Product details
Overview
LM4130EIM5-2.5/NOPB from Texas Instruments is a precision micropower low-dropout voltage reference IC delivering 2.500 V output with ±0.5% initial accuracy, 30 ppm/°C temperature coefficient, and ≤75 μA supply current in SOT23-5 package. It operates from −40°C to +85°C, supports up to 20 mA load, and enables high-accuracy analog signal conditioning in space-constrained battery-powered systems.
For engineers reviewing the LM4130EIM5-2.5/NOPB datasheet, LM4130EIM5-2.5/NOPB pinout, LM4130EIM5-2.5/NOPB application, or LM4130EIM5-2.5/NOPB equivalent, key selection criteria include dropout voltage (≤275 mV @ 10 mA), capacitive load stability (0–100 µF), output impedance (<1 Ω), and grade-specific tempco/accuracy trade-offs across A–E variants.
Technical Context
The LM4130EIM5-2.5/NOPB uses EEPROM-trimmed CMOS bandgap architecture to correct curvature, tempco, and initial accuracy at package level-overcoming assembly-induced shifts that limit laser-trimmed bipolar references. Its LDO topology eliminates need for output buffer or mandatory output capacitor, unlike conventional series references.
Pin configuration includes dedicated VIN (Pin 4), VREF (Pin 5), Ground (Pin 2), and two NC pins (Pins 1 & 3). Line regulation is 150 ppm/V over VREF + 400 mV to 5.5 V, and load regulation is 80 ppm/mA across 0–20 mA, enabling stable operation under dynamic load conditions without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500 V ±0.5% - ensures precise ADC/DAC biasing and sensor excitation within 12.5 mV absolute error at 25°C |
| Tempco | 30 ppm/°C - limits drift to ±2.55 mV over −40°C to +85°C operating range |
| Dropout Voltage | ≤275 mV @ 10 mA - allows operation from 2.775 V input, critical for single-cell Li-ion or 3.3 V rail margin |
| Supply Current | ≤75 μA - enables multi-year battery life in always-on instrumentation and portable sensors |
| Load Capability | 20 mA - supports direct driving of op-amp inputs, SAR ADC references, and small logic loads without buffering |
| Capacitive Load Stability | 0–100 µF - permits use of bulk ceramic or tantalum output caps for transient suppression without oscillation |
| Noise (0.1–10 Hz) | 150 μVPP - suitable for 16-bit+ data acquisition where reference noise dominates system ENOB |
Pinout & Package
SOT23-5 surface-mount package with 1.6 mm × 2.9 mm footprint, 0.95 mm height, and gull-wing leads. Thermal resistance θJ-A = 220°C/W; max power dissipation = 350 mW at 25°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | No Connection (NC) | Internally terminated; must remain unconnected to avoid parasitic coupling or mechanical stress |
| Pin 2 | Ground | Primary return path for reference output and supply current; requires low-impedance PCB connection |
| Pin 3 | No Connection (NC) | Internally terminated; floating connection prevents unintended feedback or ESD path |
| Pin 4 | VIN | Positive supply input; bypass with 0.1 µF capacitor recommended for noisy or dynamically loaded rails |
| Pin 5 | VREF | Stable 2.500 V output; sources up to 20 mA; stable with 0–100 µF capacitive loads; no buffer required |
Key Features
| Feature | Design Value |
|---|---|
| EEPROM-based trimming | Enables post-assembly correction of tempco and accuracy in plastic SOT23-5, eliminating laser-trimming cost and yield loss |
| No output capacitor required | Reduces BOM count and board area vs. shunt or buffered series references; simplifies layout in ultra-compact designs |
| Low dropout voltage | 275 mV @ 10 mA allows operation from 2.775 V input-critical for single-supply 3 V systems with tight headroom |
| Full-grade specification | E-grade (±0.5%, 30 ppm/°C) provides cost-optimized accuracy for industrial sensing and non-critical measurement |
| Extended temperature operation | Rated for −40°C to +85°C with guaranteed specs; thermal hysteresis ≤50 ppm ensures repeatability after thermal cycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C25IDBZR | Shunt reference; 2.5 V, ±0.5%, 100 ppm/°C; requires external cathode resistor; 60 μA typical IQ | Higher tempco and fixed 2.5 V output only; suited for low-cost, low-current biasing where dropout is irrelevant | Select when board space allows resistor placement and load current is <1 mA; not drop-in due to topology difference |
| REF3025AIDBZR | Series reference; 2.5 V, ±0.2%, 50 ppm/°C; 50 μA IQ; requires 1 µF min output cap; 125 mV dropout @ 10 mA | Better accuracy/tempco but higher minimum capacitance requirement; lower dropout enables tighter supply margins | Choose for higher-precision designs needing <±0.2% accuracy; not pin-compatible-different pinout and biasing scheme |
Compared with LM4130EIM5-2.5/NOPB, LM4040C25IDBZR offers lower quiescent current but demands external resistor and lacks LDO capability, while REF3025AIDBZR delivers superior accuracy and lower dropout but mandates output capacitance and uses incompatible pin mapping.

FAQ
What is the operating temperature range for LM4130EIM5-2.5/NOPB?
The LM4130EIM5-2.5/NOPB is specified for full performance across −40°C to +85°C. Electrical characteristics-including output voltage accuracy, tempco, and dropout-are ensured over this range per the SNVS048D datasheet. Extended operation to +125°C is possible but not fully characterized for all parameters.
Does LM4130EIM5-2.5/NOPB require an output capacitor?
No, the LM4130EIM5-2.5/NOPB is designed to operate stably without any output capacitor and remains stable with capacitive loads from 0 to 100 µF. Adding a capacitor improves load transient response but is optional-not required for basic functionality or stability.
What does the 'E' grade indicate in LM4130EIM5-2.5/NOPB?
The 'E' in LM4130EIM5-2.5/NOPB denotes the E-grade variant: ±0.5% initial output voltage accuracy and 30 ppm/°C temperature coefficient over −40°C to +85°C. This grade balances cost and performance for industrial and commercial applications where ultra-high precision is not required.
Can LM4130EIM5-2.5/NOPB drive a 20 mA load continuously?
Yes, the LM4130EIM5-2.5/NOPB is rated to source up to 20 mA continuously. At 10 mA load, dropout is ≤275 mV; at full 20 mA, thermal considerations and PCB copper area must ensure junction temperature stays below 125°C, given its 220°C/W θJ-A.
Is LM4130EIM5-2.5/NOPB pin-compatible with other LM4130 variants?
Yes, all LM4130 variants-including LM4130A/B/C/D/E in 2.5 V and 4.096 V versions-share identical SOT23-5 pinout (VIN, GND, NC, NC, VREF). The 'E' grade differs only in trimmed accuracy and tempco; electrical interface and PCB footprint are fully interchangeable.
