Product details
Overview
NCV78L05ABPRMG from onsemi is an automotive-grade, fixed-output +5.0 V linear voltage regulator delivering up to 100 mA with internal short-circuit and thermal overload protection. It operates across −40°C to +125°C, features 4.75–5.25 V output tolerance at 40 mA load, 1.7 V dropout, and 49 dB ripple rejection at 120 Hz - ideal for engine control units and body electronics requiring AEC-Q100-compliant power conditioning.
For engineers reviewing the NCV78L05ABPRMG datasheet, pinout, applications, or equivalent options, key selection criteria include its TO-92 package, −40°C to +125°C automotive temperature range, guaranteed 5.0 V ±5% output, low quiescent current (≤6.0 mA), and Pb-free construction compliant with PPAP requirements.
Technical Context
The NCV78L05ABPRMG uses a monolithic bipolar design with internal current limiting and thermal shutdown circuitry. Its architecture provides stable regulation without external capacitors in most low-noise, low-current applications, though input bypassing with ≥0.33 µF is recommended for long trace runs.
It exhibits fixed 5.0 V output via precision bandgap reference and error amplifier feedback. Dropout voltage remains constant at 1.7 V across temperature and load, and ripple rejection degrades only marginally from 49 dB (typ) at 120 Hz to 41 dB (min) under worst-case conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.75–5.25 V at 1.0–40 mA load and −40°C to +125°C - ensures logic-level compatibility with 5 V microcontrollers and sensors. |
| Maximum Output Current | 100 mA continuous - supports small-signal analog circuits, CAN transceiver biasing, and MCU peripherals. |
| Dropout Voltage | 1.7 V typical at 25°C - enables operation from 6.7 V minimum input, suitable for 12 V battery systems with ripple. |
| Ripple Rejection | 41–49 dB at 120 Hz - suppresses alternator noise and switching supply coupling into sensitive analog rails. |
| Quiescent Current | 3.8–6.0 mA across temperature - minimizes standby power loss in always-on automotive modules. |
| Thermal Resistance (RJA) | 200 °C/W (TO-92) - requires minimal PCB copper area for thermal management in space-constrained ECUs. |
| AEC-Q100 Grade | Qualified to Grade 1 (−40°C to +125°C) - certified for engine bay and transmission control applications. |
Pinout & Package
NCV78L05ABPRMG is housed in a Pb-free TO-92 (Case 29-10) plastic package with bent leads, rated for 1 W dissipation. The package has three terminals: Input (VIN), Ground (GND), and Output (VOUT), with pin 1 = Output, pin 2 = Ground, pin 3 = Input (top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output (VOUT) | Regulated +5.0 V supply rail - connects directly to load ICs; no external sense line required. |
| 2 | Ground (GND) | Common reference for input and output - must share ground plane with upstream filter and downstream loads. |
| 3 | Input (VIN) | Unregulated DC input - accepts 7.0–20 V per spec; requires ≥2.0 V headroom above VOUT for regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 qualified and PPAP capable - meets OEM requirements for production vehicle electronics. |
| Internal protection | Thermal shutdown + short-circuit current limiting - eliminates need for external fusing or thermal sensors. |
| No external components | Stable with only optional 0.33 µF input and 0.1 µF output capacitors - reduces BOM count and layout area. |
| Low output impedance | Superior to Zener-diode/resistor regulators - improves transient response and load regulation (≤60 mV variation). |
| Pb-free construction | RoHS-compliant TO-92 package - satisfies global environmental compliance and solder reflow profiles. |
Applications
| Engine Control Unit (ECU) Sensor Biasing | Body Control Module (BCM) Power Rail |
|---|---|
Use Scenario: Providing stable 5 V bias to oxygen sensors, knock sensors, and crankshaft position sensors in engine compartments. IC Role / Device Role / Timing Role: Primary low-noise analog supply regulator - maintains sensor accuracy under wide temperature and vibration conditions. Use Value: Guaranteed −40°C to +125°C operation and 49 dB ripple rejection prevent sensor drift during cold starts or high-load alternator noise. |
