Product details
Overview
NCP563SQ50T1 from onsemi is a fixed-output, low-dropout linear voltage regulator delivering 5.0 V at up to 80 mA with ultra-low quiescent current (2.5 µA typical), housed in the SC82-AB (SC70-4) surface-mount package. It features PMOS pass transistor architecture, ±2.0% output voltage accuracy over temperature, and operates across −40 °C to +85 °C ambient for battery-powered instrumentation and portable electronics.
For engineers reviewing the NCP563SQ50T1 datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage (140 mV at 80 mA), thermal shutdown protection, compatibility with 0.1 µF ceramic output capacitors, and absence of enable functionality-distinguishing it from the NCP562 series.
Technical Context
The NCP563SQ50T1 implements a PMOS-based LDO architecture with internal voltage reference, error amplifier, and thermal/overcurrent protection circuits. It requires no external enable control and uses a no-connect (N/C) pin instead of an enable input-unlike the NCP562 variant.
Designed for stability with minimal 0.1 µF ceramic output capacitance, it achieves 100 µVRMS output noise (100 Hz–100 kHz) and maintains regulation under load transients up to 80 mA while exhibiting 20 mV load regulation and 10–20 mV line regulation across its input range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2.0% - tightly regulated nominal rail for microcontroller I/O or sensor biasing. |
| Max Output Current | 80 mA - sufficient for low-power logic, RF modules, or analog front-ends without thermal derating at room ambient. |
| Dropout Voltage | 140 mV @ 80 mA - enables operation down to Vin = 5.14 V, critical for single-cell Li-ion or 5 V rail margining. |
| Quiescent Current | 2.5 µA typical - extends battery life in always-on monitoring systems with infrequent wake-up cycles. |
| Operating Temp Range | −40 °C to +85 °C - validated for industrial and consumer portable equipment environments. |
| Output Capacitor Min | 0.1 µF ceramic - eliminates need for bulk tantalum; supports compact PCB layout and fast transient response. |
| Thermal Shutdown | Activates at ~160 °C - protects against sustained overload or poor heatsinking in sealed enclosures. |
Pinout & Package
Package: SC82-AB (SC70-4), 1.8 mm × 1.15 mm × 0.9 mm body, Pb-free, RoHS-compliant surface-mount package per CASE 419C-02.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be low-impedance connection to minimize noise coupling and ensure regulation accuracy. |
| 2 | Vin | Input supply pin; accepts 5.14 V to 6.0 V (min/max per dropout and absolute max ratings). |
| 3 | Vout | Regulated 5.0 V output; connects directly to load and 0.1 µF ceramic decoupling capacitor. |
| 4 | N/C | No internal connection; must remain unconnected-floating or tied to GND/Vin degrades performance or causes malfunction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 2.5 µA typical enables >1-year battery life in 10 µA average-current IoT sensors. |
| PMOS Pass Device | Eliminates need for external bypass capacitor; supports stable operation with zero-ESR ceramic output caps. |
| ±2.0% Output Accuracy | Guarantees 4.90–5.10 V output across temp/load, meeting ADC reference and logic-level interface requirements. |
| Thermal & Current Limit | Integrated protection prevents latch-up or destruction during short-circuit or high-ambient conditions. |
| 0.1 µF Ceramic Stability | Reduces BOM count and board area vs. traditional LDOs requiring ≥1 µF tantalum or aluminum electrolytic. |
Applications
| Portable Medical Sensors | Industrial Handheld Meters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-IQ LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-5002E/TT | 2.3 µA IQ, 250 mA output, SOT-23-3 package, no N/C pin; requires 1 µF min output cap. | Higher current capability but larger footprint and stricter capacitor requirement limits miniaturization. | Select when >80 mA load or SOT-23 assembly infrastructure exists; avoid if SC70-4 space constraint or 0.1 µF cap is mandatory. |
| TPS70650DBVR | 4.5 µA IQ, 150 mA output, enable pin, SOT-23-5 package, 0.1 µF stable, ±1% accuracy. | Includes enable control and tighter accuracy but consumes more quiescent current and adds pin complexity. | Choose when system-level ON/OFF sequencing is required or ±1% regulation is critical; not suitable for ultra-low-IQ priority designs. |
Compared with NCP563SQ50T1, MCP1700T-5002E/TT offers higher output current but sacrifices SC70-4 size and 0.1 µF capacitor support, while TPS70650DBVR adds enable functionality and tighter accuracy at the cost of 80% higher quiescent current-making NCP563SQ50T1 optimal for space-constrained, always-on 5 V rail applications where minimal IQ and minimal BOM are primary drivers.

FAQ
What is the maximum input voltage rating for NCP563SQ50T1?
The absolute maximum input voltage for NCP563SQ50T1 is 6.0 V, as specified in the Maximum Ratings table. Exceeding this value risks permanent damage. For reliable operation at full 80 mA load, minimum input is 5.14 V (5.0 V + 140 mV dropout); operation between 5.14 V and 6.0 V ensures regulation within specifications across temperature and load conditions.
Does NCP563SQ50T1 include an enable pin?
No, NCP563SQ50T1 does not include an enable pin. Pin 4 is designated N/C (no internal connection), distinguishing it from the NCP562 series which uses Pin 4 as an active-enable input. Systems requiring ON/OFF control must use external FET switching on the input rail or select the NCP562 variant instead.
What output capacitor value is required for stable operation of NCP563SQ50T1?
NCP563SQ50T1 is stable with a minimum 0.1 µF ceramic output capacitor, as confirmed in the datasheet's Applications Information section. Larger values (e.g., 1.0 µF) improve load transient response and noise rejection but are not required for basic regulation. Tantalum capacitors are also acceptable, though ceramic is preferred for size and ESR flexibility.
Is NCP563SQ50T1 still in active production?
No, NCP563SQ50T1 is marked as discontinued per onsemi's official datasheet revision 16 (February 2026). However, Aetrix Electronics maintains legacy inventory and provides lifecycle coordination support-including last-time-buy planning and cross-reference guidance-to ensure continuity for existing designs.
What is the thermal shutdown threshold for NCP563SQ50T1?
NCP563SQ50T1 activates thermal shutdown at approximately 160 °C junction temperature, as stated in the Definitions section of the datasheet. Once triggered, the device disables output until junction temperature falls below the hysteresis threshold (~140 °C), protecting against sustained overload or inadequate PCB thermal relief in enclosed assemblies.
