Product details
Overview
NCP563SQ27T1G from onsemi is a fixed-output, low-dropout linear regulator (LDO) designed for battery-powered portable electronics. It delivers 2.7 V ±2.0% output at up to 80 mA with ultra-low quiescent current of 2.5 µA (typical), dropout voltage of 230 mV (at 80 mA), and operates across −40 °C to +85 °C ambient temperature - enabling long runtime in handheld instruments and camcorders.
For engineers reviewing the NCP563SQ27T1G datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed 2.7 V regulation accuracy, SC82-AB package compatibility, absence of enable functionality (N/C pin), and ceramic capacitor stability down to 0.1 µF.
Technical Context
The NCP563SQ27T1G uses a PMOS pass transistor architecture to achieve low dropout and high PSRR without requiring an external bypass capacitor. Its internal circuitry includes voltage reference, error amplifier, thermal shutdown, and current limit protection - all integrated into a 4-pin SC82-AB package with no enable control logic.
Unlike the NCP562 variant, the NCP563SQ27T1G replaces the Enable pin with a No-Connect (N/C) terminal, simplifying system-level power sequencing but removing active ON/OFF control. It is optimized for low-noise, low-IQ operation with 100 µVRMS output noise (100 Hz–100 kHz) and stable performance using 0.1 µF ceramic output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.7 V ±2.0% - tightly regulated supply for 2.7 V logic rails or analog sensors |
| Max Output Current | 80 mA - sufficient for microcontrollers, RF transceivers, or sensor signal chains |
| Dropout Voltage | 230 mV @ 80 mA - enables operation from 2.93 V input (e.g., single Li-ion cell near EOD) |
| Quiescent Current | 2.5 µA typical - extends battery life in always-on monitoring applications |
| Operating Temp Range | −40 °C to +85 °C - qualified for industrial and consumer portable equipment |
| Output Capacitor Min | 0.1 µF ceramic - eliminates need for large/low-ESR tantalum, reducing BOM cost and footprint |
| Thermal Shutdown | Activates at ~160 °C - protects device during sustained overload or poor PCB thermal design |
Pinout & Package
The NCP563SQ27T1G is housed in the SC82-AB (Case 419C) surface-mount package: 4-pin, 2.2 mm × 1.35 mm × 0.95 mm, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be low-impedance connection to minimize noise and dropout error |
| 2 | Vin | Input supply pin; accepts 2.93 V to 6.0 V - supports single-cell Li-ion and multi-cell alkaline/battery stacks |
| 3 | Vout | Regulated 2.7 V output; requires ≥0.1 µF ceramic decoupling placed adjacent to pin |
| 4 | N/C | No internal connection - must remain unconnected; not usable as enable or feedback |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5 µA typical - enables >1-year battery life in 10 µA average-current IoT sensors |
| Fixed 2.7 V output accuracy | ±2.0% over temp/load - eliminates need for external trimming in precision analog front-ends |
| Stable with 0.1 µF ceramic cap | No ESR requirement - reduces cost, size, and failure risk vs. tantalum-based LDOs |
| PMOS pass element | No body diode reverse conduction - prevents backfeed in multi-rail systems |
| Integrated thermal protection | Auto-shutdown at ~160 °C - avoids permanent damage during solder reflow or overcurrent fault |
Applications
| Handheld Medical Sensors | Digital Camcorder Power Rail |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2702E/TT | 2.7 V, 250 mA, 1.6 µA IQ, SOT-23-3 package - lacks N/C pin; only 3 pins | Requires PCB redesign due to different pin count and footprint; higher current capability unused in 80 mA designs | Choose if lower IQ is critical and board layout allows SOT-23-3 integration |
| NCP562SQ27T1G | 2.7 V, 80 mA, 2.5 µA IQ, SC82-AB, includes Enable pin (pin 4) | Enables active power gating; incompatible pinout due to functional Enable vs. N/C | Choose only if system requires hardware-controlled ON/OFF - not a drop-in replacement |
Compared with MCP1700T-2702E/TT, the NCP563SQ27T1G offers identical output voltage and tighter regulation (±2.0% vs. ±2.5%), but in a smaller SC82-AB package with no enable function - making it optimal for space-constrained, always-on applications where pin count and footprint are prioritized over controllability.

FAQ
What is the maximum input voltage rating for the NCP563SQ27T1G?
The NCP563SQ27T1G has a maximum input voltage rating of 6.0 V, as specified in its Absolute Maximum Ratings table. This allows safe operation from common battery sources including two alkaline cells (3.2 V), single Li-ion (4.2 V max), or regulated 5 V supplies. Exceeding 6.0 V may cause permanent damage.
Does the NCP563SQ27T1G include an enable function?
No, the NCP563SQ27T1G does not include an enable function. Pin 4 is designated N/C (No Connection), unlike the NCP562 variant which uses pin 4 as an active-low Enable input. The NCP563SQ27T1G remains continuously active when powered within its input voltage range.
What output capacitor value is required for stable operation of the NCP563SQ27T1G?
The NCP563SQ27T1G requires a minimum output capacitor of 0.1 µF ceramic. This value ensures stability across all load conditions and temperatures. Larger values (e.g., 1.0 µF) improve load transient response and noise rejection but are not mandatory for basic regulation.
What is the dropout voltage of the NCP563SQ27T1G at 80 mA output current?
The dropout voltage of the NCP563SQ27T1G is 230 mV typical at 80 mA output current and −40 °C to +85 °C ambient temperature. This means the device maintains 2.7 V regulation as long as Vin ≥ 2.93 V, enabling efficient use of aging or low-voltage battery sources.
Is the NCP563SQ27T1G RoHS-compliant and lead-free?
Yes, the NCP563SQ27T1G is RoHS-compliant and Pb-free, as confirmed in the datasheet's "Features" section and ordering information. The "G" suffix in the part number explicitly denotes lead-free packaging per JEDEC standards, and the device meets halogen-free and BFR-free requirements.
