Product details
Overview
LM2936QMP-5.0/NOPB from Texas Instruments is an AEC-Q100 Grade 1 qualified ultralow-quiescent-current LDO voltage regulator with fixed 5-V output, 50-mA output current capability, ±2% initial output tolerance, and dropout voltage of 200 mV at 50 mA. It features reverse battery protection, −50-V input transient survival, and thermal shutdown-designed for automotive body control modules, infotainment power rails, and always-on telematics systems.
For engineers reviewing the LM2936QMP-5.0/NOPB datasheet, LM2936QMP-5.0/NOPB pinout, LM2936QMP-5.0/NOPB application, or LM2936QMP-5.0/NOPB equivalent, key selection criteria include quiescent current ≤15 μA at 100 μA load, 5.5–40 V input range, 10 µF/0.3–8 Ω ESR output capacitor requirement, and TO-252-3 surface-mount package thermal performance (RθJA = 50.5°C/W).
Technical Context
The LM2936QMP-5.0/NOPB uses a PNP pass transistor architecture enabling low dropout operation while maintaining ultralow quiescent current across wide input voltage (5.5–40 V) and temperature (−40°C to +125°C) ranges. Its internal bandgap reference and error amplifier deliver ±3% output regulation over line, load, and temperature.
It integrates reverse polarity input protection, −50-V transient survival, short-circuit current limiting (65–250 mA), and thermal shutdown triggered at ~160°C junction temperature. No undervoltage lockout or overvoltage shutdown is implemented-the device enters linear regulation when VIN ≥ VOUT + 1 V and performs optimally when VIN ≥ VOUT + 2 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V, ±2% initial tolerance; ±3% over full line/load/temperature range-ensures stable MCU core or sensor rail without external feedback. |
| Quiescent Current | ≤15 μA at 100 μA load-enables >10-year battery life in automotive keep-alive circuits. |
| Input Voltage Range | 5.5 V to 40 V-supports 12-V and 24-V automotive systems including cold-crank (5.5 V) and load-dump (40 V) conditions. |
| Dropout Voltage | 200 mV typical at 50 mA-allows regulation down to 5.2 V input, critical for post-buck or battery-backed supplies. |
| Output Current | 50 mA maximum continuous-sufficient for powering CAN transceivers, EEPROMs, real-time clocks, and low-power microcontrollers. |
| Transient Protection | Survives −50-V reverse-battery and 60-V positive transients-eliminates need for external TVS diodes in basic automotive designs. |
| Thermal Shutdown | Activates at ~160°C junction temperature; auto-recovers after ~10°C cooldown-prevents permanent damage during overload or poor heatsinking. |
Pinout & Package
LM2936QMP-5.0/NOPB is housed in a 3-pin TO-252 (NDP) surface-mount package with exposed thermal pad (tab). The package measures 6.10 mm × 6.58 mm and provides RθJA = 50.5°C/W on standard JEDEC High-K board-optimized for high ambient temperature environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Unregulated input | Accepts 5.5–40 V; must be decoupled with ≥100 nF ceramic if >3 inches from bulk filter-critical for noise immunity and transient response. |
| GND (Pin 2, Tab) | Ground reference & thermal path | Internal ground connection and exposed metal tab-must be soldered to ≥1 cm² copper pour for thermal performance and EMI reduction. |
| OUT (Pin 3) | Regulated output | Delivers stable 5 V; requires ≥10 µF output capacitor with 0.3–8 Ω ESR-ceramic caps need series resistor to meet ESR spec. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation-meets automotive electronics reliability requirements without derating. |
| Reverse battery protection | Withstands −15 V input with <0.3 V reverse output-prevents backfeed and damage during battery installation errors. |
