Product details
Overview
LM9036DT-5.0/NOPB from Texas Instruments is a fixed 5.0V, 50mA ultra-low quiescent current linear voltage regulator in TO-252 (DPAK) package, featuring ≤25µA ground pin current at 0.1mA load, 200mV typical dropout at full load, and −45V reverse transient protection - designed for automotive battery-supplied systems requiring extended standby operation.
For engineers reviewing the LM9036DT-5.0/NOPB datasheet, LM9036DT-5.0/NOPB pinout, LM9036DT-5.0/NOPB application, or LM9036DT-5.0/NOPB equivalent, key selection criteria include ultra-low IQ performance under light load, reverse-battery survivability, thermal derating at elevated ambient temperatures, and compatibility with low-ESR ceramic output capacitors (0.3–8Ω).
Technical Context
The LM9036DT-5.0/NOPB employs a PNP pass transistor architecture enabling true low-dropout operation while maintaining regulation down to 40V input. Its internal circuitry integrates reverse-battery protection, short-circuit current limiting (65–250mA), and thermal shutdown triggered at ~150°C junction temperature.
Unlike standard LDOs, it sustains regulation across −40°C to +125°C ambient and tolerates −45V transients without damage. Its 4.75–5.25V output tolerance over line, load, and temperature ensures stable supply for microcontrollers and sensors in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±5% (4.75–5.25V) over full operating range - eliminates external feedback network and supports direct MCU core/sensor rail use. |
| Max Output Current | 50mA continuous - sufficient for low-power microcontrollers, CAN transceivers, and analog front-ends in body electronics modules. |
| Quiescent Current | ≤25µA at 0.1mA load - enables >10-year battery life in always-on vehicle modules (e.g., door lock controllers, tire pressure monitors). |
| Dropout Voltage | 200mV typical at 50mA - allows operation from 5.2V input when VOUT = 5.0V, critical for post-ignition battery voltage sag scenarios. |
| Reverse Transient Protection | −45V survival - withstands load-dump and jump-start transients common in 12V automotive electrical systems without external clamping. |
| Operating Voltage Range | Up to 40V max operational input - supports wide-input automotive applications including start-stop and dual-battery architectures. |
| Thermal Shutdown Threshold | ~150°C junction - protects against sustained overload or poor PCB heatsinking; auto-recovery upon cooling. |
Pinout & Package
LM9036DT-5.0/NOPB uses the TO-252-3 (NDP) thermally enhanced surface-mount package with exposed drain pad (PowerPAD™) for improved heat dissipation. The package measures 6.73 × 6.22 mm with 2.55 mm max height and is RoHS-compliant with Sn lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Input) | VIN | Main power input terminal; accepts 5.5–40V DC; requires local 10–22µF low-ESR capacitor (0.3–8Ω) within 2″ of pin. |
| 2 (Ground) | GND | Reference and return path; electrically connected to exposed thermal pad - must be soldered to ≥1 in² 2oz copper pour for θJA ≈50°C/W. |
| 3 (Output) | VOUT | Regulated 5.0V output; supplies downstream logic/sensors; stability requires COUT placed adjacent to VOUT and GND pins. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ground pin current | ≤25µA at 0.1mA load - minimizes parasitic drain on vehicle battery during sleep mode. |
| Integrated reverse-battery protection | Survives −45V transients - eliminates need for external series diode or TVS, reducing BOM count and forward voltage drop. |
| Thermally robust construction | Exposed PowerPAD™ with θJC = 11°C/W - enables 50mA output at +85°C ambient when properly mounted on thermal copper. |
| Short-circuit and thermal fault protection | Auto-limited peak current (65–250mA) and 150°C shutdown - prevents catastrophic failure during wiring faults or output shorts. |
| Stable with ceramic output capacitors | Validated for 10–22µF, 0.3–8Ω ESR - supports compact, high-reliability designs without tantalum or electrolytic capacitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-IQ automotive voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76350DBVR | 250nA IQ (vs. 25µA), 100mA output, but only −20V reverse rating and no integrated reverse-battery protection. | Limited to non-automotive industrial battery systems; requires external reverse-protection diode for automotive use. | Select when sub-µA quiescent current dominates design priority and reverse transients are absent or externally clamped. |
| TLV73350PDQNR | 65µA IQ (vs. 25µA), 300mA output, 200mV dropout, but rated only to +105°C and lacks −45V reverse transient capability. | Suitable for cabin electronics (infotainment, HVAC) but not under-hood or chassis-mounted modules. | Choose for higher-current, lower-cost applications where extended temperature and reverse-transient immunity are not required. |
Compared with TPS76350DBVR and TLV73350PDQNR, the LM9036DT-5.0/NOPB uniquely balances ultra-low IQ, automotive-grade reverse-transient resilience, and extended temperature operation - making it the only option qualified for under-hood body control and sensor supply roles without supplemental protection circuitry.

FAQ
What is the maximum input voltage for continuous operation of the LM9036DT-5.0/NOPB?
The LM9036DT-5.0/NOPB supports continuous operation up to 40V input voltage. While it can survive transient inputs up to +55V and −45V, sustained operation above 40V violates its absolute maximum rating and risks permanent damage due to safe-operating-area limitations in the internal PNP pass device.
Does the LM9036DT-5.0/NOPB require an external diode for reverse-battery protection?
No, the LM9036DT-5.0/NOPB includes integrated reverse-battery protection and survives −45V input transients without external components. This eliminates the forward voltage drop and board space associated with discrete series diodes, preserving efficiency in low-voltage battery scenarios.
What output capacitor is recommended for stable operation of the LM9036DT-5.0/NOPB?
The LM9036DT-5.0/NOPB is stable with 10–22µF ceramic output capacitors having ESR between 0.3Ω and 8Ω. TI specifies that the capacitor must be placed adjacent to the VOUT and GND pins, and recommends X7R or X5R dielectrics rated for the full −40°C to +125°C operating range.
Can the LM9036DT-5.0/NOPB deliver its full 50mA output at +125°C ambient temperature?
No - thermal derating applies. With the TO-252 package mounted on standard FR-4 (no thermal pad), θJA ≈125°C/W limits usable power dissipation. At +125°C ambient, the LM9036DT-5.0/NOPB enters thermal shutdown before delivering 50mA; full output is only sustainable below ~85°C ambient with proper PCB thermal design.
Is the LM9036DT-5.0/NOPB pin-compatible with other regulators in the LM9036 family?
Yes - all TO-252 variants (e.g., LM9036DT-3.3/NOPB, LM9036DTX-5.0/NOPB) share identical pinout and footprint. However, output voltage and tape-and-reel packaging differ; electrical behavior (e.g., dropout, PSRR) remains consistent across fixed-output versions.
