Product details
Overview
NCP563SQ50T1G from onsemi is a fixed-output, low-dropout linear regulator (LDO) designed for battery-powered portable electronics requiring ultra-low quiescent current (2.5 µA typical), 5.0 V output voltage with ±2.0% accuracy, and operation across −40 °C to +85 °C ambient temperature. It delivers up to 80 mA output current with a dropout voltage of 140 mV at 80 mA and uses a PMOS pass transistor in SC82-AB (SC70-4) package.
For engineers reviewing the NCP563SQ50T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its 5.0 V fixed output, 2.5 µA quiescent current, SC82-AB footprint compatibility, absence of enable functionality (N/C pin), and suitability for space-constrained, low-power instrumentation and imaging devices.
Technical Context
The NCP563SQ50T1G implements a PMOS-based LDO architecture with internal voltage reference, error amplifier, and thermal/overcurrent protection. It requires only a 0.1 µF ceramic output capacitor and operates stably without ESR constraints - unlike many older LDOs.
No enable control is integrated: Pin 4 is explicitly marked "N/C" (no internal connection), distinguishing it from the NCP562 series. Its dropout voltage remains ≤140 mV at full 80 mA load and 25 °C, and output voltage drift is limited to ±100 ppm/°C over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2.0% - ensures stable supply for 5 V logic or analog circuitry without external feedback. |
| Quiescent Current | 2.5 µA typical - enables multi-year battery life in always-on sensor or standby subsystems. |
| Max Output Current | 80 mA - sufficient for microcontrollers, sensors, or small displays in portable equipment. |
| Dropout Voltage | 140 mV at 80 mA - allows regulation down to Vin = 5.14 V, maximizing usable battery range. |
| Operating Temp | −40 °C to +85 °C - supports industrial and consumer portable applications without derating. |
| Input Voltage Range | Up to 6.0 V - compatible with single Li-ion (4.2 V max), two alkaline (3.2 V), or regulated 5 V rails. |
| Output Noise | 100 µVRMS (100 Hz–100 kHz) - low enough for noise-sensitive analog signal chains. |
Pinout & Package
The NCP563SQ50T1G is housed in the SC82-AB (SC70-4) surface-mount package - a 1.9 mm × 1.3 mm × 0.95 mm micro-miniature outline with 0.65 mm pin pitch and Pb-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be low-impedance connection to minimize noise and thermal rise. |
| 2 | Vin | Input supply pin; accepts up to 6.0 V DC; requires local 1.0 µF decoupling capacitor. |
| 3 | Vout | Regulated 5.0 V output; minimum 0.1 µF ceramic capacitor required for stability. |
| 4 | N/C | No internal connection - must be left floating or tied to GND per layout best practice; not usable as enable or feedback. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 2.5 µA typical - reduces standby power loss by >95% vs. standard LDOs, critical for coin-cell or energy-harvesting systems. |
| Capacitor flexibility | Stable with 0.1 µF ceramic output cap - eliminates need for costly tantalum or high-ESR capacitors. |
| Thermal shutdown | Activates at ~160 °C junction - protects against PCB overheating during sustained overload or poor heatsinking. |
| Pb-free & RoHS | Halogen-free/BFR-free construction - meets global environmental compliance requirements for consumer and industrial products. |
| Output accuracy | ±2.0% over temp and load - ensures reliable operation of 5 V peripherals without margining or calibration. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-5002E/TT | 2.3 µA IQ, same 5.0 V output, SOT-23-3 package (3-pin, no N/C) | Requires external bypass cap; lacks thermal shutdown; lower max current (250 mA) | Preferred where higher output current or simpler 3-pin layout is needed, but thermal safety margin is reduced. |
| TPS70650DBVR | 4.5 µA IQ, 5.0 V, SOT-23-5 with active-low enable and thermal foldback | Includes enable control and enhanced thermal protection; larger footprint and higher IQ | Chosen when system-level power sequencing or robust fault handling is required, accepting 1.8× higher quiescent draw. |
Compared with NCP563SQ50T1G, MCP1700T-5002E/TT offers higher current and smaller IQ but no thermal shutdown, while TPS70650DBVR adds enable and safety features at the cost of increased IQ and board area - making NCP563SQ50T1G optimal for space- and battery-limited applications where simplicity and ultra-low standby power are primary.

FAQ
What is the maximum input voltage rating for the NCP563SQ50T1G?
The NCP563SQ50T1G has an absolute maximum input voltage of 6.0 V, as specified in the Maximum Ratings table. Exceeding this voltage may cause permanent damage. For reliable operation, Vin should remain ≤6.0 V under all conditions including transients, and is typically operated between 5.14 V (to maintain regulation at 80 mA load) and 6.0 V.
Does the NCP563SQ50T1G include an enable pin?
No, the NCP563SQ50T1G does not include an enable function. Pin 4 is designated "N/C" (no internal connection) per the datasheet pin function description and top-view marking diagram. This distinguishes it from the NCP562 series, which uses Pin 4 as Enable. The NCP563SQ50T1G is always-on when powered within specification.
What output capacitor value is required for stable operation of the NCP563SQ50T1G?
The NCP563SQ50T1G requires a minimum output capacitor of 0.1 µF ceramic, as confirmed in both the datasheet introduction and Applications Information section. Larger values (e.g., 1.0 µF) improve load transient response and noise rejection but are not mandatory for stability. Tantalum capacitors are also acceptable, provided ESR remains within 0–10 Ω.
Is the NCP563SQ50T1G still in active production?
No - the NCP563SQ50T1G is officially marked as discontinued per the February 2026 revision of the onsemi datasheet (page 7, Note 5). However, Aetrix Electronics maintains legacy inventory and provides lifecycle coordination support, including last-time-buy planning and cross-reference guidance for qualified replacements.
What is the thermal shutdown threshold for the NCP563SQ50T1G?
The NCP563SQ50T1G incorporates internal thermal protection that activates at approximately 160 °C junction temperature, as stated in the Definitions section of the datasheet. Once triggered, the regulator shuts down to prevent damage; it resumes normal operation after cooling below the hysteresis threshold (typically ~140 °C).
