LT1461CCS8-3#PBF

Voltage Reference Overview

The LT1461CCS8-3#PBF is a micropower precision low dropout series voltage reference manufactured by Analog Devices Inc. It provides a fixed 3V output with an initial accuracy of ±0.08% and a temperature coefficient of 5 ppm/°C. The device operates within a commercial temperature range of 0°C to +70°C and draws a typical supply current of 35µA, with a maximum of 70µA. It features a shutdown pin for power management and supports up to 100mA output short-circuit current. The component is housed in an 8-lead plastic SOIC package.

Voltage Reference Feature Summary

• Combines high accuracy and low drift with low supply current and high output drive capability
• Utilizes advanced curvature compensation techniques and trimmed precision thin-film resistors
• Includes a shutdown feature to switch full load currents and enable system power down
• Incorporates thermal shutdown protection against overload conditions

Voltage Reference Applications

• A/D and D/A Converters
• Precision Regulators
• Handheld Instruments
• Power Supplies

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging when sourcing. Confirm the CCS8 designation corresponds to the 0.08% accuracy grade and 5 ppm/°C temperature coefficient. Ensure the operating environment remains within the specified 0°C to +70°C commercial range. Check for automotive-grade alternatives if wider temperature ranges are required.

Voltage Reference Selection Notes

Select this part for applications requiring a stable 3V reference with micropower consumption. The low dropout voltage ensures efficiency in battery-powered systems. Consider the 100mA output capability for driving moderate loads directly. Verify that the 0.08% initial accuracy meets the system error budget requirements without additional calibration.

Voltage Reference Part Context

This component belongs to the LT1461 family of micropower precision low dropout series voltage references. The family offers various output voltages including 2.5V, 3V, 3.3V, 4.096V, and 5V. Different letter grades (A, B, C, D) denote varying levels of initial accuracy and temperature coefficients.
