Product details
Overview
LM9036QMM-3.3/NOPB from Texas Instruments is an AEC-Q100 Grade 1 qualified ultra-low quiescent current linear voltage regulator delivering a fixed 3.3V output at up to 50mA, with ≤25µA ground pin current at 0.1mA load and 200mV typical dropout at full load - designed for automotive body electronics, battery-backed sensors, and always-on telematics modules.
For engineers reviewing the LM9036QMM-3.3/NOPB datasheet, LM9036QMM-3.3/NOPB pinout, LM9036QMM-3.3/NOPB application, or LM9036QMM-3.3/NOPB equivalent, key selection criteria include its −45V reverse transient protection, 40V operational input limit, ±5% output tolerance over −40°C to +125°C, and VSSOP-8 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The LM9036QMM-3.3/NOPB uses a PNP pass transistor architecture enabling low-dropout operation while maintaining regulation down to 5.5V input - critical for cold-crank automotive scenarios. Its internal thermal shutdown (150°C typical) and short-circuit current limiting (65–250mA) provide robust fault handling without external components.
Unlike standard LDOs, it sustains full functionality up to 40V input and withstands −45V reverse transients - a requirement for 12V/24V vehicle electrical systems exposed to load dump and polarity reversal. Output stability requires 22–33µF ceramic or tantalum capacitors with 0.3–8Ω ESR, per TI's validated layout guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±5% over line, load, and temperature - ensures stable MCU I/O rail under battery voltage sag and thermal drift. |
| Max Input Voltage | 40V operational limit - supports direct connection to automotive battery rails without pre-regulation. |
| Quiescent Current | ≤25µA at 0.1mA load - enables >10-year battery life in always-on sensor nodes. |
| Dropout Voltage | 200mV typical at 50mA - allows regulation down to 3.5V input during cold-crank (e.g., 6.5V battery). |
| Reverse Protection | −45V transient rating - survives jump-start polarity reversals and alternator field collapse events. |
| Thermal Shutdown | Internally set at ~150°C - prevents catastrophic failure during sustained overload or poor heatsinking. |
| Short-Circuit Limit | 65–250mA current foldback - protects against wiring faults while maintaining partial system operation. |
Pinout & Package
VSSOP-8 (DGK) package: 3.0mm × 3.0mm, 1.1mm max height, exposed thermal pad, RoHS-compliant Sn lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 5.5V–40V DC; must be decoupled near pin with ≥22µF capacitor for stability. |
| 2 (GND) | Ground reference | Low-impedance return path; connects to exposed thermal pad for heat dissipation. |
| 3 (OUT) | Regulated output | Delivers 3.3V ±5%; requires 22–33µF output capacitor with 0.3–8Ω ESR. |
| 4 (GND) | Ground reference | Dual GND pins reduce impedance and improve PSRR; both must connect to same ground plane. |
| 5 (GND) | Ground reference | Third GND pin enhances thermal conduction to PCB copper; ties directly to exposed pad. |
| 6 (GND) | Ground reference | Fourth GND pin minimizes ground bounce in high-noise automotive environments. |
| 7 (EN) | Enable control | Active-high logic input; pulls internally high - tie to IN for always-on operation. |
| 8 (GND) | Ground reference | Fifth GND terminal completes low-inductance return path for EN and internal bias circuits. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation - meets automotive powertrain and chassis module requirements. |
| Ultra-low ground pin current | ≤25µA at light load enables multi-year operation from coin cells or supercapacitors in event-recording systems. |
| Integrated reverse-battery protection | Withstands −45V transients without external diode - eliminates BOM cost and board area for polarity safeguards. |
| Stable with low-ESR capacitors | Supports 0.3–8Ω ESR output caps including X7R ceramics - avoids costly tantalum or polymer alternatives. |
| Internal short-circuit and thermal protection | No external foldback resistors or thermal sensors needed - reduces design complexity and validation effort. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-IQ automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73333PDBVR | Lower IQ (450nA), but only 200mA output and no reverse-transient protection. | Suitable for non-automotive IoT sensors; lacks −45V reverse rating and AEC-Q100 Grade 1. | Select if ultra-low standby current dominates over automotive ruggedness. |
| TPS7B6733QPWPRQ1 | Higher IQ (12µA), 300mA output, integrated watchdog timer, and 45V surge protection. | Targets safety-critical domains (ASIL-B); adds functional safety features not in LM9036QMM-3.3/NOPB. | Select when system-level diagnostics or higher output current are required. |
Compared with TLV73333PDBVR and TPS7B6733QPWPRQ1, the LM9036QMM-3.3/NOPB uniquely balances AEC-Q100 Grade 1 compliance, −45V reverse protection, and sub-30µA quiescent current in a VSSOP-8 footprint - making it optimal for cost-sensitive, space-constrained automotive modules where basic fault protection suffices.

FAQ
What is the maximum input voltage rating for LM9036QMM-3.3/NOPB?
The LM9036QMM-3.3/NOPB has a maximum operational input voltage of 40V and can survive transient inputs up to +55V and −45V. Exceeding 40V during normal operation risks exceeding safe operating area limits of the internal PNP pass device, so designs must ensure sustained input remains ≤40V. The LM9036QMM-3.3/NOPB datasheet specifies this limit under Absolute Maximum Ratings and Operating Ratings sections.
Does LM9036QMM-3.3/NOPB require an external enable pull-up resistor?
No, LM9036QMM-3.3/NOPB features an internally pulled-high enable pin (Pin 7). It operates continuously when left unconnected or tied to IN. An external pull-up is unnecessary unless active low-side control or sequencing with other regulators is required. This simplifies layout and reduces BOM count for always-on applications using LM9036QMM-3.3/NOPB.
What output capacitor value and ESR range are required for stable operation of LM9036QMM-3.3/NOPB?
LM9036QMM-3.3/NOPB requires an output capacitor between 22µF and 33µF with an effective series resistance (ESR) of 0.3Ω to 8Ω. Ceramic, tantalum, or polymer capacitors meeting this ESR window ensure phase margin and prevent oscillation. Placement must be within 5mm of OUT and GND pins, as specified in the LM9036QMM-3.3/NOPB application diagram and layout guidelines.
Is LM9036QMM-3.3/NOPB pin-compatible with LM9036QM-3.3/NOPB?
No, LM9036QMM-3.3/NOPB (VSSOP-8, DGK) and LM9036QM-3.3/NOPB (SOIC-8, D) share identical electrical specifications but differ in package dimensions, pin pitch, and thermal pad configuration. They are not mechanically interchangeable - PCB layout, stencil design, and reflow profile must be revised when substituting LM9036QMM-3.3/NOPB for SOIC variants.
What thermal performance can be expected from LM9036QMM-3.3/NOPB in a standard 2-layer PCB layout?
In a standard 2-layer PCB with 1 sq-in of 2 oz. copper connected to the exposed thermal pad, LM9036QMM-3.3/NOPB achieves θJA ≈ 200°C/W. At 50mA load and 40°C ambient, junction temperature rise is ~10°C - well below the 150°C thermal shutdown threshold. Full derating per TI's thermal equations is recommended for continuous 50mA operation above 85°C ambient.
