for battery-operated applications.

Working Principle

The LT1460ACS8-2.5#PBF works by sensing the reference voltage, providing a very accurate and stable output level. It uses two voltage references, an N-channel MOSFET for the reference voltage and an FET for the output voltage control. This ensures very accurate and stable output voltages even under changing temperatures and load conditions. The output is further regulated by a feedback loop, which allows the device to adjust itself automatically based on the load or temperature changes. This feedback loop also helps the device to maintain a high degree of accuracy and stability.
