Product details
Overview
LM4130CIM5X-4.1 from Texas Instruments is a precision micropower low-dropout voltage reference IC delivering 4.096 V output with ±0.1% initial accuracy, 20 ppm/°C temperature coefficient, and ≤275 mV dropout at 10 mA - used as a stable reference in high-resolution ADCs, portable instrumentation, and battery-powered data acquisition systems.
For engineers reviewing the LM4130CIM5X-4.1 datasheet, LM4130CIM5X-4.1 pinout, LM4130CIM5X-4.1 application, or LM4130CIM5X-4.1 equivalent, key selection criteria include initial voltage tolerance, tempco over −40°C to +85°C, supply current ≤75 μA, load regulation ≤60 ppm/mA, and SOT23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The LM4130CIM5X-4.1 implements a CMOS bandgap architecture with EEPROM-based curvature, tempco, and accuracy correction - enabling post-assembly calibration to overcome plastic-package-induced shifts. It operates without mandatory output capacitance and supports capacitive loads up to 100 µF.
Unlike shunt references, it draws only 75 μA quiescent current and sustains full accuracy across −40°C to +85°C while delivering up to 20 mA output current. Its 4.096 V nominal output aligns with 12-bit DAC/ADC full-scale ranges requiring precise binary-scaled references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096 V ±0.1% (ensured at 25°C; enables direct interface with 12-bit systems) |
| Tempco | 20 ppm/°C (−40°C to +85°C; ensures <±1.4 mV drift over full industrial range) |
| Dropout Voltage | ≤275 mV @ 10 mA (allows operation from 4.37 V supply in 4.5 V systems) |
| Supply Current | ≤75 μA (enables multi-year battery life in always-on sensor nodes) |
| Load Regulation | ≤60 ppm/mA (output shift <250 μV over 0–20 mA load change) |
| Line Regulation | ≤250 ppm/V (input rejection maintains stability with noisy or varying supplies) |
| Output Noise | 245 μVPP (0.1–10 Hz; suitable for 16-bit measurement front-ends) |
Pinout & Package
SOT23-5 surface-mount package (2.92 mm × 1.6 mm × 1.1 mm), thermally enhanced with exposed pad (not electrically connected), rated for 125°C junction temperature and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | 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 | No Connection | Internally terminated; must remain unconnected on PCB |
| Pin 4 | Input Supply (VIN) | Accepts 4.37–5.5 V input; bypassing with 0.1 µF improves transient immunity |
| Pin 5 | Reference Output (VREF) | Delivers 4.096 V; sources up to 20 mA; stable with 0–100 µF output capacitance |
Key Features
| Feature | Design Value |
|---|---|
| EEPROM-based trimming | Corrects assembly-induced voltage shift and tempco drift at package level - no laser trimming required |
| Capacitor-free operation | Stable without output capacitor; eliminates BOM cost and layout area for decoupling |
| Low-quiescent-current LDO architecture | 75 μA supply current enables use in energy-harvesting and coin-cell applications |
| High-output-current capability | 20 mA sourcing supports direct driving of ADC reference inputs and op-amp bias networks |
| Extended tempco specification | 20 ppm/°C guaranteed over −40°C to +85°C - not just typical or limited-range value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3040AIDBZR | 4.096 V, ±0.2% initial accuracy, 50 ppm/°C tempco, 50 μA supply current | Lower quiescent current but looser accuracy and higher tempco; lacks EEPROM trim | Preferred where ultra-low power dominates over long-term stability |
| ADR3440ARJZ-R7 | 4.096 V, ±0.1% initial accuracy, 10 ppm/°C tempco, 120 μA supply current | Tighter tempco but higher supply current; requires 1 µF output capacitor | Selected when sub-10 ppm/°C drift is critical and board space allows extra capacitor |
Compared with REF3040AIDBZR and ADR3440ARJZ-R7, the LM4130CIM5X-4.1 offers the best balance of moderate quiescent current (75 μA), tight initial accuracy (±0.1%), and robust tempco (20 ppm/°C) without mandatory external capacitance - making it optimal for compact, battery-operated industrial sensors where layout area and long-term calibration stability are constrained.

FAQ
What is the operating temperature range for LM4130CIM5X-4.1?
The LM4130CIM5X-4.1 is specified for full accuracy over −40°C to +85°C, with extended operational capability up to +125°C. Its 20 ppm/°C temperature coefficient is guaranteed across the −40°C to +85°C range, ensuring predictable drift behavior in industrial environments where thermal cycling occurs.
Does LM4130CIM5X-4.1 require an output capacitor?
No, the LM4130CIM5X-4.1 is stable without an output capacitor and supports capacitive loads from 0 to 100 µF. Adding a capacitor improves load transient response but is optional - eliminating this component reduces BOM count and PCB area, which is advantageous in miniaturized designs where the LM4130CIM5X-4.1 is deployed.
What does the 'C' grade signify in LM4130CIM5X-4.1?
The 'C' in LM4130CIM5X-4.1 denotes the initial accuracy grade: ±0.1% output voltage tolerance at 25°C and a guaranteed temperature coefficient of 20 ppm/°C over −40°C to +85°C. This grade balances cost and performance for industrial-grade applications where tighter specs than 'D' or 'E' are needed but 'A' or 'B' grades are unnecessary.
Can LM4130CIM5X-4.1 drive a 20 mA load continuously?
Yes, the LM4130CIM5X-4.1 is rated for continuous 20 mA output current sourcing. Its low dropout voltage (≤275 mV @ 10 mA) and thermal design support this load under worst-case conditions, provided PCB copper area meets minimum recommendations and ambient temperature remains within −40°C to +85°C.
Is LM4130CIM5X-4.1 pin-compatible with other LM4130 variants?
Yes, all LM4130 variants - including LM4130CIM5X-4.1, LM4130AIM5X-2.5, and LM4130DIM5X-4.1 - share identical SOT23-5 pinout and footprint. Pin 1 and Pin 3 are NC, Pin 2 is GND, Pin 4 is VIN, and Pin 5 is VREF; no PCB redesign is needed when substituting between voltage options or accuracy grades.
