Analog Devices Inc. LT1460JCS3-5#TRMPBF

Overview

LT1460JCS3-5#TRMPBF from Analog Devices (formerly Linear Technology) is a micropower precision series voltage reference delivering 5.000V ±0.5% initial accuracy in a 3-lead SOT-23 package, with 50ppm/°C max temperature coefficient, 200µA max supply current, and stable operation into capacitive loads up to 1µF - ideal for portable instrumentation and low-power ADC/DAC biasing.

For engineers reviewing the LT1460JCS3-5#TRMPBF datasheet, LT1460JCS3-5#TRMPBF pinout, LT1460JCS3-5#TRMPBF application, or LT1460JCS3-5#TRMPBF equivalent, key selection criteria include output accuracy at 0°C–70°C, dropout voltage of 0.9V min, reverse battery protection, no-output-capacitor requirement, and compatibility with space-constrained PCB layouts.

Technical Context

The LT1460JCS3-5#TRMPBF uses curvature-compensated bandgap architecture to achieve low thermal drift and high DC accuracy without external trimming. Its internal thin-film resistor network is laser-trimmed for 0.5% output voltage tolerance across the commercial temperature range.

It operates as a three-terminal series reference with active pass element, enabling sourcing up to 20mA while maintaining line regulation ≤130ppm/V and load regulation ≤100ppm/mA at 20mA - distinguishing it from shunt references by eliminating idle current waste and supporting direct connection to low-impedance analog rails.

FAQ

What is the maximum load current supported by the LT1460JCS3-5#TRMPBF?

The LT1460JCS3-5#TRMPBF supports up to 20mA of continuous sourcing current while maintaining specified accuracy and regulation. At 20mA, load regulation is ≤100ppm/mA (≤2mV change), and dropout voltage increases to 1.4V. Short-circuit current is rated at 40mA, but sustained operation above 20mA may degrade long-term stability and thermal performance.

Does the LT1460JCS3-5#TRMPBF require an output capacitor for stability?

No, the LT1460JCS3-5#TRMPBF is internally compensated and remains stable with output capacitance ranging from 0µF to 1µF - including ceramic, tantalum, and electrolytic types. This eliminates the need for external compensation components, simplifying layout and reducing BOM count in compact designs where board space is constrained.

What is the minimum input voltage required for the LT1460JCS3-5#TRMPBF to regulate at 5V?

The LT1460JCS3-5#TRMPBF requires a minimum input-to-output differential voltage of 0.9V. Therefore, to maintain 5.000V output, VIN must be ≥5.9V under no-load conditions. At 10mA load, the dropout rises to 1.3V, requiring VIN ≥6.3V. Input voltage must not exceed 30V absolute maximum.

How does reverse battery protection work in the LT1460JCS3-5#TRMPBF?

The LT1460JCS3-5#TRMPBF incorporates internal circuitry that blocks conduction when the input terminal is driven negative relative to GND. At –15V reverse input, leakage current is limited to ≤10µA, preventing damage to the die or downstream circuitry - a critical feature for field-serviceable battery compartments where polarity reversal is possible.

Is the LT1460JCS3-5#TRMPBF compatible with lead-free reflow soldering processes?

Yes, the LT1460JCS3-5#TRMPBF features a lead-free finish and is qualified for standard Pb-free reflow profiles per JEDEC J-STD-020, with peak temperatures up to 260°C. The SOT-23 package has a maximum soldering temperature rating of 300°C for 10 seconds, ensuring robustness during manufacturing.
