Product details
Overview
LM4130AIM5X-4.1 from Texas Instruments is a precision micropower low-dropout voltage reference IC delivering 4.096 V output with ±0.05% initial accuracy, 10 ppm/°C temperature coefficient, and ≤275 mV dropout at 10 mA - used in high-resolution ADC/DAC biasing, portable instrumentation, and battery-powered data acquisition systems.
For engineers reviewing the LM4130AIM5X-4.1 datasheet, LM4130AIM5X-4.1 pinout, LM4130AIM5X-4.1 application, or LM4130AIM5X-4.1 equivalent, key selection criteria include guaranteed full-accuracy operation from −40°C to +85°C, no required output capacitor, 20 mA output drive capability, and SOT23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The LM4130AIM5X-4.1 uses EEPROM-trimmed CMOS bandgap architecture to correct curvature, tempco, and initial accuracy at package level - eliminating assembly-induced voltage shift common in laser-trimmed references. It operates as a series (not shunt) reference with internal curvature compensation.
No external output capacitor is required for stability, even under full 20 mA load or up to 100 µF capacitive loading. Its low 75 µA supply current and 275 mV dropout enable direct use from single-cell Li-ion or 3.3 V rails without pre-regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096 V ±0.05% - enables precise 12-bit DAC/ADC full-scale calibration without scaling resistors |
| Tempco | 10 ppm/°C (−40°C to +85°C) - ensures ≤±0.5 mV drift over industrial temperature range |
| Dropout Voltage | ≤275 mV @ 10 mA - supports regulation from 4.37 V input (e.g., 3.3 V LDO + margin) |
| Supply Current | ≤75 µA - extends battery life in always-on sensor nodes beyond 10 years on CR2032 |
| Load Drive | 20 mA source capability - directly drives ADC reference inputs and op-amp bias networks |
| Output Noise | 245 µVPP (0.1–10 Hz) - suitable for 16-bit SAR ADCs without additional filtering |
| Line Regulation | 75 ppm/V (VIN ≥ VREF + 500 mV) - maintains accuracy despite input rail variation in unregulated supplies |
Pinout & Package
SOT23-5 surface-mount package (2.92 mm × 1.6 mm × 1.02 mm), moisture sensitivity level 1, RoHS-compliant, rated for −40°C to +125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | NC | No connection - internally terminated; must remain unconnected on PCB |
| Pin 2 | Ground | Reference return path - requires low-impedance connection to system ground plane |
| Pin 3 | NC | No connection - internally terminated; must remain unconnected on PCB |
| Pin 4 | VIN | Positive supply input - bypass with 0.1 µF ceramic capacitor for noise rejection |
| Pin 5 | VREF | Stable 4.096 V output - sources up to 20 mA; stable with 0–100 µF capacitive loads |
Key Features
| Feature | Design Value |
|---|---|
| EEPROM-based trimming | Enables post-assembly correction of tempco and accuracy - eliminates laser-trimming cost and yield loss |
| Capacitor-free stability | Operates stably with zero output capacitance - reduces BOM count and board area in ultra-compact designs |
| Low-output impedance | <1 Ω output impedance - minimizes voltage drop under dynamic load steps in precision analog front-ends |
| Extended temperature operation | Functional to +125°C junction - supports under-hood automotive and industrial control applications |
| High-grade initial accuracy | A-grade tolerance (±0.05%) - meets requirements for metrology-grade calibration without external trimming |

FAQ
What is the operating temperature range for the LM4130AIM5X-4.1?
The LM4130AIM5X-4.1 is specified for full accuracy operation from −40°C to +85°C, with extended functionality up to +125°C junction temperature. This makes LM4130AIM5X-4.1 suitable for industrial control cabinets and automotive under-hood environments where ambient temperatures exceed standard commercial ranges.
Does the LM4130AIM5X-4.1 require an output capacitor?
No, the LM4130AIM5X-4.1 is stable without any output capacitor and remains stable with capacitive loads up to 100 µF. Adding a capacitor improves transient response but increases turn-on time - so LM4130AIM5X-4.1 offers design flexibility where board space or startup timing is constrained.
What does the 'A' grade signify in LM4130AIM5X-4.1?
The 'A' in LM4130AIM5X-4.1 denotes the highest accuracy grade: ±0.05% initial output voltage tolerance and ≤10 ppm/°C temperature coefficient over −40°C to +85°C. This grade is validated per TI's Statistical Quality Control methods and is required for metrology-grade and 16-bit+ data conversion systems using LM4130AIM5X-4.1.
Can the LM4130AIM5X-4.1 drive a 20 mA load continuously?
Yes, the LM4130AIM5X-4.1 is rated to source up to 20 mA continuously while maintaining output voltage accuracy within specification. Thermal derating applies above +85°C ambient, but at room temperature with minimal PCB copper, LM4130AIM5X-4.1 sustains full load without exceeding its 125°C maximum junction temperature.
How is the 4.1 in LM4130AIM5X-4.1 related to its output voltage?
The "4.1" in LM4130AIM5X-4.1 is a manufacturer-specific ordering suffix indicating the 4.096 V output variant - not a rounded value. All electrical characteristics in the datasheet (e.g., dropout, noise, line regulation) are measured and guaranteed specifically for the 4.096 V version of LM4130AIM5X-4.1, not 4.1 V.
