Product details
Overview
NCP583XV30T2G from onsemi is an ultra-low quiescent current (1.0 µA typical), 3.0 V fixed-output CMOS low-dropout regulator in SOT-563 package, delivering up to 150 mA output current with 2% output voltage accuracy and 250 mV dropout at full load - designed for battery-powered portable equipment requiring long runtime and stable voltage regulation.
For engineers reviewing the NCP583XV30T2G datasheet, pinout, applications, or equivalent options, key selection considerations include its 0.1 µA shutdown current, ±100 ppm/°C temperature coefficient, enable-controlled operation, and compatibility with 0.1 µF ceramic output capacitance.
Technical Context
The NCP583XV30T2G integrates a precision bandgap reference, error amplifier, and PMOS pass transistor in a CMOS architecture enabling ultra-low Iq without compromising transient response. Its enable input (CE) provides active-high logic control with 1.2 V to 6.0 V threshold range, supporting direct microcontroller interfacing.
It features foldback current limiting and thermal shutdown protection, operates across −40°C to +85°C ambient, and maintains regulation with input voltages from 1.7 V to 6.0 V - making it suitable for single-cell Li-ion, multi-cell alkaline, or regulated intermediate rail applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% - ensures stable power for 3.0 V logic, sensors, or RF modules without external feedback components. |
| Max Output Current | 150 mA - sufficient to power microcontrollers, BLE radios, or display drivers in compact portable systems. |
| Dropout Voltage | 250 mV at 150 mA - enables operation down to ~3.25 V input, extending usable battery life in single-cell Li-ion (3.0–4.2 V) applications. |
| Quiescent Current | 1.0 µA typical - minimizes standby power loss, critical for always-on IoT sensors or remote controls with multi-year battery life. |
| Shutdown Current | 0.1 µA typical - reduces system-level leakage when disabled via CE pin, preserving battery during deep sleep modes. |
| Line Regulation | 0.05%/V - maintains tight output stability despite input rail sag (e.g., battery discharge), reducing need for post-regulation filtering. |
| Temp Coefficient | ±100 ppm/°C - limits output drift to ±0.025 V over −40°C to +85°C, supporting precision analog front-ends without calibration. |
Pinout & Package
SOT−563 (Case 463A) - 6-pin, 1.6 mm × 1.2 mm × 0.6 mm surface-mount package with two ground pins (Pins 2 and 5) and one no-connect terminal (Pin 4), optimized for high-density PCB layouts and thermal performance (RJA = 200°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vin | Input supply connection - accepts 1.7 V to 6.0 V; requires 1.0 µF ceramic decoupling to GND per datasheet recommendation. |
| 2 | GND | Power ground - primary return path for load current; must be connected to low-impedance ground plane. |
| 3 | Vout | Regulated 3.0 V output - drives load directly; requires 0.1 µF ceramic capacitor placed adjacent to pin for stability. |
| 4 | NC | No connect - electrically isolated; no PCB trace or solder mask opening required. |
| 5 | GND | Secondary ground - improves thermal dissipation and reduces ground bounce in high-transient-current scenarios. |
| 6 | CE | Active-high chip enable - pulls high (>1.2 V) to activate regulator; tied low (<0.3 V) to enter 0.1 µA shutdown mode. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 250 mV @ 150 mA enables use with depleting batteries while maintaining 3.0 V output - extends operational time in coin-cell or Li-ion systems. |
| 1.0 µA quiescent current | Reduces standby power to <3 nW per volt of input - critical for energy-harvesting or battery-backed real-time clocks. |
| 0.1 µA shutdown current | Allows complete system power gating without sacrificing fast wake-up (<10 µs typical turn-on time per datasheet curves). |
| ±2% output accuracy | Eliminates need for external trimming or calibration in cost-sensitive consumer electronics like wearables and remote controls. |
| Foldback current limit | Protects internal pass device during short-circuit events by reducing output current as Vout collapses - prevents thermal runaway. |
Applications
| Portable Medical Sensors | Wireless Remote Controls |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 1.6 µA Iq, 600 mV dropout @ 250 mA, SOT-23-5 package | Higher dropout limits usable input range; larger footprint than SOT-563 | Prefer when higher output current (250 mA) is needed and board space permits larger package. |
| Torex XC6206P302MR-G | 1.0 µA Iq, 200 mV dropout @ 100 mA, SOT-25 package | Lower max current (100 mA); no dedicated CE pin - uses VIN-controlled enable | Prefer when strict 100 mA limit is acceptable and simplified enable logic (no separate CE trace) is desired. |
Compared with MCP1700T-3002E/TT and XC6206P302MR-G, the NCP583XV30T2G offers the lowest combination of dropout (250 mV @ 150 mA) and package density (SOT-563), while retaining independent CE control - making it optimal for space- and battery-life-constrained portable designs requiring 150 mA at 3.0 V.

FAQ
What is the maximum input voltage rating for the NCP583XV30T2G?
The NCP583XV30T2G has a maximum input voltage rating of 6.0 V under normal operating conditions, as specified in the Electrical Characteristics table. Absolute maximum ratings allow up to 6.5 V on Vin and CE pins, but sustained operation above 6.0 V may impact reliability and is not recommended for production designs using the NCP583XV30T2G.
Does the NCP583XV30T2G require an external capacitor on the output pin?
Yes, the NCP583XV30T2G requires a 0.1 µF ceramic capacitor on the Vout pin for stability, as confirmed in the Application Information section. A 1.0 µF ceramic capacitor is recommended on Vin, but the output capacitor is mandatory - omitting it risks oscillation or poor transient response in the NCP583XV30T2G.
Is the NCP583XV30T2G pin-compatible with other variants in the NCP583 family?
No - the NCP583XV30T2G uses the SOT-563 package (6-pin), while SC-82AB variants (e.g., NCP583SQ30T1G) use a 4-pin package. Pin count, pinout, and package dimensions differ; therefore, the NCP583XV30T2G is not pin-compatible with SQ-suffix parts, and PCB layout changes are required when substituting.
What is the typical enable threshold voltage for the CE pin of the NCP583XV30T2G?
The NCP583XV30T2G CE pin has a typical high-threshold voltage of 1.2 V and low-threshold of 0.3 V, as defined in the Electrical Characteristics table. This allows direct interfacing with 1.8 V or 3.3 V GPIOs without level-shifting - the NCP583XV30T2G turns on reliably when CE ≥1.2 V and shuts down fully when CE ≤0.3 V.
How does the NCP583XV30T2G handle thermal overload conditions?
The NCP583XV30T2G incorporates thermal shutdown protection that disables the output when junction temperature exceeds approximately 125°C. Recovery is automatic once temperature falls below the hysteresis threshold. This safeguard prevents permanent damage during sustained overload or poor PCB heat sinking - a core safety feature built into the NCP583XV30T2G.