| Ultralow IQ standby mode | 15 μA max at 100 μA load-reduces parasitic drain in always-on vehicle networks (e.g., LIN, CAN wake-up receivers). |
| Integrated short-circuit limit | 65–250 mA current foldback-limits fault energy during output shorts, preventing PCB trace burnout or connector arcing. |
| Stable with ceramic output caps | Supports 10 µF MLCC + series resistor (0.5–1 Ω)-enables compact, low-ESR, high-reliability filtering without tantalum or aluminum electrolytics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7B6750QDDARQ1 | Higher IQ (25 μA), lower dropout (175 mV @ 50 mA), integrated enable pin, same 5-V output and AEC-Q100 Grade 1 rating. | Requires enable control logic; better suited for systems needing active sequencing or dynamic power gating. | Select when programmable enable and tighter dropout are required; verify layout compatibility with SO PowerPAD package. |
| NCP163AMX500TBG | Lower IQ (1.5 μA), 150-mA output, but only AEC-Q200 qualified (not Q100); no reverse-battery protection. | Lacks automotive-grade transient robustness; suitable for industrial or commercial battery-powered devices where cost and ultra-low IQ dominate. | Choose only for non-safety-critical, non-automotive applications requiring sub-μA standby; not drop-in for LM2936QMP-5.0/NOPB in automotive designs. |
Compared with TPS7B6750QDDARQ1 and NCP163AMX500TBG, the LM2936QMP-5.0/NOPB offers superior reverse-battery survivability (−50 V), proven AEC-Q100 Grade 1 qualification, and simpler enable-free operation-making it optimal for cost-sensitive, high-reliability automotive subsystems where minimal external components and field-proven ruggedness are prioritized.

FAQ
What is the minimum input voltage required for regulation in the LM2936QMP-5.0/NOPB?
The LM2936QMP-5.0/NOPB enters regulation when input voltage reaches VOUT + 1 V (i.e., ≥6.0 V), but optimal dynamic performance-including PSRR and transient response-requires VIN ≥ VOUT + 2 V (≥7.0 V). Below 6.0 V, output tracks input with no regulation. This behavior is inherent to its PNP pass transistor architecture and is documented in Section 7.4 of the LM2936Q datasheet.
Does the LM2936QMP-5.0/NOPB include a shutdown pin?
No, the LM2936QMP-5.0/NOPB does not include a shutdown (SD) pin. That feature is exclusive to the LM2936QHBMA variant (8-pin SOIC with SD pin). The LM2936QMP-5.0/NOPB is a 3-pin TO-252 device with IN, GND, and OUT terminals only-operation is always enabled when input voltage is within specification.
What output capacitor is required for stability with the LM2936QMP-5.0/NOPB?
The LM2936QMP-5.0/NOPB requires a minimum 10 µF output capacitor with ESR between 0.3 Ω and 8 Ω. Ceramic capacitors may be used only if a series resistor (typically 0.5–1 Ω) is added to meet the ESR requirement. X5R or X7R dielectrics are recommended to maintain capacitance across temperature and DC bias. This is specified in Section 8.2.2.1 of the LM2936Q datasheet.
Can the LM2936QMP-5.0/NOPB withstand reverse battery connection?
Yes, the LM2936QMP-5.0/NOPB provides reverse battery protection: it survives −15 V applied to the IN pin with output voltage clamped to <−0.3 V, preventing damage to downstream circuitry. It also withstands −50-V transients for 1 ms-critical for automotive assembly and jump-start scenarios. This is confirmed in Sections 6.5–6.7 and 7.3.2 of the LM2936Q datasheet.
What is the thermal performance of the LM2936QMP-5.0/NOPB in its TO-252 package?
The LM2936QMP-5.0/NOPB in TO-252 (NDP) package has RθJA = 50.5°C/W on JEDEC High-K board, RθJC(bot) = 1.6°C/W, and ψJB = 29.3°C/W. For reliable operation at 50 mA and 40 V input, the PCB must include ≥1 cm² 2-oz copper connected to the exposed tab. Junction temperature must remain below 150°C; thermal shutdown activates near 160°C with automatic recovery.
