Product details
Overview
NCP563SQ28T1G from onsemi is a fixed-output, low-dropout linear voltage regulator delivering 2.8 V at up to 80 mA with 2.5 µA typical quiescent current, ±2.0% output voltage accuracy, and dropout voltage of 230 mV at 80 mA - designed for battery-powered portable electronics requiring ultra-low power consumption and stable low-voltage rail generation.
For engineers reviewing the NCP563SQ28T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its SC82-AB package footprint, absence of enable functionality (N/C pin), 0.1 µF minimum ceramic output capacitance requirement, and thermal performance in compact handheld designs.
Technical Context
The NCP563SQ28T1G uses a PMOS pass transistor architecture enabling low dropout and ultra-low ground current. It integrates internal voltage reference, error amplifier, current limit, and thermal shutdown protection - all operating without external compensation.
No enable control is implemented; Pin 4 is internally unconnected (N/C). The device achieves stability with 0.1 µF–1.0 µF ceramic output capacitors and requires no minimum load current, supporting high-efficiency operation across −40 °C to +85 °C ambient temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.8 V ±2.0% - tightly regulated rail for 2.8 V logic or analog subsystems |
| Max Output Current | 80 mA - sufficient for microcontrollers, sensors, or RF front-end biasing |
| 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 down to 3.03 V input for 2.8 V output |
| Input Voltage Range | Up to 6.0 V - compatible with single Li-ion, two alkaline, or regulated 5 V supplies |
| Operating Temp | −40 °C to +85 °C - qualified for industrial and consumer portable environments |
| Output Capacitor | Min 0.1 µF ceramic - enables space-constrained PCB layouts with low-ESR stability |
Pinout & Package
The NCP563SQ28T1G is housed in the SC82-AB (Case 419C) surface-mount package: 2.2 mm × 1.35 mm × 0.95 mm, 4-pin, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power supply return path; must be low-impedance connection to minimize noise and thermal rise |
| 2 | Vin | Input supply pin; accepts 2.83 V to 6.0 V; requires local 1.0 µF decoupling capacitor |
| 3 | Vout | Regulated 2.8 V output; connects directly to load and 0.1 µF–1.0 µF ceramic capacitor |
| 4 | N/C | No internal connection; must remain floating - not tied to GND, Vin, or any other node |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 2.5 µA typical ground current enables >10-year battery life in 10 µA average-load applications |
| Low dropout | 230 mV at full 80 mA load allows operation from depleting single-cell batteries |
| High accuracy | ±2.0% output tolerance ensures reliable interface with 2.8 V I/O domains and ADC references |
| Thermal protection | Internal shutdown activates at ~160 °C junction temperature, preventing damage during overload or poor heatsinking |
| Ceramic capacitor compatible | Stable with 0.1 µF–1.0 µF X5R/X7R ceramics - eliminates need for larger, higher-ESR tantalum parts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-IQ LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2802E/TT | 2.8 V, 250 mA, 1.6 µA IQ, SOT-23-3 package - lacks N/C pin; only 3 pins | Higher current capability but larger footprint; no pin compatibility with SC82-AB | Select when >80 mA load or lowest possible IQ is critical; requires PCB redesign |
| TPS70628DRVR | 2.8 V, 150 mA, 1.3 µA IQ, enable pin, WSON-6 package - includes active-high EN and thermal foldback | Enables system-level power sequencing; not drop-in due to pin count, size, and function | Choose when enable control or higher current margin is required; not suitable for space-constrained SC82-AB layouts |
Compared with MCP1700T-2802E/TT and TPS70628DRVR, the NCP563SQ28T1G offers the smallest footprint (SC82-AB), precise 2.8 V output with 2.0% tolerance, and optimized 80 mA capability for ultra-compact battery-powered systems where enable functionality is unnecessary.

FAQ
What is the maximum input voltage rating for the NCP563SQ28T1G?
The NCP563SQ28T1G has an absolute maximum input voltage of 6.0 V. Exceeding this rating may cause permanent damage. For reliable operation, maintain Vin ≤ 6.0 V while ensuring sufficient headroom above 2.8 V to meet dropout requirements - e.g., ≥3.03 V for full 80 mA load. The device includes internal protection against overvoltage stress within this limit.
Does the NCP563SQ28T1G have an enable pin?
No, the NCP563SQ28T1G does not include an enable function. Pin 4 is designated N/C (no internal connection) and must remain unconnected. This distinguishes it from the NCP562 variant, which uses Pin 4 as an active-low enable input. The NCP563SQ28T1G operates continuously when valid input voltage is applied to Pin 2.
What output capacitor value is required for stable operation of the NCP563SQ28T1G?
The NCP563SQ28T1G requires a minimum output capacitor of 0.1 µF ceramic (X5R or X7R dielectric). Larger values up to 1.0 µF improve load transient response and noise rejection. Unlike older LDOs, it does not require a specific ESR range and remains stable with low-ESR ceramic capacitors - eliminating need for bulkier tantalum alternatives.
What is the dropout voltage of the NCP563SQ28T1G at 80 mA load and room temperature?
The dropout voltage of the NCP563SQ28T1G is 230 mV at 80 mA load and 25 °C. This means the device maintains regulation as long as Vin ≥ 3.03 V (2.8 V + 0.23 V). Dropout increases slightly at temperature extremes - up to 400 mV at −40 °C and 350 mV at +85 °C per datasheet Figure 7 - critical for battery end-of-life design margins.
Is the NCP563SQ28T1G suitable for automotive applications?
The NCP563SQ28T1G is not AEC-Q100 qualified. For automotive use, select the NCV563SQ28T1G variant (if available) or NCV562SQ28T1G, which carry the NCV prefix indicating automotive qualification, PPAP capability, and extended process controls. The NCP563SQ28T1G is rated for −40 °C to +85 °C ambient, matching industrial grade but lacking automotive-specific validation and change control.
