Product details
Overview
NCP563SQ30T1G from onsemi is a fixed-output, low-dropout linear regulator (LDO) designed for battery-powered portable electronics. It delivers 3.0 V ±2.0% output at up to 80 mA with ultra-low 2.5 µA quiescent current, 200 mV dropout at 80 mA, and operates across −40 °C to +85 °C ambient temperature - ideal for camcorders and handheld instrumentation requiring stable low-power voltage regulation.
For engineers reviewing the NCP563SQ30T1G datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed 80 mA load capability, SC82-AB package compatibility, absence of enable functionality (N/C pin), ceramic capacitor stability down to 0.1 µF, and thermal shutdown protection at ~160 °C.
Technical Context
The NCP563SQ30T1G implements a PMOS pass transistor architecture enabling low dropout and minimal ground current variation under load. Its internal circuitry includes a precision voltage reference, error amplifier, current limit, and thermal shutdown - but excludes enable control logic, as Pin 4 is explicitly designated No Connection (N/C).
This variant belongs to the NCP563 family, differentiated from the NCP562 by omission of the Enable pin and corresponding input threshold circuitry. It requires only 0.1 µF ceramic output capacitance for stability and exhibits 100 µVRMS output noise (100 Hz–100 kHz) at 3.0 V output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V ±2.0% - tightly regulated rail for microcontrollers or sensors requiring stable 3.0 V supply. |
| Max Output Current | 80 mA - sufficient for low-power MCU cores, RF transceivers, or analog front-ends in portable devices. |
| Quiescent Current | 2.5 µA typical - enables multi-year battery life in always-on monitoring applications. |
| Dropout Voltage | 200 mV at 80 mA - allows operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (3.0 V nominal) sources. |
| Operating Temp | −40 °C to +85 °C - supports industrial and consumer portable equipment deployment. |
| Output Noise | 100 µVRMS (100 Hz–100 kHz) - suitable for noise-sensitive analog circuits like ADC references or audio preamps. |
| Input Voltage Range | Up to 6.0 V - accommodates input ripple and transient surges without damage or regulation loss. |
Pinout & Package
The NCP563SQ30T1G is housed in the SC82-AB (Case 419C) surface-mount package: 1.8–2.2 mm × 1.15–1.35 mm × 0.8–1.1 mm, 4-pin, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power supply return path; must be low-impedance to minimize noise coupling and ensure regulation accuracy. |
| 2 | Vin | Positive input supply connection; accepts up to 6.0 V DC with ≤20 mV line regulation over 1.5–4.4 V input range. |
| 3 | Vout | Regulated 3.0 V output; requires ≥0.1 µF ceramic capacitor for stability and transient response. |
| 4 | N/C | No internal connection - must remain unconnected; not usable as enable, feedback, or bypass terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5 µA typical - extends battery runtime in always-on IoT sensors and wearables. |
| Low minimum output capacitance | 0.1 µF ceramic - reduces BOM cost and PCB area vs. traditional LDOs requiring ≥1 µF tantalum. |
| Thermal shutdown protection | Activates at ~160 °C junction temperature - prevents catastrophic failure during overload or poor heatsinking. |
| High output voltage accuracy | ±2.0% over temperature and load - eliminates need for post-regulation trimming in precision analog subsystems. |
| Stable with low-ESR capacitors | Supports ESR from near-zero to 10 Ω - compatible with modern ceramic MLCCs without external compensation. |
Applications

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/MB | 3.0 V output, 250 mA max, 1.6 µA IQ, SOT-23-3 package (3-pin, no GND pin exposed) | Higher output current but larger footprint; lacks thermal shutdown and current limit protection | Select when higher load current is needed and thermal robustness is secondary |
| TPS7A0530PDBVR | 3.0 V output, 200 mA max, 25 µA IQ, SOT-23-5 package with enable pin | Includes active-high enable and higher quiescent current; requires 1 µF min output cap | Select when system-level power sequencing or deeper sleep modes are required |
Compared with MCP1700T-3002E/MB and TPS7A0530PDBVR, the NCP563SQ30T1G offers superior thermal protection and lower quiescent current in a smaller SC82-AB footprint, but trades off enable functionality and maximum output current - making it optimal for space-constrained, always-on, thermally sensitive applications where simplicity and ultra-low IQ dominate.

FAQ
What is the maximum input voltage rating for the NCP563SQ30T1G?
The NCP563SQ30T1G has an absolute maximum input voltage of 6.0 V, as specified in the Maximum Ratings table. Exceeding this value may cause permanent damage. For reliable operation, the recommended input range is 3.2 V to 6.0 V to maintain regulation while staying within the 200 mV dropout margin at full 80 mA load. The device includes internal protection against overvoltage stress up to this limit, but sustained operation above 6.0 V is not supported.
Does the NCP563SQ30T1G include an enable pin function?
No, the NCP563SQ30T1G does not include an enable pin function. Pin 4 is explicitly designated "N/C" (No Connection) in the datasheet's pin function description and typical application diagram. This distinguishes it from the NCP562 variant, which uses Pin 4 as an active-low Enable input. Any attempt to drive or connect Pin 4 on the NCP563SQ30T1G may compromise reliability or violate absolute maximum ratings.
What is the minimum output capacitance required for stable operation of the NCP563SQ30T1G?
The NCP563SQ30T1G requires a minimum output capacitance of 0.1 µF ceramic, as confirmed in both the datasheet's "Typical Applications" section and Electrical Characteristics notes. This low requirement enables use of small, low-cost X5R/X7R MLCCs and supports stability across a wide ESR range (near-zero to 10 Ω). Larger values (e.g., 1.0 µF) improve load transient response and noise rejection but are not mandatory for basic regulation.
Is the NCP563SQ30T1G suitable for automotive applications?
The NCP563SQ30T1G is not qualified for automotive use. It lacks AEC-Q100 qualification and PPAP capability. For automotive-grade equivalents, onsemi offers the NCV563SQ30T1G variant (marked as discontinued in latest revision), which carries the NCV prefix and meets AEC-Q100 requirements. Designers targeting automotive systems must verify qualification status directly with onsemi documentation and select NCV-prefix parts explicitly certified for automotive environments.
What thermal protection features does the NCP563SQ30T1G provide?
The NCP563SQ30T1G integrates internal thermal shutdown protection that activates at approximately 160 °C junction temperature, as stated in the Definitions section. When triggered, the regulator disables output to prevent permanent damage. Recovery is automatic once junction temperature falls below the hysteresis threshold (~140–150 °C). This feature operates independently of load or input conditions and is inherent to all NCP563 devices, including the NCP563SQ30T1G.
