Product details
Overview
NCP563SQ25T1 from onsemi is a fixed-output, low-dropout linear regulator (LDO) designed for battery-powered portable electronics. It delivers 2.5 V output at up to 80 mA with ultra-low 2.5 µA quiescent current, 2.0% output voltage accuracy, and dropout voltage as low as 230 mV at 80 mA - enabling extended runtime in handheld instruments and camcorders.
For engineers reviewing the NCP563SQ25T1 datasheet, pinout, applications, or equivalent options, key selection criteria include its SC82-AB package footprint, absence of enable functionality (N/C pin), ceramic capacitor compatibility (≥0.1 µF), and −40 °C to +85 °C operating range for embedded portable designs.
Technical Context
The NCP563SQ25T1 integrates a PMOS pass transistor, precision voltage reference, error amplifier, and thermal/overcurrent protection - all in a micro-miniature SC82-AB package. Unlike the NCP562 variant, it lacks an enable input; Pin 4 is internally unconnected (N/C), simplifying control logic but removing ON/OFF sequencing capability.
It operates with input voltages from 2.8 V to 6.0 V and maintains regulation down to 230 mV dropout at full 80 mA load across temperature. Its stability with low-ESR ceramic capacitors (0.1 µF minimum) and ±100 ppm/°C output voltage temperature coefficient support precision low-power analog and digital rail generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2.0% - ensures stable power for 2.5 V logic, sensors, or RF front-end biasing without external feedback. |
| Max Output Current | 80 mA - sufficient for low-power microcontrollers, display drivers, or audio codecs in space-constrained portable devices. |
| Quiescent Current | 2.5 µA typical - minimizes battery drain during standby, critical for multi-year operation in coin-cell–powered instrumentation. |
| Dropout Voltage | 230 mV at 80 mA (25 °C) - enables regulation from 2.73 V input, maximizing usable battery voltage range in single-cell Li-ion or alkaline systems. |
| Input Voltage Range | 2.8 V to 6.0 V - supports direct connection to single-cell Li-ion (3.0–4.2 V), two-cell alkaline (2.8–3.6 V), or regulated 5 V rails. |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial and consumer portable equipment deployed in variable ambient conditions. |
| Output Capacitor | ≥0.1 µF ceramic - eliminates need for tantalum or electrolytic capacitors, reducing BOM cost and board area while improving reliability. |
Pinout & Package
Package: SC82-AB (Case 419C), surface-mount, 4-pin micro-miniature package (2.2 mm × 1.35 mm × 0.95 mm). RoHS-compliant, Pb-free, with moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power supply ground reference - must be connected to low-impedance PCB ground plane to ensure noise immunity and thermal performance. |
| 2 | Vin | Positive input supply - accepts 2.8–6.0 V; requires local 1.0 µF decoupling capacitor placed adjacent to pin. |
| 3 | Vout | Regulated 2.5 V output - drives load directly; output capacitor ≥0.1 µF must be placed within 2 mm of this pin. |
| 4 | N/C | No internal connection - left floating or tied to GND per layout best practice; not usable for enable or feedback. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5 µA typical - extends battery life in always-on monitoring circuits without sacrificing regulation integrity. |
| Low dropout with PMOS pass device | 230 mV @ 80 mA - preserves headroom for deep-discharge battery operation while maintaining tight output tolerance. |
| High output accuracy | ±2.0% over temperature and load - eliminates need for post-regulation trimming in precision analog signal chains. |
| Stable with ceramic capacitors | 0.1 µF minimum output capacitance - reduces component count, size, and cost versus traditional LDOs requiring high-ESR tantalum. |
| Integrated protection | Thermal shutdown and current limiting - prevents damage during overload or poor heatsinking without external circuitry. |
Applications
| Handheld Medical Sensors | Digital Camera Sensor Bias Rails |
|---|---|
|

IC Role / Device Role / Timing Role: Supplies regulated 2.5 V to MCU VDD_IO and internal regulators, enabling mixed-voltage operation. Use Value: Enables <1 µA system sleep current when MCU enters deep-sleep mode; no enable pin required due to MCU-controlled power sequencing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2502E/MB | 250 mA output, 1.6 µA IQ, SOT-23-3 package - higher current but no N/C pin; requires different footprint and layout. | Supports higher-current peripherals (e.g., Bluetooth modules); unsuitable where SC82-AB size constraint is absolute. | Select if >80 mA load or smaller quiescent current is prioritized over identical form factor. |
| TPS78025QDSERQ1 | Automotive-grade (AEC-Q100), 150 mA, 500 nA IQ, enable pin, WSON-6 package - includes active-low enable and tighter temp range (−40 °C to +125 °C). | Required for automotive infotainment or ADAS subsystems needing functional safety compliance and wider junction temperature margin. | Select only for automotive applications demanding PPAP, AEC-Q100 qualification, and enable control - not drop-in compatible. |
Compared with MCP1700T-2502E/MB and TPS78025QDSERQ1, the NCP563SQ25T1 offers optimal balance of ultra-low IQ, minimal footprint, and cost for consumer portable electronics - trading off enable functionality and higher current for strict size and battery-life requirements.

FAQ
What is the maximum input voltage rating for the NCP563SQ25T1?
The NCP563SQ25T1 has a maximum input voltage rating of 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage may cause permanent damage. For reliable long-term performance, design input rails to remain ≤6.0 V under all conditions including transient spikes and ripple.
Does the NCP563SQ25T1 include an enable function?
No, the NCP563SQ25T1 does not include an enable function. Pin 4 is designated N/C (no internal connection), distinguishing it from the NCP562 series which uses Pin 4 as an active enable input. System-level ON/OFF control must be implemented externally, such as via input power switching.
What is the minimum output capacitor required for stable operation of the NCP563SQ25T1?
The NCP563SQ25T1 requires a minimum output capacitor of 0.1 µF ceramic. This value ensures stability across all operating conditions and load currents up to 80 mA. 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 NCP563SQ25T1 at 80 mA and 25 °C?
At 80 mA load and 25 °C, the NCP563SQ25T1 exhibits a typical dropout voltage of 230 mV. This means the device maintains 2.5 V output regulation as long as Vin remains ≥2.73 V. Dropout increases slightly at temperature extremes and higher loads, remaining ≤400 mV across −40 °C to +85 °C.
Is the NCP563SQ25T1 suitable for automotive applications?
The NCP563SQ25T1 is not automotive-qualified. It operates over −40 °C to +85 °C but lacks AEC-Q100 certification and PPAP capability. For automotive use, select the NCV563SQ25T1G variant (discontinued per datasheet Rev. 16) or consider alternatives like the TPS78025QDSERQ1, which is explicitly AEC-Q100 qualified.
