Product details
Overview
LM136H-5.0/NOPB from Texas Instruments is a precision 5.0V shunt voltage reference diode in a TO-metal-can package, rated for −55°C to +125°C operation, with ±1% initial tolerance, 0.6Ω dynamic impedance, and 600 μA to 10 mA operating current range. It serves as a stable low-voltage reference in digital voltmeters, precision power supplies, and op amp biasing circuits.
For engineers reviewing the LM136H-5.0/NOPB datasheet, LM136H-5.0/NOPB pinout, LM136H-5.0/NOPB application, or LM136H-5.0/NOPB equivalent, key selection considerations include temperature stability over extended industrial/military ranges, trimmable voltage/temperature coefficient, and compatibility with both positive and negative reference configurations.
Technical Context
The LM136H-5.0/NOPB functions as a monolithic shunt regulator with zener-like behavior but achieves 0.6Ω dynamic impedance and low temperature coefficient via internal bandgap-derived architecture. Its three-terminal configuration enables external adjustment of both output voltage (±1V typical) and temperature drift using external resistors or diodes.
Unlike standard zeners, it delivers specified temperature stability across its full operating range (−55°C to +125°C), with breakdown voltage change limited to 20–36 mV over that span. The third terminal provides direct access to the internal reference node, allowing independent trimming of voltage and temperature coefficient without interaction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reference Voltage | 5.00 V nominal at 1 mA; tight 4.9–5.1 V min/max range ensures accurate system-level calibration. |
| Initial Tolerance | ±1% at 25°C; reduces need for post-assembly trimming in production test flows. |
| Operating Current | 600 μA to 10 mA; supports low-power sensor interfaces and high-current buffer stages without external amplification. |
| Dynamic Impedance | 0.6 Ω typical; maintains stable output under varying load or supply ripple, critical for ADC reference and feedback loops. |
| Temp Range | −55°C to +125°C; qualified for aerospace, downhole, and military-grade embedded systems requiring extended thermal resilience. |
| Temp Stability | 20–36 mV max deviation from 25°C; enables predictable performance in unregulated environments without active compensation. |
| Adjustment Range | ±1.0 V typical via external potentiometer; allows correction of board-level tolerances and aging drift in long-life applications. |
Pinout & Package
LM136H-5.0/NOPB uses a hermetically sealed TO-metal-can (NDV) package with 3 leads and 2.67 mm maximum height, optimized for high-reliability, high-temperature, and low-noise analog applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current sink terminal | Connects to ground or negative rail; defines reference polarity when used as negative reference. |
| Cathode (Pin 2) | Output/reference terminal | Provides regulated 5.0V output; connects to load or feedback network; voltage measured between Cathode and Anode. |
| Adjust (Pin 3) | Trim control node | Enables external adjustment of reference voltage and temperature coefficient; tied to internal bandgap node for precise calibration. |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 0.6 Ω ensures minimal output voltage shift under load transients-critical for high-resolution data acquisition. |
| Wide operating current | 600 μA–10 mA accommodates ultra-low-power IoT sensors and high-current reference buffers without redesign. |
| Three-terminal adjustability | Independent trimming of voltage and temperature coefficient avoids trade-offs between accuracy and thermal drift. |
| Hermetic metal-can package | TO-NDV construction provides superior moisture resistance, long-term stability, and EMI shielding vs. plastic packages. |
| Fast turn-on response | Enables use in power-on-reset circuits and dynamically switched reference rails without settling delay penalties. |

FAQ
What is the maximum operating temperature for LM136H-5.0/NOPB?
The LM136H-5.0/NOPB is rated for continuous operation from −55°C to +125°C ambient temperature, with junction temperature limited to 150°C. This specification is validated per TI's thermal characterization data and makes LM136H-5.0/NOPB suitable for under-hood automotive, downhole, and military applications where plastic-packaged alternatives fail.
Can LM136H-5.0/NOPB be used as a negative voltage reference?
Yes, LM136H-5.0/NOPB can function as either a positive or negative voltage reference because it operates as a shunt regulator. When the anode is tied to a positive rail and cathode to ground, it establishes a stable −5.0V reference at the anode. This dual-polarity capability simplifies bipolar supply designs and eliminates need for separate negative references in LM136H-5.0/NOPB-based systems.
How is the temperature coefficient trimmed on LM136H-5.0/NOPB?
The LM136H-5.0/NOPB features a dedicated Adjust (Pin 3) terminal that connects directly to its internal bandgap node. By adding a diode network (e.g., four 1N4148 diodes) in series with a potentiometer between Pin 3 and cathode-as shown in Figure 15 of the datasheet-the temperature coefficient is minimized when the output is adjusted precisely to 5.00V. This method decouples voltage setting from thermal drift optimization.
What is the minimum operating current for LM136H-5.0/NOPB to maintain regulation?
The LM136H-5.0/NOPB requires a minimum reverse current of 600 μA to maintain regulation within specifications. Below this threshold, output voltage deviates from 5.00V and dynamic impedance rises significantly. Designers must ensure bias networks or load paths guarantee ≥600 μA total current through LM136H-5.0/NOPB under all operating conditions, including sleep modes.
Is LM136H-5.0/NOPB RoHS compliant?
Yes, LM136H-5.0/NOPB is RoHS compliant, as confirmed by TI's Package Option Addendum: the "/NOPB" suffix denotes lead-free finish, and the part carries "Yes" in the RoHS column. It meets EU Directive 2011/65/EU requirements and is suitable for environmentally regulated commercial and industrial end equipment.
