Product details
Overview
NCP583XV31T2G from onsemi is a 3.1 V, 150 mA ultra-low quiescent current CMOS LDO regulator in SOT-563 package, featuring 250 mV dropout at full load, ±2% output voltage accuracy, and active-high enable control-designed for battery-powered portable equipment requiring stable low-power voltage regulation.
For engineers reviewing the NCP583XV31T2G datasheet, pinout, applications, or equivalent options, key selection considerations include its 1.0 µA quiescent current, 0.1 µA shutdown current, 3.1 V fixed output, SOT-563 thermal resistance (200°C/W), and compatibility with 1.0 µF ceramic output capacitance.
Technical Context
The NCP583XV31T2G implements a CMOS-based LDO architecture with internal reference, error amplifier, and foldback current limiting. It operates across 1.7–6.0 V input range and maintains regulation down to 250 mV dropout at 150 mA output current for its 3.1 V nominal output.
Its enable pin (CE) accepts logic-level inputs (VTH,ENH = 1.2–6.0 V, VTH,ENL = 0–0.3 V), supporting system-level power sequencing. Thermal protection and short-circuit foldback ensure robust operation under transient overloads and elevated ambient temperatures up to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.1 V ±2% - ensures precise rail generation for 3.3 V–tolerant I/O without external feedback components. |
| Max Output Current | 150 mA - supports moderate-power microcontrollers, sensors, and RF modules in space-constrained designs. |
| Quiescent Current | 1.0 µA typical - extends battery life in always-on or sleep-mode applications such as wearables and remote sensors. |
| Dropout Voltage | 250 mV at 150 mA - enables regulation from 3.35 V input, critical for single-cell Li-ion or Li-poly systems near end-of-discharge. |
| Line Regulation | 0.05%/V typical - minimizes output variation across wide input swings, improving stability in noisy or variable-supply environments. |
| Load Regulation | 20 mV typical (1 µA–150 mA) - maintains tight voltage control during dynamic load transitions in portable instrumentation. |
| Shutdown Current | 0.1 µA typical - reduces standby leakage to negligible levels when CE is deasserted, enabling deep-sleep system states. |
| Thermal Resistance (RJA) | 200°C/W (SOT-563) - defines junction-to-ambient temperature rise per watt; requires minimal PCB copper for thermal management. |
Pinout & Package
SOT-563 (Case 463A) surface-mount package: 1.6 mm × 1.2 mm × 0.6 mm body, 6-pin configuration with two ground pins for improved thermal and noise performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Vin) | Input power supply | Accepts 1.7–6.0 V DC; requires 1.0 µF ceramic decoupling capacitor to GND for stability. |
| 2 (GND) | Power ground (pin 2) | Primary ground return path; connects to PCB ground plane to minimize noise coupling into regulation loop. |
| 3 (Vout) | Regulated output | Delivers fixed 3.1 V ±2%; requires 0.1 µF ceramic capacitor close to pin for transient response optimization. |
| 4 (NC) | No connect | Internally unconnected; must remain floating-no external connection or PCB trace allowed. |
| 5 (GND) | Power ground (pin 5) | Secondary ground terminal; ties to same ground net as pin 2 to reduce impedance and improve thermal dissipation. |
| 6 (CE) | Chip enable (active high) | Logic-controlled on/off; drives high (>1.2 V) to enable regulation, low (<0.3 V) to enter 0.1 µA shutdown mode. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 1.0 µA typical enables >1-year battery life in coin-cell–powered IoT endpoints with 10 µA average system current. |
| Foldback current limit | 40 mA short-circuit current limits power dissipation during fault conditions, preventing thermal runaway in compact layouts. |
| Low temperature drift | ±100 ppm/°C output voltage drift ensures <±1.3% total variation over −40°C to +85°C, critical for precision analog front-ends. |
| Wide input range | 1.7–6.0 V operation supports direct connection to single-cell Li-ion (2.7–4.2 V), alkaline (1.5 V × 2), or USB-powered systems. |
| Pb-free & RoHS compliant | SOT-563 package meets global environmental compliance requirements without derating or reliability penalties. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3102E/TT | 3.1 V fixed, 250 mA, 1.6 µA IQ, SOT-23-5; higher IQ and output current, but no NC pin or dual-GND layout. | Supports higher load currents but lacks dual-GND thermal advantage; less optimal for ultra-low-noise analog rails. | Select when >150 mA output or SOT-23 footprint compatibility is required; verify layout noise sensitivity. |
| Torex XC6206P312MR-G | 3.1 V fixed, 150 mA, 1.0 µA IQ, SOT-25; identical quiescent current but only one GND pin and 300°C/W RJA. | Higher thermal resistance limits continuous 150 mA operation in confined spaces without added copper. | Prefer for cost-sensitive designs where thermal margin is sufficient; avoid in thermally constrained enclosures. |
Compared with MCP1700T-3102E/TT and XC6206P312MR-G, the NCP583XV31T2G offers superior thermal performance (200°C/W vs. ≥300°C/W) and dual-GND layout for lower noise, making it optimal for precision analog and space-limited battery systems.

FAQ
What is the maximum input voltage rating for the NCP583XV31T2G?
The NCP583XV31T2G has an absolute maximum input voltage (VIN) of 6.5 V, with recommended operating range specified as 1.7–6.0 V. Exceeding 6.5 V risks permanent damage. For reliable operation in USB-powered or multi-cell battery systems, keep input within this limit and use appropriate input filtering.
Does the NCP583XV31T2G require an external output capacitor, and what value is recommended?
Yes, the NCP583XV31T2G requires an external ceramic output capacitor. The datasheet specifies 1.0 µF as the recommended value for stability, placed close to the Vout pin. A minimum 0.1 µF ceramic capacitor is also advised for high-frequency transient suppression, especially in noise-sensitive analog applications.
How does the enable (CE) pin function on the NCP583XV31T2G?
The CE pin on the NCP583XV31T2G is active-high: applying ≥1.2 V enables regulation, while ≤0.3 V places the device in shutdown mode with 0.1 µA typical current draw. The pin tolerates up to 6.5 V and has no internal pull-up or pull-down-external logic or MCU GPIO must drive it directly.
What is the thermal resistance (RJA) of the NCP583XV31T2G in its SOT-563 package?
The NCP583XV31T2G in SOT-563 package has a junction-to-ambient thermal resistance (RJA) of 200°C/W, measured under standard JEDEC JESD51-7 conditions. This value assumes minimal PCB copper; adding thermal vias and a 1-inch² copper pour can reduce effective RJA by ~30–40% in production layouts.
Is the NCP583XV31T2G compatible with lead-free reflow soldering processes?
Yes, the NCP583XV31T2G is Pb-free and RoHS-compliant, qualified for standard lead-free reflow profiles including peak temperatures up to 260°C. Its SOT-563 package meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life without dry pack requirements.
