Product details
Overview
LM9036QMMX-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, 200mV typical dropout at full load, and −45V reverse transient protection - designed for automotive body electronics, battery-backed sensors, and always-on telematics modules.
For engineers reviewing the LM9036QMMX-3.3/NOPB datasheet, LM9036QMMX-3.3/NOPB pinout, LM9036QMMX-3.3/NOPB application, or LM9036QMMX-3.3/NOPB equivalent, key selection criteria include its 40V max operating voltage, ±5% output tolerance over line/load/temperature, thermal shutdown behavior, reverse battery protection, and VSSOP-8 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The LM9036QMMX-3.3/NOPB uses a PNP pass transistor architecture enabling low-dropout operation down to 200mV at 50mA while maintaining regulation up to 40V input. Its internal circuitry integrates short-circuit current limiting (120mA typical), thermal shutdown (150°C junction), and reverse-battery protection without external components.
It operates across −40°C to +125°C ambient, meets AEC-Q100 Grade 1 requirements, and sustains stable regulation with 22–33µF output capacitance (0.3–8Ω ESR). The device remains functional during −45V transients but is not rated for continuous operation above 40V input due to SOA limitations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±5% over full line, load, and temperature range - ensures reliable MCU I/O rail compliance in automotive environments. |
| Max Output Current | 50mA - sufficient for powering low-power microcontrollers, CAN transceivers, or sensor signal chains without external boost stages. |
| Quiescent Current | ≤25µA at 0.1mA load - enables >10-year battery life in always-on vehicle modules with coin-cell or supercap backup. |
| Dropout Voltage | 200mV typical at 50mA - allows operation from degraded 5V or 6V battery rails during cold-crank conditions. |
| Input Voltage Range | Operational up to 40V; survives −45V reverse transients - eliminates need for external reverse-polarity diodes in 12V/24V systems. |
| Thermal Protection | Internal shutdown at ~150°C junction - prevents permanent damage during sustained overload or poor heatsinking in sealed enclosures. |
| Package | VSSOP-8 (DGK) with exposed thermal pad - provides 200°C/W θJA for compact layouts; requires PCB copper pour for thermal performance. |
Pinout & Package
VSSOP-8 (DGK0008A) package: 3.0mm × 3.0mm body, 1.1mm max height, 0.65mm pitch, exposed thermal pad on underside for enhanced heat dissipation. Requires solder paste stencil design per TI's recommended aperture dimensions (0.45mm × 1.4mm pads).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 5.5V–40V DC input; must be decoupled near pin with ≥10µF capacitor to suppress transients. |
| 2 (GND) | Ground reference | Low-impedance return path; connects to exposed thermal pad - critical for thermal performance and noise rejection. |
| 3 (OUT) | Regulated output | Delivers stable 3.3V; requires 22–33µF output capacitor with 0.3–8Ω ESR placed within 5mm of pin. |
| 4 (GND) | Ground reference | Dual GND pins reduce impedance; both must be connected to same low-noise ground plane. |
| 5 (GND) | Ground reference | Third GND pin improves PSRR and thermal conduction - ties directly to exposed pad under package. |
| 6 (GND) | Ground reference | Fourth GND pin minimizes ground bounce in high-dI/dt switching loads like CAN drivers. |
| 7 (EN) | Enable control | Active-high logic input; pulls internally high - tie to IN for always-on operation or drive externally for sleep/wake control. |
| 8 (GND) | Ground reference | Fifth GND connection ensures robust grounding across all internal blocks including bandgap and error amplifier. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C operation - meets automotive powertrain and chassis module reliability requirements. |
| Ultra-low ground pin current | ≤25µA at light load - reduces system standby power by >90% vs. standard LDOs, extending battery runtime. |
| Reverse battery protection | Withstands −45V transients without external diode - simplifies front-end protection and saves board space. |
| Integrated short-circuit and thermal protection | Self-limiting current (120mA typ.) and automatic shutdown - eliminates need for external foldback or thermal sensors. |
| Stable with ceramic output capacitors | Compatible with 22–33µF X7R/X5R ceramics (0.3–8Ω ESR) - avoids costly tantalum or aluminum electrolytics. |

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 (350nA), lower max input (6V), no reverse-battery protection, SOT-23-5 package | Suitable only for post-regulated 5V domains; cannot replace LM9036QMMX-3.3/NOPB in direct battery-fed circuits. | Select only if input is pre-regulated and reverse-transient immunity is handled upstream. |
| TPS7B6733QPWPRQ1 | Higher IQ (120µA), wider input (40V), AEC-Q100 Grade 0 (−40°C to +150°C), WSON-6 package | Better thermal performance at high ambient, but higher standby current reduces battery life in always-on nodes. | Prefer when junction temperature exceeds 125°C or when higher output current (250mA) is needed. |
Compared with TLV73333PDBVR and TPS7B6733QPWPRQ1, the LM9036QMMX-3.3/NOPB uniquely balances ultra-low IQ (25µA), 40V operation, reverse-battery protection, and AEC-Q100 Grade 1 - making it the only option for cost-sensitive, space-constrained, battery-direct automotive modules requiring multi-year standby.

FAQ
What is the maximum input voltage rating for LM9036QMMX-3.3/NOPB during normal operation?
The LM9036QMMX-3.3/NOPB has a maximum operational input voltage of 40V. While it can survive −45V reverse transients and up to +55V survival-rated input, continuous operation above 40V violates safe operating area limits and may cause catastrophic failure. Always limit steady-state VIN to ≤40V in designs using LM9036QMMX-3.3/NOPB.
Does LM9036QMMX-3.3/NOPB require an external capacitor on the EN pin for stability?
No, the LM9036QMMX-3.3/NOPB does not require an external capacitor on the EN pin. Its enable input has internal hysteresis and pull-up; adding capacitance may slow turn-on/turn-off timing and is unnecessary for noise immunity. Stability is ensured solely by the output capacitor (22–33µF, 0.3–8Ω ESR), as specified in the LM9036QMMX-3.3/NOPB datasheet.
Can LM9036QMMX-3.3/NOPB be used with ceramic output capacitors?
Yes, the LM9036QMMX-3.3/NOPB is fully compatible with ceramic output capacitors. The datasheet specifies 22–33µF X7R or X5R types with ESR between 0.3Ω and 8Ω. TI's application notes confirm stable operation without oscillation when layout guidelines (short traces, ground plane under exposed pad) are followed for LM9036QMMX-3.3/NOPB.
What is the thermal resistance (θJA) of LM9036QMMX-3.3/NOPB in its VSSOP-8 package?
The LM9036QMMX-3.3/NOPB in VSSOP-8 (DGK) package has a typical junction-to-ambient thermal resistance (θJA) of 200°C/W under standard JEDEC test conditions (1 inch² 2 oz copper). This value assumes no additional thermal vias or heatsinking; actual θJA improves significantly with PCB copper pour connected to the exposed thermal pad beneath LM9036QMMX-3.3/NOPB.
Is LM9036QMMX-3.3/NOPB pin-compatible with other variants in the LM9036Q family?
Yes, all LM9036Q variants - including LM9036QMMX-3.3/NOPB, LM9036QMMX-5.0/NOPB, and LM9036QM-3.3/NOPB - share identical VSSOP-8 (DGK) or SOIC-8 (D) pinouts. The output voltage is factory-set; no external feedback resistors are used. Swapping LM9036QMMX-3.3/NOPB for another variant requires only board-level voltage verification - no layout change is needed.
