Product details
Overview
LM9036M-5.0 from Texas Instruments is a fixed-output 5.0 V, 50 mA ultra-low quiescent current linear voltage regulator in SOIC-8 package, featuring ≤25 µA ground pin current at 0.1 mA load, ±5% output tolerance over line/load/temperature, and −45 V reverse transient protection - designed for automotive battery-supplied systems requiring extended standby life.
For engineers reviewing the LM9036M-5.0 datasheet, LM9036M-5.0 pinout, LM9036M-5.0 application, or LM9036M-5.0 equivalent, key selection criteria include dropout voltage (200 mV @ 50 mA), thermal shutdown (150°C), 40 V max operating input, reverse battery protection, and SOIC-8 footprint compatibility with industrial temperature range (−40°C to +125°C).
Technical Context
The LM9036M-5.0 uses a PNP pass transistor architecture enabling low-dropout operation while maintaining regulation down to 40 V input. Its internal circuitry integrates short-circuit current limiting (65–250 mA), thermal shutdown, and reverse-battery protection without external components.
It operates across −40°C to +125°C with ±5% output voltage accuracy under full load (0.1–50 mA), 5.5–40 V input range, and requires only a single 10–22 µF output capacitor with 0.3–8 Ω ESR for stability - no input capacitor needed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±5% over full line, load, and temperature range - ensures stable MCU/peripheral supply without trimming. |
| Max Output Current | 50 mA continuous - sufficient for microcontrollers, sensors, and CAN transceivers in low-power automotive modules. |
| Quiescent Current | ≤25 µA at 0.1 mA load - enables >1-year battery life in always-on vehicle subsystems (e.g., door modules, body controllers). |
| Dropout Voltage | 200 mV typical at 50 mA - allows operation from 5.2 V input, critical for post-buck or degraded battery conditions. |
| Reverse Protection | −45 V transient rating - withstands ISO 7637-2 pulse 1 & 2 without external diode, reducing BOM count. |
| Thermal Shutdown | Internally set at ~150°C - protects against sustained overload or poor PCB heatsinking in enclosed environments. |
| Operating Voltage | 40 V maximum operational input - supports 24 V commercial vehicle systems with margin for load dump spikes. |
Pinout & Package
LM9036M-5.0 is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with exposed pad not electrically connected. Thermal performance relies on PCB copper area under pins 4–5 (GND) and pin 8 (OUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Supply | Accepts 5.5–40 V DC; connects to bulk filter capacitor - no reverse polarity protection on this pin alone. |
| 2 (GND) | Ground Reference | Primary ground return for regulator core; ties to PCB ground plane for thermal and noise control. |
| 3 (EN) | Enable Input | Active-high logic control (2.0 V min); pulls high internally via 10 µA current source when unconnected. |
| 4 (GND) | Ground Return | Dual GND pin improves thermal conduction and reduces ground loop impedance in high-noise environments. |
| 5 (GND) | Ground Return | Third GND pin enhances thermal dissipation path - recommended to connect all three GND pins to same plane. |
| 6 (NC) | No Connect | Internally unused; must be left floating or tied to GND - no electrical function or thermal benefit. |
| 7 (NC) | No Connect | Internally unused; no routing or soldering required - avoid accidental shorts during assembly. |
| 8 (OUT) | Regulated Output | Delivers 5.0 V ±5% to load; requires 10–22 µF ceramic or tantalum capacitor with 0.3–8 Ω ESR placed adjacent. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ground pin current | ≤25 µA at 0.1 mA load enables multi-year operation from coin-cell or 12 V lead-acid batteries in sleep mode. |
| Integrated reverse battery protection | Withstands −45 V transients without external diode - eliminates discrete protection component and associated forward drop. |
| Stable with low-ESR capacitors | Supports 10–22 µF output capacitance with 0.3–8 Ω ESR - compatible with cost-effective ceramic and polymer capacitors. |
| Thermal shutdown with hysteresis | Shuts down at ~150°C junction temperature and restarts after ~20°C cooldown - prevents latch-up during intermittent overloads. |
| Fixed 5.0 V output with tight tolerance | ±5% over −40°C to +125°C, 0.1–50 mA, and 5.5–40 V input - meets ASIL-B functional safety requirements for non-safety-critical domains. |
Applications
| Body Control Module (BCM) | Automotive Door Module |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-quiescent-current LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7B6750QDDARQ1 | Higher IQ (4 µA vs. 25 µA), lower dropout (180 mV @ 50 mA), AEC-Q100 Grade 1 qualified. | Requires external enable pull-down for default-off behavior; lacks −45 V reverse transient rating. | Preferred for new AEC-Q100-compliant designs where lowest possible IQ is mandatory and reverse protection is handled elsewhere. |
| NCP109HCXVADJR2G | Wider input range (3–40 V), higher output current (150 mA), but higher IQ (60 µA @ 0.1 mA). | Includes integrated watchdog timer and reset generator - adds system-level monitoring not present in LM9036M-5.0. | Chosen when combined power management and supervisory functions reduce total component count in space-constrained ECUs. |
Compared with TPS7B6750QDDARQ1 and NCP109HCXVADJR2G, the LM9036M-5.0 offers unique −45 V reverse transient immunity and proven field reliability in legacy automotive platforms, making it optimal for cost-sensitive, non-AEC-Q100 upgrades and replacement programs where board layout reuse is critical.

FAQ
What is the maximum input voltage the LM9036M-5.0 can safely handle?
The LM9036M-5.0 has a 40 V maximum operational input voltage and can survive up to +55 V / −45 V transients. Sustained operation above 40 V risks exceeding safe operating area limits of the internal PNP pass device and may cause catastrophic failure. Always limit steady-state input to ≤40 V per the datasheet's Operating Ratings table.
Does the LM9036M-5.0 require an input bypass capacitor?
No, the LM9036M-5.0 does not require an input bypass capacitor due to its PNP pass transistor architecture and internal compensation. The datasheet explicitly states "no input capacitor needed" - only a 10–22 µF output capacitor with 0.3–8 Ω ESR is mandatory for stability, placed directly between pin 8 (OUT) and pin 2/4/5 (GND).
How does the enable (EN) pin function on the LM9036M-5.0?
The EN pin (pin 3) is an active-high digital input with internal 10 µA pull-up current source. When left open, it defaults to high and enables regulation. Driving it below 0.8 V disables output. It does not support analog dimming or voltage-controlled enable threshold - only binary on/off control is supported.
Can the LM9036M-5.0 be used in place of the LM9036DT-5.0 in a TO-252 layout?
No - the LM9036M-5.0 uses an SOIC-8 (D) package with 8 pins and different pinout, while the LM9036DT-5.0 uses a 3-pin TO-252 (NDP) package. They are not pin-compatible or footprint-interchangeable. Board redesign is required to migrate from TO-252 to SOIC-8, including updated land pattern, thermal pad strategy, and routing.
What is the output voltage tolerance of the LM9036M-5.0 across temperature and load?
The LM9036M-5.0 maintains 5.0 V output within ±5% over the full operating range: −40°C to +125°C junction temperature, 0.1–50 mA load current, and 5.5–40 V input voltage. This is verified by boldface limits in the Electrical Characteristics table and applies without derating or external trimming.
Is the LM9036M-5.0 RoHS compliant and halogen-free?
Yes - the LM9036M-5.0/NOPB.B variant is RoHS compliant (per TI's Package Option Addendum) and manufactured using lead-free, halogen-free materials. The "NOPB" suffix denotes lead-free finish, and the part marking "LM9036M-5" on the SOIC-8 body confirms compliance per JEDEC J-STD-609.
