Product details
Overview
LM9036QM-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 and typical dropout voltage of 200 mV at full load - designed for automotive battery-supplied systems requiring long-term standby operation.
For engineers reviewing the LM9036QM-5.0/NOPB datasheet, LM9036QM-5.0/NOPB pinout, LM9036QM-5.0/NOPB application, or LM9036QM-5.0/NOPB equivalent, key selection criteria include its −45 V reverse transient protection, 40 V maximum operating input voltage, ±5% output tolerance over line/load/temperature, and SOIC-8 package compatibility with automotive thermal and reliability requirements.
Technical Context
The LM9036QM-5.0/NOPB uses a PNP pass transistor architecture enabling low-dropout regulation down to 200 mV at 50 mA while maintaining ultra-low ground current - critical for always-on automotive modules. Its internal circuitry integrates reverse-battery protection, thermal shutdown (typically 150°C), and short-circuit current limiting (65–250 mA).
It operates across −40°C to +125°C with 40 V max operational input voltage and survives transients up to −45 V / +55 V. Output stability requires an output capacitor with 0.3–8 Ω ESR (10–22 µF), and it achieves −40 to −60 dB ripple rejection at 120 Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±5% over full line (5.5–40 V), load (0.1–50 mA), and temperature (−40°C to +125°C) range - ensures stable MCU/sensor rail in automotive environments. |
| Quiescent Current | ≤25 µA at 0.1 mA load - enables >10-year battery life in vehicle keep-alive circuits without compromising regulation. |
| Dropout Voltage | 200 mV typical at 50 mA - allows regulation from 5.2 V input, supporting start-stop and cold-crank scenarios. |
| Reverse Transient Protection | Withstands −45 V transients - eliminates need for external reverse-polarity diode in 12 V automotive systems. |
| Thermal Shutdown | Internally activated at ~150°C junction temperature - prevents catastrophic failure during overload or poor heatsinking. |
| Short-Circuit Current Limit | 65–250 mA (typical 120 mA) - provides controlled fault current to avoid trace damage while enabling safe auto-recovery. |
| Ripple Rejection | −40 to −60 dB at 120 Hz - suppresses alternator ripple and improves analog sensor accuracy. |
Pinout & Package
LM9036QM-5.0/NOPB is housed in an 8-pin SOIC (D0008A) package, 3.91 mm × 4.90 mm × 1.75 mm, with exposed pad not electrically connected. Pin 1 is marked by a beveled corner or dot; device orientation follows JEDEC MS-012AA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 5.5–40 V DC input; 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 - minimizes system standby power loss. |
| 3 (OUT) | Regulated output | Delivers stable 5.0 V ±5% to load; requires 10–22 µF output capacitor with 0.3–8 Ω ESR for stability. |
| 4 (GND) | Ground reference | Dual GND pins reduce PCB trace resistance and improve thermal dissipation - critical for sustained 50 mA operation. |
| 5 (GND) | Ground reference | Third GND pin enhances noise immunity and current sharing in high-reliability automotive layouts. |
| 6 (GND) | Ground reference | Fourth GND pin supports low-impedance return for EMI-sensitive applications and improves thermal conduction to PCB copper. |
| 7 (EN) | Enable control | Active-high enable pin; ties internally to IN if unused - allows external microcontroller-controlled power sequencing. |
| 8 (GND) | Ground reference | Fifth GND connection reinforces thermal and electrical integrity; all GND pins must be soldered to ≥1 in² 2 oz copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation - meets automotive engine bay and infotainment module requirements. |
| Ultra-low ground pin current | ≤25 µA at 0.1 mA load - extends battery life in telematics, door modules, and body control units during sleep mode. |
| Integrated reverse-battery protection | No external diode required for −45 V transients - reduces BOM count and PCB area in cost-sensitive automotive designs. |
| Thermal shutdown with hysteresis | Shuts down at ~150°C junction temperature and restarts after cooldown - prevents thermal runaway without external supervision. |
| Stable with ceramic output capacitors | Compatible with 10–22 µF X7R ceramics (0.3–8 Ω ESR) - eliminates tantalum dependency and improves reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-IQ LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLD1114-1EP | Higher IQ (45 µA), 42 V max input, AEC-Q100 Grade 0 (−40°C to +150°C), adjustable output via resistor divider. | Supports higher ambient temperatures but lacks fixed 5.0 V option and reverse transient rating. | Choose when extended temperature range or programmable output is prioritized over lowest quiescent current. |
| TPS7B6750-Q1 | Lower IQ (15 µA), 40 V max input, AEC-Q100 Grade 1, integrated watchdog timer and reset generator. | Includes system-level monitoring features absent in LM9036QM-5.0/NOPB - adds complexity but improves functional safety compliance. | Prefer when ASIL-B diagnostics or power-good signaling are required alongside regulation. |
Compared with TLD1114-1EP and TPS7B6750-Q1, the LM9036QM-5.0/NOPB offers the optimal balance of ultra-low 25 µA quiescent current, fixed 5.0 V output, −45 V reverse protection, and proven SOIC-8 manufacturability - making it ideal for cost-sensitive, high-volume automotive modules where simplicity and standby efficiency are paramount.

FAQ
What is the maximum input voltage the LM9036QM-5.0/NOPB can handle continuously?
The LM9036QM-5.0/NOPB has a maximum operational input voltage of 40 V DC. It can survive transient inputs up to +55 V and −45 V, but continuous operation above 40 V risks exceeding safe operating area limits of the internal PNP pass device and may cause permanent damage. Always limit steady-state VIN to ≤40 V in final designs.
Does the LM9036QM-5.0/NOPB require an external capacitor on the output pin?
Yes, the LM9036QM-5.0/NOPB requires an output capacitor for stability: 10–22 µF with ESR between 0.3 Ω and 8 Ω. Ceramic capacitors meeting these ESR specifications are supported. The capacitor must be placed as close as possible to the OUT and GND pins to minimize loop inductance and ensure reliable regulation across temperature and load.
Is the LM9036QM-5.0/NOPB pin-compatible with other variants in the LM9036Q family?
Yes, all LM9036Q variants - including LM9036QM-3.3/NOPB and LM9036QM-5.0/NOPB - share identical SOIC-8 (D0008A) pinouts and thermal characteristics. Only the output voltage and part marking differ; no PCB layout changes are needed when switching between 3.3 V and 5.0 V versions.
What does the "/NOPB" suffix indicate in LM9036QM-5.0/NOPB?
The "/NOPB" suffix denotes lead-free (Pb-free) and RoHS-compliant packaging with matte tin (Sn) lead finish. This version meets environmental regulations for automotive and industrial applications and is rated for peak reflow temperatures up to 260°C (MSL Level-1). It replaces legacy leaded versions without performance or reliability trade-offs.
How does the LM9036QM-5.0/NOPB behave during thermal shutdown?
When the LM9036QM-5.0/NOPB junction temperature reaches ~150°C, internal thermal shutdown activates, disabling the output. The device remains latched off until the die cools sufficiently - typically by 20–30°C - then automatically resumes regulation. This hysteresis prevents oscillation and protects against sustained overload conditions without external intervention.
