Product details
Overview
NCV8560SN300T1G from onsemi is a fixed-output 3.0 V, 150 mA low-dropout (LDO) linear regulator in TSOP−5 package, featuring 150 mV dropout at full load, ±2% output voltage tolerance over −40°C to +125°C, and AEC−Q100 qualification for automotive use. It delivers stable power to noise-sensitive RF stages, camera modules, and portable instrumentation with fast 15 µs enable turn-on.
For engineers reviewing the NCV8560SN300T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout performance at 150 mA, thermal shutdown behavior at 175°C, PSRR of 62 dB at 120 Hz, and compatibility with low-ESR ceramic output capacitors down to 1.0 µF.
Technical Context
The NCV8560SN300T1G implements a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR without requiring external compensation. Its internal bandgap reference and error amplifier maintain regulation across input voltages from 3.5 V to 6.0 V while supporting operation down to 1.75 V when VOUT + VDO is satisfied.
Thermal protection activates at ~175°C with 10°C hysteresis, and the ENABLE pin provides logic-level control (0.9 V threshold high, 0.4 V low) with <100 nA bias current. Ground current remains stable at 140 µA typical under 150 mA load, supporting low-quiescent-power battery applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over −40°C to +125°C - ensures stable supply for 3.3 V I/O interfaces with margin |
| Max Output Current | 150 mA - sufficient for powering microcontrollers, sensors, and RF front-end ICs |
| Dropout Voltage | 75 mV at 150 mA - enables operation from single-cell Li-ion (3.0 V nominal) down to 2.925 V |
| PSRR | 62 dB @ 120 Hz - suppresses switching noise from upstream DC/DC converters in SMPS post-regulation |
| Noise Voltage | 50 µVrms (10 Hz–100 kHz) - suitable for VCOs and analog signal chains without bypass capacitor |
| Enable Threshold | 0.9 V (rising), 0.4 V (falling) - compatible with 1.8 V/3.3 V GPIO without level-shifting |
| Thermal Shutdown | 175°C activation with 10°C hysteresis - protects against sustained overload or poor PCB heatsinking |
Pinout & Package
NCV8560SN300T1G is housed in a Pb-free TSOP−5 (Case 483) package: 3.00 mm × 1.50 mm × 0.95 mm, 0.95 mm pitch, with exposed pad not connected internally. Thermal resistance RJA = 205°C/W under standard JEDEC conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Positive power supply input | Accepts 3.5 V to 6.0 V input; must be decoupled with ≥1.0 µF ceramic capacitor near pin |
| 2 - GND | Power ground reference | Primary return path for load and quiescent current; connects to PCB ground plane for thermal conduction |
| 3 - ENABLE | Logic-controlled on/off input | Pulled high to VIN for always-on operation; driven low (<0.4 V) to reduce quiescent current to ≤1.0 µA |
| 4 - VOUT | Regulated 3.0 V output | Delivers up to 150 mA; requires ≥1.0 µF ceramic output capacitor for stability and transient response |
| 5 - GND | Secondary ground terminal | Reduces ground loop impedance; must be tied to same ground plane as Pin 2 for optimal noise rejection |
Key Features
| Feature | Design Value |
|---|---|
| AEC−Q100 qualified | Qualified to Grade 1 (−40°C to +125°C ambient), PPAP-capable - meets automotive electronics reliability requirements |
| Ultra-low dropout | 75 mV at 150 mA - extends battery runtime in portable systems by minimizing headroom loss |
| Fast enable response | 15 µs turn-on time - supports rapid power sequencing in multi-rail embedded systems |
| No minimum ESR required | Stable with ceramic capacitors ≥1.0 µF - eliminates need for costly tantalum or polymer caps |
| Low noise without bypass cap | 50 µVrms noise floor - simplifies layout for RF/analog circuits where space is constrained |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73330PDBVR | 300 mA output, 170 mV dropout at 300 mA, SOT-23-5 package, no AEC-Q100 qualification | Higher current capability but lacks automotive qualification and has higher dropout at 150 mA (120 mV vs. 75 mV) | Select when >150 mA is needed and automotive compliance is not required |
| TPS7B6733QPWPRQ1 | 200 mA output, 300 mV dropout at 200 mA, wettable flank QFN, AEC-Q100 Grade 1 | Higher dropout and larger footprint; includes reverse polarity protection and adjustable soft-start | Select when reverse-voltage protection or programmable start-up timing is mandatory |
Compared with TLV73330PDBVR and TPS7B6733QPWPRQ1, the NCV8560SN300T1G offers the lowest dropout at 150 mA and smallest TSOP−5 footprint among AEC-Q100 qualified 3.0 V LDOs, making it optimal for space-constrained automotive modules where efficiency and qualification are critical.

FAQ
What is the maximum input voltage rating for the NCV8560SN300T1G?
The NCV8560SN300T1G has an absolute maximum input voltage of 6.0 V. Operation above this level risks permanent damage. The recommended operating range is 3.5 V to 6.0 V for 3.0 V output, ensuring sufficient headroom above the 75 mV dropout voltage while maintaining regulation across temperature and load extremes.
Does the NCV8560SN300T1G require an external bypass capacitor for noise reduction?
No, the NCV8560SN300T1G does not require an external bypass capacitor. Its internal design achieves a typical output noise of 50 µVrms (10 Hz–100 kHz) without any additional capacitor, unlike many competing low-noise LDOs that mandate external 10 nF–100 nF bypass caps and suffer slower startup times.
How is thermal performance affected by PCB layout for the NCV8560SN300T1G?
Thermal performance of the NCV8560SN300T1G depends heavily on PCB copper area: its RJA drops from 205°C/W (standard JEDEC) to ~150°C/W with ≥150 mm² of 1 oz copper connected to the two GND pins. Poor layout-such as narrow traces or isolated pads-can cause junction temperatures to exceed 125°C at 150 mA, triggering thermal shutdown.
Can the NCV8560SN300T1G be used in adjustable-output configurations?
No, the NCV8560SN300T1G is a fixed 3.0 V output variant. Adjustable versions (e.g., NCV8560SNADJT1G) use the ADJ pin, but the SN300 suffix indicates a fixed-voltage device where Pin 3 is ENABLE and Pin 5 is GND-no ADJ functionality is present. Attempting external resistor networks will not alter the output voltage.
What is the quiescent current consumption of the NCV8560SN300T1G under full load?
At 150 mA output current and 25°C ambient, the NCV8560SN300T1G draws approximately 140 µA of ground current (IGND). This value increases slightly with temperature but remains below 180 µA across the full −40°C to +125°C operating range, contributing to high efficiency in battery-powered applications.
