Product details
Overview
LM4132BMF-3.0/NOPB from Texas Instruments is a precision low-dropout (LDO) series voltage reference IC delivering a stable 3.0 V output with 0.1% initial accuracy, 10 ppm/°C temperature coefficient (0°C to 85°C), and 60 µA quiescent current. It features an enable pin for 3 µA shutdown mode, supports up to 20 mA load current, and operates from VIN = VREF + 400 mV to 5.5 V - ideal for high-accuracy ADC/DAC biasing in portable instrumentation.
For engineers reviewing the LM4132BMF-3.0/NOPB datasheet, LM4132BMF-3.0/NOPB pinout, LM4132BMF-3.0/NOPB application, or LM4132BMF-3.0/NOPB equivalent, key selection criteria include its SOT-23-5 package, dropout voltage of 175 mV at 10 mA, line regulation of 70 ppm/V, and automotive-grade qualification (AEC-Q100 Grade B, –40°C to +125°C).
Technical Context
The LM4132BMF-3.0/NOPB uses EEPROM-trimmed CMOS bandgap architecture to achieve laser-trimmed bipolar-level precision without requiring external output capacitance or buffer amplifiers. Its curvature correction and tempco compensation are programmed at package level to mitigate assembly-induced shifts.
This device operates as a three-terminal series reference with active enable control, supporting direct connection to precision analog signal chains. Its 400 mV maximum dropout and 20 mA output capability enable use in low-voltage, space-constrained systems where shunt references would waste power.

FAQ
What is the operating temperature range for the LM4132BMF-3.0/NOPB?
The LM4132BMF-3.0/NOPB is rated for –40°C to +125°C ambient operating temperature and is AEC-Q100 Grade B qualified. Its temperature coefficient is specified at 10 ppm/°C from 0°C to 85°C and 20 ppm/°C across the full –40°C to +125°C range, ensuring predictable performance in automotive and industrial environments.
Does the LM4132BMF-3.0/NOPB require an output capacitor?
No, the LM4132BMF-3.0/NOPB is internally compensated and stable without an output capacitor. A 0.1 µF ceramic capacitor (COUT) is optional and improves transient response but is not required for stability - simplifying layout and reducing BOM count in space-constrained designs.
What is the minimum input voltage required for regulation of the LM4132BMF-3.0/NOPB?
The LM4132BMF-3.0/NOPB requires a minimum input voltage of VREF + 400 mV, i.e., 3.4 V, to maintain regulation at full load. At 10 mA load, its typical dropout is 175 mV, allowing reliable operation down to 3.175 V input while maintaining 3.0 V output within specification.
How does the enable pin function on the LM4132BMF-3.0/NOPB?
The EN pin on the LM4132BMF-3.0/NOPB is an active-high digital control: VIH ≥65% of VIN enables the reference (60 µA IQ), while VIL ≤35% of VIN places it in shutdown (≤3 µA IQ). No external pull-up/down is required; the pin has no internal bias and must be driven actively.
Is the LM4132BMF-3.0/NOPB compatible with standard SOT-23-5 footprints?
Yes, the LM4132BMF-3.0/NOPB uses the industry-standard DBV (SOT-23-5) package with 2.90 mm × 1.60 mm body dimensions and 0.95 mm height. Its pinout (N/C, GND, EN, VIN, VREF) matches JEDEC MO-178AB, enabling drop-in compatibility with existing SOT-23-5 layouts and reflow profiles.
