Product details
Overview
NCP563SQ25T1G from onsemi is a fixed-output, low-dropout linear voltage regulator delivering 2.5 V at up to 80 mA with ultra-low 2.5 µA typical 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 - ideal for battery-powered instrumentation requiring stable low-power bias.
For engineers reviewing the NCP563SQ25T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 80 mA (250 mV typ.), ±2.0% output accuracy, 0.1 µF minimum ceramic output capacitance, and absence of enable functionality compared to NCP562 variants.
Technical Context
The NCP563SQ25T1G uses a PMOS pass transistor architecture enabling low dropout and zero reverse-current flow. Its internal circuitry includes a precision voltage reference, error amplifier, and protection blocks for thermal shutdown and current limiting - all optimized for minimal ground current under no-load conditions.
Unlike the NCP562 series, the NCP563 variant omits the Enable pin and replaces it with a No-Connect (N/C) terminal, simplifying control logic but removing active ON/OFF capability. It requires only 0.1 µF ceramic output capacitance and remains stable across wide temperature and load ranges without ESR constraints.
Key Specifications

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/TT | 250 mA rated output, 1.6 µA IQ, SOT-23-3 package - higher current but no N/C pin; lacks thermal shutdown flag. | Supports higher load currents; requires different footprint and layout; no thermal fault reporting. | Select when >80 mA load or smaller solution size is required; verify thermal margin at full load. |
| TPS70625DBVR | 200 mA output, 1.7 µA IQ, SOT-23-5 with enable - adds active control but increases pin count and complexity. | Enables power sequencing and deep-sleep modes; incompatible pinout and control logic vs. NCP563SQ25T1G. | Choose when system-level power management requires enable signaling; not drop-in compatible. |
Compared with MCP1700T-2502E/TT and TPS70625DBVR, the NCP563SQ25T1G offers optimal balance of ultra-low IQ, compact SC70-4 footprint, and integrated protection - ideal where space, battery life, and simplicity outweigh need for higher current or enable control.

FAQ
What is the maximum input voltage rating for the NCP563SQ25T1G?
The NCP563SQ25T1G has an absolute maximum input voltage of 6.0 V. Operation above this level risks permanent damage. For reliable long-term performance, maintain Vin ≤ 6.0 V across all operating conditions including transient spikes - especially important in battery-fed systems where charger overshoot may occur.
Does the NCP563SQ25T1G include an enable function?
No, the NCP563SQ25T1G does not include an enable function. Pin 4 is designated N/C (No Connection), unlike the NCP562 series which uses Pin 4 as an active Enable input. To achieve ON/OFF control with NCP563SQ25T1G, external switching of the input supply or use of a discrete MOSFET is required.
What is the minimum output capacitor required for stability with the NCP563SQ25T1G?
The NCP563SQ25T1G requires a minimum output capacitor of 0.1 µF ceramic. This value ensures loop stability across all loads and temperatures. Larger values (e.g., 1.0 µF) improve load transient response and noise rejection but are not necessary for basic regulation. Avoid electrolytic or high-ESR capacitors unless explicitly validated.
How accurate is the output voltage of the NCP563SQ25T1G over temperature and load?
The NCP563SQ25T1G guarantees ±2.0% output voltage accuracy over the full operating range (−40 °C to +85 °C ambient, 1 mA to 80 mA load). This includes initial tolerance, line regulation (≤20 mV), and load regulation (≤40 mV), making it suitable for applications demanding consistent bias without post-production calibration.
Is the NCP563SQ25T1G suitable for automotive applications?
The NCP563SQ25T1G is not AEC-Q100 qualified. For automotive use, onsemi offers the NCV563SQ25T1G variant (discontinued per datasheet Rev. 16), or alternatively the NCV562 series with enable and automotive qualification. The NCP563SQ25T1G is intended for commercial and industrial applications only.
