Product details
Overview
NCV5501DT15G from onsemi is an automotive-grade fixed-output LDO voltage regulator delivering 1.5 V at up to 500 mA, with ±2.9% output voltage accuracy, 230 mV dropout at full load, and operation from −40°C to +125°C ambient. It uses a PNP pass transistor for low-dropout performance and integrates thermal shutdown and short-circuit protection - ideal for post-SMPS regulation in engine control units.
For engineers reviewing the NCV5501DT15G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, DPAK-3 package thermal performance (RJA = 60°C/W), fixed 1.5 V output without enable control, and stable operation with low-cost ceramic capacitors.
Technical Context
The NCV5501DT15G employs a bandgap-referenced error amplifier driving a PNP series pass transistor, enabling ultra-low dropout (230 mV @ 500 mA) while minimizing ground current (500 µA typical at 500 mA). Its saturation control logic prevents pass transistor oversaturation, preserving regulation across temperature and load.
No enable pin is present - unlike NCP/NCV5500 variants - making it a simplified, always-on regulator optimized for cost-sensitive, high-reliability automotive subsystems where logical on/off control is unnecessary. Reverse bias protection operates when VOUT − VIN ≤ 7 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2.9% (±43.5 mV) over −40°C to +125°C - ensures stable core voltage for 1.5 V logic or analog circuitry under extreme thermal stress. |
| Max Output Current | 500 mA continuous - supports mid-power microcontrollers, CAN transceivers, or sensor signal chains without external boost stages. |
| Dropout Voltage | 230 mV at 500 mA - enables operation from 1.73 V input, critical for battery-fed systems during cold-crank (e.g., 9 V nominal battery down to ~6 V). |
| Ground Current | 500 µA at 500 mA load - minimizes system quiescent power, supporting low-power sleep modes in always-on vehicle modules. |
| Thermal Shutdown | Activates at 150°C junction temperature - protects against sustained overload or poor heatsinking in sealed enclosures. |
| Input Voltage Range | 2.5 V to 16 V - accommodates wide automotive supply variations including load-dump transients up to ISO 7637-2 Pulse 5a. |
| Ripple Rejection | 75 dB at 120 Hz (100 mA load) - suppresses switching noise from upstream DC/DC converters feeding sensitive analog circuits. |
Pinout & Package
DPAK-3 (Case 369C) package with exposed tab thermally connected to GND - provides low RJC (5.2°C/W) for efficient heat transfer to PCB copper pour or heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1. Vin | Positive input supply | Accepts 2.5–16 V DC; must be decoupled with ≥10 µF ceramic capacitor near pin to stabilize line transients. |
| Tab. GND | Ground reference and thermal path | Internally bonded to die substrate; requires ≥650 mm² 1 oz copper pad for rated RJA = 60°C/W. |
| 3. Vout | Regulated 1.5 V output | Delivers up to 500 mA; requires ≥4.7 µF ceramic output capacitor for stability per ESR vs. load current curves. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Rated for automotive Grade 1 (−40°C to +125°C ambient) with PPAP capability - meets OEM requirements for engine bay and transmission control modules. |
| Stable with ceramic capacitors | Validated for 1–10 µF X7R/X5R ceramics across full load range - eliminates need for costly tantalum or aluminum electrolytics. |
| Reverse bias protection | Prevents reverse current flow when VOUT > VIN by up to 7 V - safeguards against backfeeding during battery disconnect or hot-swap events. |
| Short-circuit protection | Limits output current to 500–900 mA during fault - avoids catastrophic failure and enables safe auto-recovery after fault removal. |
| Pb-free, RoHS-compliant | Meets J-STD-609 Class 1 moisture sensitivity and JEDEC reflow profiles (265°C peak) - compatible with standard lead-free SMT assembly. |
Applications
| Engine Control Unit (ECU) Core Power | Automotive Camera Module Bias Supply |
|---|---|

