Product details
Overview
NCV5501DT15RKG 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 an internal PNP pass transistor and requires only low-cost ceramic capacitors for stability-ideal for post-SMPS regulation in engine control units.
For engineers reviewing the NCV5501DT15RKG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, DPAK-3 thermal performance (RJA = 80°C/W), reverse bias protection, and absence of enable control-distinguishing it from NCV5500 variants.
Technical Context
The NCV5501DT15RKG implements a bandgap-referenced error amplifier driving a PNP series pass transistor, enabling low dropout while minimizing ground current across load and temperature. Its saturation control logic prevents oversaturation, maintaining stable quiescent current (10 mA max at 500 mA load) and ripple rejection ≥70 dB at 10 kHz.
No enable pin is present-unlike NCV5500 versions-so regulation is always active when input voltage exceeds VOUT + VDO (≥1.73 V). Thermal shutdown triggers at 150°C, and short-circuit protection limits output current to 500–900 mA depending on conditions.
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 and 1–500 mA load-enables precise core supply for automotive microcontrollers. |
| Dropout Voltage | 230 mV at 500 mA load-allows operation with input as low as 1.73 V, critical for cold-crank battery scenarios. |
| Output Current | Up to 500 mA continuous-supports power delivery to multiple low-voltage peripherals without external boost. |
| Ripple Rejection | ≥70 dB at 10 kHz-effectively suppresses switching noise from adjacent DC/DC converters in compact ECU layouts. |
| Thermal Shutdown | Activates at 150°C junction temperature-prevents permanent damage during sustained overload or poor heatsinking. |
| Input Voltage Range | 2.5 V to 16 V-covers full automotive battery range including load dump transients up to ISO 7637-2 Pulse 5a. |
| Ground Current | 10 mA max at 500 mA load-minimizes system-level power loss and simplifies thermal budgeting in sealed modules. |
Pinout & Package
DPAK-3 package (Case 369C), 6.10 mm × 6.54 mm × 2.28 mm, thermally enhanced with exposed tab connected internally to GND. No enable pin-simplifies PCB routing and eliminates external pull-up requirements.
| 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 suppress line transients. |
| Tab. GND | Power ground / thermal path | Internally connected to exposed metal tab; requires minimum 650 mm² copper pour for RJA ≤ 80°C/W. |
| 3. Vout | Regulated 1.5 V output | Delivers up to 500 mA; requires ≥4.7 µF ceramic output capacitor for stability per Figure 17–20. |

FAQ
What is the maximum input voltage rating for NCV5501DT15RKG?
The NCV5501DT15RKG supports an absolute maximum input voltage of +16 V, as specified in the Absolute Maximum Ratings table. This allows safe operation during automotive load-dump transients per ISO 7637-2 Pulse 5a (up to 60 V for 400 ms), provided external clamping (e.g., TVS diode) is used to limit voltage seen by the device. The recommended operating input range remains 2.5 V to 16 V.
Does NCV5501DT15RKG include an enable pin?
No, the NCV5501DT15RKG does not include an enable pin. It is a three-terminal fixed-output LDO in DPAK-3 package (Vin, GND, Vout), unlike the five-pin NCV5500DT15RKG which features EN and ADJ pins. The NCV5501DT15RKG regulates continuously whenever valid input voltage is applied-making it suitable for always-on subsystems like engine sensors or real-time clocks.
What output capacitor value is required for stable operation of NCV5501DT15RKG?
The NCV5501DT15RKG is stable with 4.7 µF ceramic output capacitors, as validated in the Typical Characteristics section (Figures 17–20). For full 500 mA load capability across temperature, use X5R or X7R dielectrics rated ≥6.3 V. Capacitor ESR must remain below 100 mΩ in the 100 kHz–1 MHz range-achievable with standard 0805 or 1206 MLCCs.
Is NCV5501DT15RKG qualified for automotive applications?
Yes, the NCV5501DT15RKG carries the "NCV" prefix indicating automotive qualification: it is AEC-Q100 Grade 1 certified (−40°C to +125°C ambient), PPAP-capable, and manufactured under strict site and change controls. Its design includes reverse bias protection, thermal shutdown, and short-circuit current limiting-meeting functional safety requirements for ASIL-B systems.
How does the dropout voltage of NCV5501DT15RKG vary with temperature?
The dropout voltage of NCV5501DT15RKG increases slightly with junction temperature: typical values are 230 mV at 25°C, ~250 mV at 125°C, and ~215 mV at −40°C (per Figure 7). This positive temperature coefficient ensures robust cold-crank performance while remaining within safe thermal margins during sustained high-temperature operation in under-hood environments.