Use Scenario: Powering door lock actuators, interior lighting drivers, and LIN transceivers in vehicle body electronics. IC Role / Device Role / Timing Role: Local point-of-load regulator - decouples BCM logic from noisy 12 V battery bus. Use Value: Internal short-circuit protection prevents latch-up during actuator stall events; 100 mA output supports multiple parallel loads. |
| Instrument Cluster Microcontroller Supply | Telematics Module Standby Rail |
Use Scenario: Delivering clean 5 V to ARM Cortex-M based instrument cluster MCUs during ignition-on and sleep modes. IC Role / Device Role / Timing Role: Always-on regulated supply - maintains RTC and CAN wake-up circuitry during vehicle sleep. Use Value: Low 3.8 mA quiescent current minimizes battery drain; AEC-Q100 qualification ensures reliability over 15-year vehicle life. |
Use Scenario: Powering GPS/GNSS receivers and cellular modem control logic in telematics control units (TCUs). IC Role / Device Role / Timing Role: Secondary regulated rail - isolates RF-sensitive analog sections from digital switching noise. Use Value: 41 dB min ripple rejection suppresses digital noise coupling into GNSS front-end; TO-92 footprint simplifies placement near RF modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC78L05ABPRMG | Same TO-92 package, but commercial temp range (0°C to +125°C); no AEC-Q100 qualification. | Suitable for non-automotive industrial or consumer applications where extended temperature is not required. | Select when cost sensitivity outweighs automotive qualification needs and ambient conditions remain >0°C. |
| NCV78L05ABDR2G | SOIC-8 package, same −40°C to +125°C rating and electrical specs; higher thermal resistance (RJA ≈ 150–180 °C/W depending on PCB copper). | Better suited for automated SMT assembly and higher-density layouts where TO-92 lead spacing is problematic. | Choose for surface-mount production lines or when board space allows larger footprint and improved manufacturability. |
Compared with MC78L05ABPRMG and NCV78L05ABDR2G, the NCV78L05ABPRMG uniquely combines automotive qualification, through-hole assembly compatibility, and minimal thermal interface requirements - making it optimal for legacy ECU designs and repair-replacement scenarios where TO-92 mounting is fixed.

FAQ
What is the operating temperature range of the NCV78L05ABPRMG?
The NCV78L05ABPRMG is rated for −40°C to +125°C junction temperature, meeting AEC-Q100 Grade 1 requirements. This range is validated across all electrical parameters in the datasheet, including output voltage stability, dropout, and ripple rejection - making it suitable for under-hood automotive applications where ambient temperatures exceed 105°C.
Does the NCV78L05ABPRMG require external capacitors for stability?
The NCV78L05ABPRMG is internally compensated and does not require external capacitors for basic stability. However, a 0.33 µF input capacitor is recommended when the regulator is located more than a few centimeters from the main power filter, and a 0.1 µF output capacitor improves transient response - both values are specified in the standard application circuit of the datasheet.
What is the maximum input voltage the NCV78L05ABPRMG can withstand?
The NCV78L05ABPRMG supports up to 30 V DC input for the 5 V version (per Absolute Maximum Ratings table). However, sustained operation above 20 V significantly increases power dissipation and thermal stress - the recommended maximum continuous input is 20 V for reliable operation within the −40°C to +125°C range.
How does the NCV78L05ABPRMG compare to Zener diode-based regulation?
The NCV78L05ABPRMG delivers substantially lower output impedance and quiescent current versus Zener-resistor solutions. Its 4.75–5.25 V output tolerance, 49 dB ripple rejection, and built-in thermal/short-circuit protection eliminate discrete protection components - reducing total solution size, cost, and failure modes compared to passive regulation.
Is the NCV78L05ABPRMG pin-compatible with other TO-92 linear regulators?
The NCV78L05ABPRMG uses standard TO-92 pinout (pin 1 = VOUT, pin 2 = GND, pin 3 = VIN), matching industry-standard 78Lxx devices. However, direct substitution requires verification of thermal limits, input voltage range, and qualification level - for example, replacing a commercial MC78L05ABPRMG with NCV78L05ABPRMG adds AEC-Q100 compliance but does not change pin assignment.
