Product details
Overview
LM4130CIM5-2.5/NOPB from Texas Instruments is a precision micropower low-dropout voltage reference IC delivering 2.500 V output with ±0.1% initial accuracy, 20 ppm/°C temperature coefficient, and ≤75 μA supply current in SOT23-5 package. It operates from −40°C to +85°C and supports up to 20 mA load current without requiring an output capacitor - ideal for battery-powered instrumentation and portable data acquisition systems.
For engineers reviewing the LM4130CIM5-2.5/NOPB datasheet, LM4130CIM5-2.5/NOPB pinout, LM4130CIM5-2.5/NOPB application, or LM4130CIM5-2.5/NOPB equivalent, key selection criteria include dropout voltage (≤275 mV @ 10 mA), capacitive load stability (0–100 µF), output impedance (<1 Ω), line/load regulation performance, and grade-specific tempco/accuracy trade-offs across A–E variants.
Technical Context
The LM4130CIM5-2.5/NOPB implements a CMOS bandgap architecture with EEPROM-based curvature, tempco, and accuracy correction - enabling post-assembly calibration to overcome plastic-package-induced shifts. Its LDO topology eliminates need for external buffer amplifiers or mandatory output capacitance.
It features five dedicated pins: VIN (Pin 4), GND (Pin 2), VREF (Pin 5), and two NC terminals (Pins 1 & 3). The device achieves stable operation across 0–100 µF output capacitance and maintains full accuracy over −40°C to +85°C, with extended operation capability to +125°C.

|---|---|---|---|
| REF3025AIDBZR | 2.5 V, ±0.2% initial accuracy, 50 ppm/°C tempco, 50 μA supply current, SOT23-3 | Lower accuracy and higher tempco; lacks NC pins and VIN pin separation | Preferred where lower quiescent current is critical and ±0.2% accuracy suffices |
| ADR3425ARJZ-R7 | 2.5 V, ±0.1% initial accuracy, 10 ppm/°C tempco, 120 μA supply current, SOT23-5 | Superior tempco but higher supply current; requires output capacitor for stability | Selected when tighter thermal drift is required and additional 45 μA current budget is available |

FAQ
Does LM4130CIM5-2.5/NOPB require an output capacitor to maintain stability?
No, LM4130CIM5-2.5/NOPB is explicitly designed to operate stably with 0 µF output capacitance and remains stable up to 100 µF. This eliminates mandatory capacitor placement, reducing BOM count and PCB area - a key advantage over most competing references that require minimum output capacitance for phase margin.
What is the maximum load current supported by LM4130CIM5-2.5/NOPB?
LM4130CIM5-2.5/NOPB can source up to 20 mA continuously while maintaining output voltage regulation within specifications. This capability supports direct driving of ADC reference inputs, op-amp bias networks, and low-power DACs without external buffering.
How does the C-grade specification of LM4130CIM5-2.5/NOPB compare to A- or B-grade variants?
LM4130CIM5-2.5/NOPB provides ±0.1% initial accuracy and 20 ppm/°C temperature coefficient - positioned between A-grade (±0.05%, 10 ppm/°C) and B-grade (±0.2%, 10 ppm/°C). It offers optimal balance of performance and cost for industrial instrumentation where tighter tempco is less critical than absolute initial accuracy.
Can LM4130CIM5-2.5/NOPB operate from a 3.0 V supply?
Yes, LM4130CIM5-2.5/NOPB supports input voltages down to VREF + 275 mV, meaning it functions reliably from a 3.0 V supply (3.0 V − 2.5 V = 500 mV > 275 mV dropout). This enables direct use from common 3.3 V or single-cell Li-ion rails without intermediate regulation.
What is the purpose of Pins 1 and 3 on LM4130CIM5-2.5/NOPB?
Pins 1 and 3 of LM4130CIM5-2.5/NOPB are No Connection (NC) terminals - internally terminated and electrically isolated. They must remain unconnected on the PCB layout to avoid unintended coupling or mechanical stress effects on output voltage accuracy.