IC Role / Device Role / Timing Role: Low-noise local regulator isolating sensor AFE from noisy 3.3 V digital rail. Use Value: 75 dB ripple rejection at 120 Hz suppresses switching artifacts from adjacent DC/DC, preventing image banding or fixed-pattern noise. |
| Body Control Module (BCM) Sensor Interface | Automotive Infotainment Audio Codec Supply |
Use Scenario: Provides regulated 1.5 V to Hall-effect position sensors and LIN transceivers in door module assemblies. IC Role / Device Role / Timing Role: Always-on, non-shutdown LDO for fail-safe sensor monitoring during vehicle sleep mode. Use Value: 500 µA ground current at full load minimizes parasitic drain, extending battery life beyond ISO 19453-3 requirements for 30-day parking mode. |
Use Scenario: Powers delta-sigma audio ADC/DAC cores in head unit SoCs requiring ultra-low noise 1.5 V analog supply. IC Role / Device Role / Timing Role: Low-noise linear regulator placed directly at codec VDDA pin to minimize PSRR degradation. Use Value: 18 µVRMS output noise (10 Hz–100 kHz) preserves SNR > 105 dB in high-fidelity automotive audio paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8170AD150X | Lower max current (300 mA), higher dropout (300 mV @ 300 mA), same 1.5 V fixed output and AEC-Q100 Grade 1 rating. | Suitable only for sub-300 mA loads; insufficient for MCU core rails but adequate for sensor biasing. | Select NCV5501DT15G when 500 mA output and 230 mV dropout are required; choose NCV8170AD150X only if board space or cost constraints favor smaller DFN package. |
| TLV73315PDBVR | Non-automotive grade (−40°C to +125°C not AEC-Q100 qualified), lower IQ (60 µA), but same 1.5 V output and 500 mA rating. | Lacks PPAP documentation and site change control - unsuitable for Tier 1 automotive production, acceptable for industrial prototypes. | Use TLV73315PDBVR for cost-sensitive non-automotive designs; retain NCV5501DT15G for production automotive programs requiring full AEC-Q100 traceability. |
Compared with NCV8170AD150X and TLV73315PDBVR, the NCV5501DT15G uniquely delivers 500 mA at 230 mV dropout with full AEC-Q100 Grade 1 qualification and PPAP support - making it the only option meeting OEM requirements for high-current, high-temperature automotive core power rails.

FAQ
What is the maximum input voltage for the NCV5501DT15G?
The NCV5501DT15G supports an absolute maximum input voltage of +16 V, with recommended operating range from 2.5 V (or VOUT + VDO) up to 16 V. This allows compatibility with automotive 12 V systems during load-dump events per ISO 7637-2 Pulse 5a, provided external clamping is used above 16 V.
Does the NCV5501DT15G have an enable pin?
No, the NCV5501DT15G does not include an enable pin. It is a simplified variant of the NCV5500 series designed for always-on operation. The NCV5500DT15RKG offers enable functionality in DPAK-5 packaging, while the NCV5501DT15G uses DPAK-3 with pins limited to Vin, GND (tab), and Vout.
What output capacitor value is required for stability with the NCV5501DT15G?
The NCV5501DT15G is stable with 4.7 µF ceramic output capacitors (X7R/X5R, 10 V rating). Per Figure 17–20 in the datasheet, stability is maintained across 1–10 µF range with ESR < 10 Ω at 100 kHz. Larger values improve transient response but do not affect loop stability.
Is the NCV5501DT15G pin-compatible with other regulators in the NCV5500 family?
No - the NCV5501DT15G uses a 3-pin DPAK-3 package (Vin, GND, Vout), whereas NCV5500 variants use 5-pin DPAK-5 (adding EN and NC/ADJ) or 8-pin SOIC-8. No mechanical or electrical pin compatibility exists; PCB layout must be redesigned for NCV5501DT15G integration.
What thermal derating applies to the NCV5501DT15G at 125°C ambient?
At TA = 125°C, the NCV5501DT15G's maximum continuous output current is reduced to ~320 mA (calculated using RJA = 60°C/W and TJ(MAX) = 150°C). Full 500 mA operation requires TA ≤ 80°C with adequate PCB copper area; thermal simulation or testing is recommended for final design validation.
