Product details
Overview
LT1460KCS3-3.3#TRMPBF from Analog Devices (formerly Linear Technology) is a micropower precision series voltage reference in 3-lead SOT-23 package, delivering 3.3V output with ±0.5% initial accuracy, 50ppm/°C max temperature coefficient, and 180µA typical supply current. It operates from VOUT + 0.9V to 30V input, supplies up to 20mA, and requires no output capacitor-enabling use in portable instrumentation and high-resolution ADC biasing.
For engineers reviewing the LT1460KCS3-3.3#TRMPBF datasheet, LT1460KCS3-3.3#TRMPBF pinout, LT1460KCS3-3.3#TRMPBF application, or LT1460KCS3-3.3#TRMPBF equivalent, key selection criteria include its guaranteed operation over 0°C to 70°C, reverse-battery protection, low thermal regulation (2.5–10 ppm/mW), and stability with capacitive loads up to 1µF without external compensation.
Technical Context
The LT1460KCS3-3.3#TRMPBF employs curvature-compensated bandgap architecture to achieve low drift and high DC accuracy. Its internal thin-film resistor trimming enables ±0.5% output voltage tolerance at 25°C, with full-range specification across 0°C to 70°C ambient.
It functions as a three-terminal series reference: input (VIN), ground (GND), and output (VOUT). Unlike shunt references, it draws only 145–220µA quiescent current and does not require an external current-setting resistor-reducing power loss and extending battery life in low-power systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3333AIDBVR | ±0.1% initial accuracy, 10ppm/°C drift, 3.9µA supply current, same SOT-23-3 package | Lower power but lower accuracy; optimized for sub-1µA systems with relaxed precision | Select REF3333AIDBVR when ultra-low quiescent current dominates over absolute accuracy requirements |
| ADR3433ARJZ-R7 | ±0.1% accuracy, 10ppm/°C drift, 120µA supply current, SOT-23-5 package (extra pins for enable/trim) | Higher accuracy and lower drift, but requires 5-pin layout and lacks reverse-battery protection | Select ADR3433ARJZ-R7 when highest stability is critical and board space permits 5-pin footprint |
Compared with REF3333AIDBVR and ADR3433ARJZ-R7, the LT1460KCS3-3.3#TRMPBF trades tighter initial accuracy for robust reverse-battery protection, higher output drive (20mA vs ≤10mA), and guaranteed operation without output capacitance-making it uniquely suited for cost-sensitive, ruggedized portable designs.

FAQ
What is the maximum load current supported by the LT1460KCS3-3.3#TRMPBF?
The LT1460KCS3-3.3#TRMPBF supports up to 20mA of continuous output current while maintaining specified line and load regulation. At 20mA, dropout voltage increases to 1.4V, and output voltage change remains within ±140ppm/mA. This capability allows direct interface with ADC reference inputs, op-amp bias networks, and small-signal transducers without buffering.
Does the LT1460KCS3-3.3#TRMPBF require an output capacitor for stability?
No, the LT1460KCS3-3.3#TRMPBF is internally compensated and stable with 0–1µF capacitive loads. Unlike many references, it does not require an external output capacitor-reducing BOM count, PCB area, and potential drift from capacitor aging. Stability is verified per Figure 3 and Figure 5 in the official LT1460 datasheet.
What is the guaranteed operating temperature range for the LT1460KCS3-3.3#TRMPBF?
The LT1460KCS3-3.3#TRMPBF is specified and guaranteed over 0°C to 70°C (Commercial grade). Its electrical characteristics-including ±0.5% output voltage accuracy and 50ppm/°C temperature coefficient-are validated across this full range, with no derating required. The part is not rated for extended industrial (–40°C to 85°C) or automotive temperatures.
How does reverse battery protection work in the LT1460KCS3-3.3#TRMPBF?
The LT1460KCS3-3.3#TRMPBF incorporates internal circuitry that blocks current flow when VIN is driven negative relative to GND. At –15V reverse input, leakage remains ≤10µA, preventing damage and eliminating the need for external series diodes. This feature is intrinsic to the device's architecture and requires no external components or layout changes.
What is the typical supply current of the LT1460KCS3-3.3#TRMPBF at 25°C?
The LT1460KCS3-3.3#TRMPBF draws 180µA typical supply current at 25°C with no load. Over temperature and process variation, it ranges from 145µA to 220µA. This micropower consumption enables multi-year operation from CR2032 coin cells in low-duty-cycle sensor nodes and handheld instruments.
