Product details
Overview
LM9036MM-3.3 from Texas Instruments is a fixed-output 3.3V, 50mA ultra-low quiescent current linear voltage regulator in an 8-pin VSSOP package. It features ≤25µA ground pin current at 0.1mA load, 200mV typical dropout at full load, ±5% output tolerance over line/load/temperature, and −45V reverse transient protection - designed for automotive battery-supplied systems requiring extended standby life.
For engineers reviewing the LM9036MM-3.3 datasheet, LM9036MM-3.3 pinout, LM9036MM-3.3 application, or LM9036MM-3.3 equivalent, key selection considerations include its 40V maximum operating voltage, thermal shutdown at 150°C, internal short-circuit limiting, and compatibility with low-ESR output capacitors (22–33µF, 0.3–8Ω).
Technical Context
The LM9036MM-3.3 uses a PNP pass transistor architecture enabling low dropout operation while maintaining regulation up to 40V input. Its internal circuitry integrates reverse-battery protection, thermal shutdown, and current limiting without external components.
It operates across −40°C to +125°C ambient, supports stable regulation with 22–33µF output capacitance (0.3–8Ω ESR), and exhibits −40dB to −60dB ripple rejection at 120Hz - critical for noise-sensitive automotive microcontroller power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±5% over full line, load, and temperature range - ensures reliable MCU core/logic supply under varying battery conditions. |
| Max Output Current | 50mA continuous - sufficient for low-power microcontrollers, sensors, and CAN transceivers in always-on modules. |
| Quiescent Current | ≤25µA at 0.1mA load - enables >10-year battery life in vehicle telematics or remote keyless entry systems. |
| Dropout Voltage | 200mV typical at 50mA - allows regulation down to ~3.5V input, supporting operation during cold-crank (6–8V) events. |
| Reverse Transient Protection | −45V survival rating - withstands load-dump transients per ISO 7637-2 Pulse 5a without external clamping. |
| Operating Voltage Range | Up to 40V DC input - accommodates 24V commercial vehicle systems and 12V automotive with margin. |
| Thermal Shutdown | Activates at ~150°C junction temperature - protects against sustained overload or poor PCB heatsinking. |
Pinout & Package
VSSOP-8 (DGK) package: 3.0mm × 3.0mm body, 1.1mm max height, exposed thermal pad, 0.65mm pitch. Pin 1 index area located at top-left corner per JEDEC MO-187.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 4.5V–40V DC; connects to bulk capacitor near regulator input. |
| 2 (GND) | Ground reference | Low-impedance return path; ties to exposed thermal pad for thermal conduction. |
| 3 (OUT) | Regulated output | Delivers stable 3.3V; requires 22–33µF low-ESR capacitor placed adjacent to pin. |
| 4 (GND) | Ground reference | Second ground terminal improves PSRR and reduces ground bounce in noisy environments. |
| 5 (GND) | Ground reference | Third ground terminal enhances thermal dissipation via exposed pad connection. |
| 6 (GND) | Ground reference | Fourth ground terminal supports low-noise layout for sensitive analog peripherals. |
| 7 (GND) | Ground reference | Fifth ground terminal minimizes voltage drop across PCB traces under dynamic load. |
| 8 (GND) | Ground reference | Sixth ground terminal provides robust grounding for EMI suppression in automotive harnesses. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ground pin current | ≤25µA at 0.1mA load - extends battery runtime in always-on vehicle modules like door controllers. |
| Integrated reverse-battery protection | Withstands −45V transients - eliminates need for external series diode or TVS in 12V battery interfaces. |
| Thermal shutdown with hysteresis | Triggers at ~150°C junction, resets ~20°C below - prevents thermal runaway during sustained overload. |
| Short-circuit current limit | 65–250mA foldback - protects regulator and upstream fuse during wiring faults without latch-up. |
| Stable with ceramic output capacitors | Validated for 22–33µF, 0.3–8Ω ESR - enables compact, high-reliability designs without tantalum or electrolytic parts. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLD1113-33 | Higher IQ (45µA), 150mA output, integrated enable pin - no reverse-battery protection. | Requires external TVS for −45V transients; better suited for non-automotive industrial use. | Select when higher output current and enable control outweigh reverse-protection needs. |
| TPS7B6733QDCYRQ1 | Lower IQ (15µA), 200mA output, AEC-Q100 qualified, integrated reset - same 40V max input. | Includes power-good flag and tighter initial accuracy (±1.5%), but larger SOIC-8 footprint. | Prefer for new AEC-Q100-compliant designs requiring diagnostics and higher current headroom. |
Compared with TLD1113-33 and TPS7B6733QDCYRQ1, the LM9036MM-3.3 offers unique reverse-battery protection in a space-constrained VSSOP-8 package - making it optimal for legacy automotive modules where board real estate and transient robustness are prioritized over enable functionality or AEC-Q100 certification.

FAQ
What is the maximum input voltage for the LM9036MM-3.3?
The LM9036MM-3.3 has a maximum operational input voltage of 40V DC. While it can survive transient inputs up to +55V and −45V, continuous operation above 40V violates its absolute maximum rating and may cause permanent damage. This 40V limit ensures safe operation in 24V commercial vehicle systems and 12V automotive systems with load-dump margins.
Does the LM9036MM-3.3 require an external capacitor for stability?
Yes, the LM9036MM-3.3 requires a minimum 22µF output capacitor with ESR between 0.3Ω and 8Ω for stability. The datasheet specifies 22–33µF ceramic or tantalum types; placement must be within 5mm of the OUT and GND pins. No input capacitor is mandatory, but a 1µF ceramic is recommended if the input trace exceeds 2 inches from the bulk filter.
What is the thermal performance of the LM9036MM-3.3 in its VSSOP-8 package?
In the VSSOP-8 (DGK) package, the LM9036MM-3.3 has a junction-to-ambient thermal resistance (θJA) of 200°C/W in free air. With a 1-inch² 2oz copper thermal pad under the exposed ground pad, θJA improves to ~50°C/W. At 50mA load and 85°C ambient, this allows ~29.5V max input before thermal shutdown - verified in TI's application notes.
Can the LM9036MM-3.3 replace the LM9036M-3.3 in an existing SOIC-8 design?
No, the LM9036MM-3.3 cannot be used as a direct replacement for the LM9036M-3.3 without PCB redesign. Although both deliver identical electrical performance, the LM9036MM-3.3 uses an 8-pin VSSOP package (3.0mm × 3.0mm, 0.65mm pitch), whereas the LM9036M-3.3 uses an 8-pin SOIC package (3.9mm × 4.9mm, 1.27mm pitch). Footprint and solder stencil are incompatible.
What protection features are built into the LM9036MM-3.3?
The LM9036MM-3.3 integrates four key protections: (1) reverse-battery protection up to −45V, (2) internal short-circuit current limiting (65–250mA), (3) thermal shutdown at ~150°C junction temperature, and (4) safe operating area (SOA) protection limiting power dissipation. These functions operate autonomously without external components - critical for automotive reliability.
