Product details
Overview
LM4130BIM5-2.5/NOPB from Texas Instruments is a precision micropower low-dropout voltage reference IC delivering 2.500 V output with ±0.2% initial accuracy, 10 ppm/°C temperature coefficient (−40°C to +85°C), and ≤275 mV dropout at 10 mA load - used as a stable reference in high-resolution ADCs, portable instrumentation, and battery-powered sensor signal chains.
For engineers reviewing the LM4130BIM5-2.5/NOPB datasheet, LM4130BIM5-2.5/NOPB pinout, LM4130BIM5-2.5/NOPB application, or LM4130BIM5-2.5/NOPB equivalent, key selection criteria include guaranteed tempco over full industrial temperature range, capacitive-load stability up to 100 µF without external buffer, and ultra-low 75 µA supply current enabling multi-year operation on coin cells.
Technical Context
The LM4130BIM5-2.5/NOPB implements a CMOS bandgap architecture with EEPROM-based curvature, tempco, and accuracy correction - enabling laser-trim-level performance in plastic SOT23-5 packaging. Its internal trimming compensates for assembly-induced voltage shift, ensuring specified ±0.2% accuracy and 10 ppm/°C tempco are met post-packaging.
Unlike shunt references, it operates as a series reference with no minimum load requirement and zero mandatory output capacitance. It maintains <1 Ω output impedance and stable regulation across 0–20 mA load, 2.775–5.5 V input (VREF + 275 mV min), and −40°C to +85°C ambient - with extended operation validated to +125°C.

FAQ
What is the guaranteed temperature coefficient of LM4130BIM5-2.5/NOPB over −40°C to +85°C?
The LM4130BIM5-2.5/NOPB has a guaranteed temperature coefficient of 20 ppm/°C over the full −40°C to +85°C operating range. Its datasheet specifies 10 ppm/°C maximum over 0°C to +85°C, but the wider industrial range is rated at 20 ppm/°C - a value confirmed in Table 1 of the SNVS048D datasheet for LM4130B grade devices. This ensures predictable drift in outdoor or factory-floor deployments.
Does LM4130BIM5-2.5/NOPB require an output capacitor for stability?
No, the LM4130BIM5-2.5/NOPB is explicitly designed to operate stably with 0 µF output capacitance and remains stable with capacitive loads up to 100 µF. This eliminates mandatory external capacitors in space-constrained layouts. An optional output capacitor improves load transient response but increases turn-on time - a trade-off documented in the Application Information section of the LM4130BIM5-2.5/NOPB datasheet.
What is the maximum load current supported by LM4130BIM5-2.5/NOPB while maintaining regulation?
The LM4130BIM5-2.5/NOPB supports up to 20 mA of continuous output current while maintaining regulation and specified accuracy. Its output stage is designed to source this full current without external buffering, and load regulation is characterized from 0 mA to 20 mA in the Electrical Characteristics table - confirming <60 ppm/mA shift across the entire range.
Can LM4130BIM5-2.5/NOPB be used in applications requiring operation beyond +85°C?
Yes, the LM4130BIM5-2.5/NOPB is specified for extended operation up to +125°C, though full accuracy (±0.2%, 20 ppm/°C) is only ensured from −40°C to +85°C. At +125°C, parameters like tempco and long-term stability may degrade - thermal hysteresis is tested across −40°C to +125°C, confirming repeatability, but users must validate system-level performance at elevated temperatures per their design requirements.
What do the 'B' and 'M5' in LM4130BIM5-2.5/NOPB signify?
In LM4130BIM5-2.5/NOPB, 'B' denotes the initial accuracy grade (±0.2% and 10 ppm/°C over 0°C to +85°C), 'I' indicates the industrial temperature range (−40°C to +85°C), 'M5' specifies the SOT23-5 package, and '/NOPB' confirms lead-free, RoHS-compliant finish. This full designation maps directly to TI's ordering guide and marking table in the SNVS048D datasheet.
