Product details
Overview
NCP563SQ15T1G from onsemi is a fixed-output, low-dropout linear regulator (LDO) designed for battery-powered portable electronics. It delivers 1.5 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 140 mV at 80 mA - enabling extended runtime in handheld instruments and camcorders.
For engineers reviewing the NCP563SQ15T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its SC82-AB package footprint, absence of enable functionality (N/C pin), compatibility with 0.1 µF ceramic output capacitors, and operation across −40 °C to +85 °C ambient temperature.
Technical Context
The NCP563SQ15T1G uses a PMOS pass transistor architecture to achieve low dropout and stable regulation without requiring high-ESR output capacitors. Its internal circuitry includes voltage reference, error amplifier, thermal shutdown, and current limit protection - all integrated into a 4-pin micro-miniature surface-mount package.
Unlike the NCP562 variant, the NCP563SQ15T1G omits the enable function: Pin 4 is designated N/C (no internal connection), simplifying control logic in always-on power rails. It supports input voltages from 1.9 V to 6.0 V and maintains regulation down to 1.64 V input when delivering 1.5 V at 80 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.5 V ±2.0% - tightly regulated rail for low-voltage microcontrollers or sensors. |
| Max Output Current | 80 mA - sufficient for single-chip subsystems like camera modules or Bluetooth LE peripherals. |
| Quiescent Current | 2.5 µA typical - enables multi-year battery life in standby-mode instrumentation. |
| Dropout Voltage | 140 mV at 80 mA - allows operation from single-cell Li-ion (3.0–4.2 V) or two-cell alkaline (2.4–3.2 V) sources. |
| Input Voltage Range | 1.9 V to 6.0 V - accommodates wide battery discharge profiles and upstream DC-DC stages. |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial and consumer portable equipment environments. |
| Output Capacitor Min. | 0.1 µF ceramic - eliminates need for bulk tantalum, reducing BOM cost and board area. |
Pinout & Package
The NCP563SQ15T1G is housed in the SC82-AB (Case 419C) 4-pin surface-mount package - measuring 2.0 × 1.25 × 0.9 mm - optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power supply ground reference; must be low-impedance connection to minimize noise coupling. |
| 2 | Vin | Positive input supply; accepts 1.9–6.0 V; requires local 1.0 µF decoupling capacitor. |
| 3 | Vout | Regulated 1.5 V output; stable with ≥0.1 µF ceramic capacitor; drives load up to 80 mA. |
| 4 | N/C | No internal connection - left unconnected or grounded per layout best practice; not an enable pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5 µA typical - extends battery life in always-on sensor nodes and remote controls. |
| Low minimum output capacitance | 0.1 µF ceramic - reduces PCB area and cost vs. traditional LDOs requiring ≥10 µF tantalum. |
| High output voltage accuracy | ±2.0% over temperature and load - ensures reliable operation of precision analog front-ends. |
| Thermal and current protection | Integrated shutdown at ~160 °C and current limit - prevents damage during overload or poor heatsinking. |
| Pb-free, RoHS-compliant packaging | SC82-AB with "G" suffix - meets global environmental compliance requirements for consumer electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/TT | 2.3 µA IQ, 250 mA output, SOT-23-3 package with no enable; 1.5 V output accuracy ±2%. | Higher output current but larger footprint; lacks N/C pin - requires different PCB layout. | Select when >80 mA load current or tighter thermal margin is required; verify SC82-AB replacement feasibility. |
| TPS70615DBVR | 4.5 µA IQ, 150 mA output, SOT-23-5 with enable; 1.5 V output accuracy ±1.5%. | Includes enable pin and higher drive capability, but consumes more quiescent current and requires PCB redesign. | Choose if system-level ON/OFF control is needed; not drop-in due to pin count and enable functionality. |
Compared with MCP1700T-1502E/TT and TPS70615DBVR, the NCP563SQ15T1G offers the lowest quiescent current in the smallest footprint (SC82-AB), making it optimal for ultra-low-power, space-constrained applications where enable control is unnecessary.

FAQ
What is the maximum input voltage rating for the NCP563SQ15T1G?
The NCP563SQ15T1G has a maximum input voltage rating of 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this level risks permanent device damage. For reliable long-term performance, design input rails to remain ≤6.0 V under all conditions including transient spikes, and ensure proper input decoupling with a 1.0 µF capacitor close to the Vin pin.
Does the NCP563SQ15T1G include an enable pin?
No, the NCP563SQ15T1G does not include an enable pin. Pin 4 is designated N/C (no internal connection), distinguishing it from the NCP562 series which uses Pin 4 as an active-enable input. The NCP563SQ15T1G operates continuously when powered - ideal for always-on subsystems where external control logic is unnecessary or handled upstream.
What is the minimum output capacitor required for stable operation of the NCP563SQ15T1G?
The NCP563SQ15T1G requires a minimum output capacitor of 0.1 µF ceramic for stable regulation. This value is confirmed in the datasheet's "Typical Applications" section and electrical characteristics tables. Larger values (e.g., 1.0 µF) improve load transient response and noise rejection but are not mandatory for basic functionality.
Can the NCP563SQ15T1G be used in automotive applications?
The standard NCP563SQ15T1G is not AEC-Q100 qualified. However, the automotive-grade variant NCV563SQ15T1G - identical in electrical specs and SC82-AB packaging - is AEC-Q100 qualified and PPAP capable. For automotive designs, specify NCV563SQ15T1G to meet qualification and traceability requirements; the NCP563SQ15T1G is intended for industrial and consumer portable equipment.
What is the dropout voltage of the NCP563SQ15T1G at 80 mA load and −40 °C?
At 80 mA load and −40 °C, the NCP563SQ15T1G exhibits a dropout voltage of 250 mV, as specified in the Electrical Characteristics table under "Dropout Voltage" for the 1.5 V output version. This means the device maintains regulation as long as Vin ≥ 1.75 V (1.5 V + 0.25 V), supporting operation deep into battery discharge cycles.
