Product details
Overview
NCV563SQ15T1G from onsemi is an automotive-grade fixed-output low-dropout linear regulator delivering 1.5 V at up to 80 mA with ultra-low 2.5 µA quiescent current, ±2.0% output voltage accuracy, and operation from −40 °C to +85 °C - designed for battery-powered instrumentation requiring stable, low-power voltage regulation.
For engineers reviewing the NCV563SQ15T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage (250 mV @ 80 mA), SC82-AB package compatibility, AEC-Q100 qualification, absence of enable functionality, and ceramic capacitor support down to 0.1 µF.
Technical Context
The NCV563SQ15T1G implements a PMOS pass transistor architecture enabling low dropout and high PSRR across load and line variations. It integrates internal current limit and thermal shutdown protection, with no enable control - unlike the NCP562 variant - and operates without external bias or feedback components.
Its design targets low-noise, low-quiescent applications where input-to-output differential is constrained; the 250 mV dropout at 80 mA and ±100 ppm/°C temperature coefficient ensure stable 1.5 V output under varying thermal and load conditions in compact portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2.0% - ensures precise rail generation for 1.5 V logic or analog circuitry without external resistors. |
| Max Output Current | 80 mA - supports microcontrollers, sensors, and RF front-ends in space-constrained automotive modules. |
| Quiescent Current | 2.5 µA typical - enables multi-year battery life in always-on monitoring systems. |
| Dropout Voltage | 250 mV @ 80 mA - allows operation from 1.75 V input, critical for single-cell LiFePO₄ or dual-cell alkaline supplies. |
| Operating Temp | −40 °C to +85 °C - meets automotive cabin and industrial ambient requirements without derating. |
| Input Voltage Range | Up to 6.0 V - accommodates transient surges and unregulated battery inputs. |
| Output Capacitor | Min 0.1 µF ceramic - eliminates need for large tantalum or electrolytic capacitors, reducing board area and cost. |
Pinout & Package
NCV563SQ15T1G is housed in the SC82-AB (Case 419C) surface-mount package - a 4-pin, 2.2 mm × 1.35 mm × 0.95 mm micro-miniature leadless package optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power supply ground reference; must be connected to low-impedance PCB plane for noise immunity and thermal dissipation. |
| 2 | Vin | Positive input supply; accepts up to 6.0 V with internal overvoltage protection. |
| 3 | Vout | Regulated 1.5 V output; requires ≥0.1 µF ceramic capacitor placed adjacent to pin for stability. |
| 4 | N/C | No internal connection - left floating; not bonded or tied internally; no routing or soldering required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5 µA typical - extends battery runtime in always-on telematics and sensor nodes. |
| AEC-Q100 qualified | Automotive-grade reliability with PPAP capability - suitable for under-hood and infotainment subsystems. |
| Low-noise output | 100 µVRMS (100 Hz–100 kHz) - minimizes interference in precision ADCs and RF receivers. |
| Thermal shutdown protection | Activates at ~160 °C - prevents catastrophic failure during overload or poor heatsinking. |
| Pb-free, RoHS-compliant | Halogen-free/BFR-free construction - satisfies global environmental compliance mandates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV563SQ18T1G | Fixed 1.8 V output; otherwise identical electrical and thermal specs, same SC82-AB package and AEC-Q100 rating. | Used where system logic requires 1.8 V I/O or core voltage instead of 1.5 V. | Select when target rail voltage is 1.8 V; pinout and layout are identical - only output voltage differs. |
| NCP563SQ15T1G | Same 1.5 V output, SC82-AB package, and 2.5 µA IQ, but commercial-grade (−40 °C to +85 °C) without AEC-Q100 qualification or PPAP support. | Suitable for non-automotive industrial or consumer applications where automotive reliability is not mandated. | Choose for cost-sensitive non-automotive designs; NCV563SQ15T1G adds automotive traceability and process controls. |
Compared with NCV563SQ15T1G, NCV563SQ18T1G offers identical form-factor and reliability but shifts the output to 1.8 V, while NCP563SQ15T1G provides the same 1.5 V regulation at lower qualification cost - making the NCV variant essential for automotive Tier-1 supply chains requiring PPAP documentation and AEC-Q100 validation.

FAQ
What is the maximum input voltage rating for the NCV563SQ15T1G?
The NCV563SQ15T1G has a maximum input voltage rating of 6.0 V, as specified in its Absolute Maximum Ratings table. This allows safe operation with common battery chemistries including Li-ion (4.2 V max), LiFePO₄ (3.6 V max), and dual-cell alkaline (3.2 V fresh), plus margin for transient spikes. Exceeding 6.0 V may damage the device.
Does the NCV563SQ15T1G include an enable pin?
No, the NCV563SQ15T1G does not include an enable pin. Pin 4 is marked N/C (no internal connection). Unlike the NCP562 series, the NCP563/NCV563 family omits enable functionality - it operates continuously when valid input voltage is applied. The NCV563SQ15T1G is intended for always-on or externally switched applications.
What is the minimum output capacitor required for stable operation of the NCV563SQ15T1G?
The NCV563SQ15T1G requires a minimum output capacitor of 0.1 µF ceramic, as confirmed in the datasheet's "APPLICATIONS INFORMATION" section. Larger values improve load transient response and noise rejection, but 0.1 µF is sufficient for stability across all operating conditions - eliminating need for ESR-matching or specialized capacitor types.
Is the NCV563SQ15T1G AEC-Q100 qualified?
Yes, the NCV563SQ15T1G is AEC-Q100 qualified and PPAP capable, as explicitly stated in the datasheet's Features section and Ordering Information footnote. The "NCV" prefix denotes automotive-grade qualification, including stress testing, process control, and traceability required for Tier-1 automotive supply chains.
What is the dropout voltage of the NCV563SQ15T1G at 80 mA load current?
The dropout voltage of the NCV563SQ15T1G is 250 mV at 80 mA load current and −40 °C to +85 °C ambient temperature, measured when output drops 3.0% below nominal (i.e., 1.455 V). This value is specified in the Electrical Characteristics table under "Dropout Voltage" for the 1.5 V–1.7 V output range.
