Product details
Overview
NCP563SQ27T1 from onsemi is a fixed-output, low-dropout linear voltage regulator delivering 2.7 V at up to 80 mA with ultra-low 2.5 µA quiescent current, housed in the SC82-AB (SC70-4) package. It integrates PMOS pass transistor, thermal and current limiting, and operates across −40 °C to +85 °C ambient for battery-powered instrumentation and portable electronics.
For engineers reviewing the NCP563SQ27T1 datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 80 mA (230 mV), output accuracy (±2.0%), compatibility with 0.1 µF ceramic output capacitors, and absence of enable functionality compared to the NCP562 series.
Technical Context
The NCP563SQ27T1 implements a PMOS-based LDO architecture with internal voltage reference, error amplifier, and protection circuitry-no external enable control required. Its fixed 2.7 V output is trimmed during production to ±2.0% accuracy over temperature and load.
Designed for minimal external components, it achieves stability with ≥0.1 µF ceramic output capacitance and requires no minimum ESR. Dropout voltage remains ≤230 mV at 80 mA and −40 °C to +85 °C, enabling operation down to Vin = 2.93 V while maintaining regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.7 V ±2.0% - tightly regulated supply for 2.7 V logic or analog rails |
| Max Output Current | 80 mA - sufficient for microcontrollers, sensors, and RF front-ends in portable devices |
| Quiescent Current | 2.5 µA typical - enables multi-year battery life in always-on sensor nodes |
| Dropout Voltage | 230 mV at 80 mA - supports operation from single-cell Li-ion (3.0 V min) or two-cell alkaline |
| Input Voltage Range | Up to 6.0 V - compatible with common battery and DC-DC pre-regulator outputs |
| Operating Temp | −40 °C to +85 °C - qualified for industrial and consumer portable equipment |
| Output Capacitor | Min 0.1 µF ceramic - eliminates need for costly tantalum or high-ESR capacitors |
Pinout & Package
Package: SC82-AB (SC70-4), 1.8 mm × 1.15 mm × 0.9 mm, Pb-free, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be low-impedance connection to minimize noise and dropout variation |
| 2 | Vin | Input supply pin; accepts 2.93 V to 6.0 V; requires local 1.0 µF decoupling capacitor |
| 3 | Vout | Regulated 2.7 V output; connects directly to load and 0.1 µF–1.0 µF ceramic capacitor |
| 4 | N/C | No internal connection; must remain unconnected or floating - not tied to GND/Vin |
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 applications |
| Low-cost ceramic stability | Stable with 0.1 µF X5R/X7R MLCC - eliminates ESR constraints and lowers BOM cost |
| Fixed 2.7 V output | Factory-trimmed ±2.0% - avoids external resistor network, saves PCB area and calibration effort |
| Thermal shutdown | Activates at ~160 °C junction - protects against sustained overload or poor PCB thermal design |
| SC82-AB footprint | 0.65 mm pitch, 4-pin - enables high-density layouts in space-constrained wearables and IoT modules |

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-2702E/TT | 2.7 V, 250 mA, 1.6 µA IQ, SOT-23-3 - lacks N/C pin; different pinout (Vin-GND-Vout) | Higher current capability but larger footprint; no thermal shutdown flag | Select when >80 mA load or lower IQ is critical; verify PCB layout change for 3-pin vs. 4-pin SC82-AB |
| TPS70627DBVR | 2.7 V, 150 mA, 4.5 µA IQ, SOT-23-5 - includes enable and active-low reset, higher IQ | Supports system-level power sequencing; adds complexity for simple always-on use | Choose when enable control or power-good signaling is required; avoid if minimizing component count and IQ are top priorities |
Compared with MCP1700T-2702E/TT and TPS70627DBVR, the NCP563SQ27T1 offers optimal balance of ultra-low IQ, small SC82-AB footprint, and simplicity for fixed 2.7 V always-on loads - without requiring enable logic or sacrificing thermal protection.

FAQ
What is the maximum input voltage rating for the NCP563SQ27T1?
The NCP563SQ27T1 has an absolute maximum input voltage of 6.0 V. Exceeding this may cause permanent damage. For reliable operation, Vin should remain within 2.93 V (2.7 V + dropout) to 6.0 V, with recommended derating above 85 °C ambient per thermal limits in the datasheet.
Does the NCP563SQ27T1 include an enable pin?
No, the NCP563SQ27T1 does not include an enable pin. Pin 4 is marked N/C (no internal connection). This distinguishes it from the NCP562 series, which features an Enable pin. The NCP563SQ27T1 is designed for always-on operation without external control logic.
What output capacitor value is required for stable operation of the NCP563SQ27T1?
The NCP563SQ27T1 requires a minimum output capacitor of 0.1 µF ceramic (X5R/X7R). Larger values (up to 1.0 µF) improve load transient response and noise rejection. Unlike many LDOs, it imposes no ESR requirement, enabling use of low-cost, low-ESR MLCCs without risk of oscillation.
What is the dropout voltage of the NCP563SQ27T1 at 80 mA and 25 °C?
At 80 mA load and 25 °C, the dropout voltage of the NCP563SQ27T1 is 230 mV maximum (typical value not specified, but guaranteed ≤230 mV per Electrical Characteristics table). This means Vin must be ≥2.93 V to maintain 2.7 V output regulation under full load at room temperature.
Is the NCP563SQ27T1 suitable for automotive applications?
The NCP563SQ27T1 is not AEC-Q100 qualified. For automotive use, onsemi offers the NCV563SQ27T1G variant (NCV prefix), which is AEC-Q100 qualified and PPAP capable. The NCP563SQ27T1 is rated for −40 °C to +85 °C ambient and intended for industrial and consumer portable equipment.
