Product details
Overview
LM9036QMM-5.0/NOPB from Texas Instruments is an AEC-Q100 Grade 1 qualified ultra-low quiescent current linear voltage regulator delivering a fixed 5.0 V output at up to 50 mA, with ≤25 µA ground pin current at 0.1 mA load, 200 mV typical dropout at full load, and −45 V reverse transient protection - designed for automotive body electronics and battery-powered systems requiring long standby life.
For engineers reviewing the LM9036QMM-5.0/NOPB datasheet, LM9036QMM-5.0/NOPB pinout, LM9036QMM-5.0/NOPB application, or LM9036QMM-5.0/NOPB equivalent, this page provides verified package mapping (VSSOP-8 DGK), thermal performance (θJA = 200°C/W), output tolerance (±5%), reverse battery protection, and PSRR (−60 dB at 120 Hz) - all confirmed for the exact LM9036QMM-5.0/NOPB variant.
Technical Context
The LM9036QMM-5.0/NOPB uses a PNP pass transistor architecture enabling low-dropout operation and inherent reverse-battery protection without external components. It integrates internal short-circuit current limiting (120 mA typical) and thermal shutdown (150°C junction limit), with stable operation requiring only a 10–22 µF output capacitor with 0.3–8 Ω ESR.
Its 40 V maximum operational input voltage and survival rating up to +55 V / −45 V support harsh automotive transients. The device maintains ±5% output regulation across −40°C to +125°C, 5.5–40 V input, and 0.1–50 mA load - validated per AEC-Q100 Grade 1 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±5% over full line/load/temperature range - ensures reliable MCU and sensor biasing in automotive environments. |
| Max Output Current | 50 mA continuous - sufficient for microcontrollers, CAN transceivers, and small logic subsystems in body control modules. |
| Quiescent Current | ≤25 µA at 0.1 mA load - enables >10-year battery standby in always-on vehicle modules (e.g., door modules, keyless entry). |
| Dropout Voltage | 200 mV typical at 50 mA - allows regulation down to VIN = 5.2 V, supporting cold-crank operation where battery dips to 6 V. |
| Reverse Transient Protection | Withstands −45 V transients - eliminates need for external reverse-polarity diode in 12 V automotive systems. |
| PSRR | −60 dB at 120 Hz - suppresses alternator ripple and reduces need for additional filtering in power-sensitive analog circuits. |
| Thermal Shutdown | Activates at ~150°C junction temperature - protects against sustained overload or poor PCB heatsinking without latch-up. |
Pinout & Package
VSSOP-8 (DGK) package: 3.0 mm × 3.0 mm, 1.1 mm 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 5.5–40 V DC; withstands −45 V reverse transients - connects directly to battery rail with no external protection needed. |
| 2 (GND) | Ground reference | Low-impedance return path; ground pin current ≤25 µA at light load - critical for minimizing system standby power. |
| 3 (OUT) | Regulated output | Delivers stable 5.0 V to load; requires 10–22 µF output capacitor with 0.3–8 Ω ESR placed adjacent to pins 2 and 3. |
| 4 (GND) | Ground reference | Dual GND pins reduce IR drop and improve noise rejection - both must be connected to low-impedance ground plane. |
| 5 (GND) | Ground reference | Third GND pin enhances thermal conduction via exposed pad - soldered to PCB thermal pad for θJA = 200°C/W. |
| 6 (GND) | Ground reference | Fourth GND pin further lowers ground impedance - all four GND pins share common internal connection. |
| 7 (GND) | Ground reference | Supports robust grounding for EMI suppression and thermal dissipation - essential for automotive EMC compliance. |
| 8 (GND) | Ground reference | Completes symmetric ground structure; exposed thermal pad (Pin 5) is electrically tied to GND - must be soldered. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C operation - meets automotive under-hood and cabin module reliability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | Lower IQ (350 nA), lower max current (300 mA), but only AEC-Q100 Grade 2 (−40°C to +105°C); no reverse transient rating. | Suitable for cabin modules with less extreme thermal demands; not rated for under-hood use or −45 V transients. | Select if ultra-low IQ dominates over reverse protection and Grade 1 temp range. |
| TPS7B6750QPWPRQ1 | Higher IQ (120 µA), higher dropout (300 mV @ 50 mA), but includes enable pin and adjustable version; AEC-Q100 Grade 1. | Better for designs needing remote ON/OFF control or multiple output voltages; lacks −45 V reverse rating. | Select when system-level enable sequencing or design flexibility outweighs lowest possible IQ and reverse protection. |
Compared with TLV73350PDBVR and TPS7B6750QPWPRQ1, the LM9036QMM-5.0/NOPB uniquely combines Grade 1 temperature rating, −45 V reverse transient immunity, and ≤25 µA IQ - making it the only choice for cost-sensitive, high-reliability body electronics where reverse polarity events and extended temperature operation are non-negotiable.

FAQ
What is the maximum input voltage rating for LM9036QMM-5.0/NOPB?
The LM9036QMM-5.0/NOPB has a maximum operational input voltage of 40 V and a survival rating of +55 V / −45 V. It remains fully functional up to 40 V but will experience catastrophic breakdown above 55 V. Designers must ensure transient clamping or filtering prevents inputs exceeding 55 V, as safe operating area limits prevent short-circuit survival above 40 V. This rating is confirmed in the Absolute Maximum Ratings table of the SNVS685B datasheet.
Does LM9036QMM-5.0/NOPB require an external reverse-polarity protection diode?
No, the LM9036QMM-5.0/NOPB does not require an external reverse-polarity protection diode. Its internal PNP pass transistor architecture provides inherent reverse-battery protection, validated to withstand −45 V transients without damage or latch-up. This capability is explicitly documented in the FEATURES section and APPLICATIONS INFORMATION of the SNVS685B datasheet, eliminating BOM cost and PCB space for discrete protection in automotive 12 V systems.
What output capacitor is required for stable operation of LM9036QMM-5.0/NOPB?
The LM9036QMM-5.0/NOPB requires a 10–22 µF output capacitor with an effective series resistance (ESR) between 0.3 Ω and 8 Ω. Ceramic capacitors meeting these ESR specifications are supported, and the capacitor must be placed as close as possible to the OUT and GND pins. This requirement is specified in the Electrical Characteristics table and Typical Application diagram of the SNVS685B datasheet, and deviation risks instability or oscillation.
Is LM9036QMM-5.0/NOPB qualified for automotive applications?
Yes, the LM9036QMM-5.0/NOPB is AEC-Q100 Grade 1 qualified, certified for operation from −40°C to +125°C ambient temperature. This qualification covers the full electrical specification, thermal performance, and reliability testing required for automotive powertrain, chassis, and body electronics. The Grade 1 status is explicitly stated in the FEATURES section and Operating Ratings table of the SNVS685B datasheet.
What is the thermal resistance (θJA) of LM9036QMM-5.0/NOPB in its VSSOP-8 package?
The LM9036QMM-5.0/NOPB in the VSSOP-8 (DGK) package has a junction-to-ambient thermal resistance (θJA) of 200°C/W under standard JEDEC test conditions (free air). This value assumes proper PCB layout with the exposed thermal pad soldered to a minimum 1-inch² copper area. The θJA is documented in the Operating Ratings table of the SNVS685B datasheet and is critical for calculating maximum allowable power dissipation at elevated ambient temperatures.
