Product details
Overview
NCP562SQ27T1 from onsemi is a fixed-output, low-dropout linear voltage regulator delivering 2.7 V at up to 80 mA with ultra-low quiescent current (2.5 µA typical), housed in the SC82-AB (SC70-4) package. It integrates PMOS pass transistor, enable control, thermal shutdown, and current limiting - designed for battery-powered portable electronics requiring stable low-voltage supply under light-load conditions.
For engineers reviewing the NCP562SQ27T1 datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage (230 mV @ 80 mA), ±2.0% output accuracy, −40 °C to +85 °C operating range, enable threshold (1.3 V logic high), and compatibility with 0.1 µF ceramic output capacitors.
Technical Context
The NCP562SQ27T1 employs a PMOS pass transistor architecture enabling low dropout and near-zero reverse leakage, with internal reference, error amplifier, and protection circuits (thermal limit, current limit). Its enable input allows precise system-level power sequencing and standby mode control.
It operates across 2.7 V to 6.0 V input range, maintains regulation down to 230 mV dropout at full 80 mA load, and achieves 100 µVRMS output noise (100 Hz–100 kHz) with minimal external components - requiring only 0.1 µF ceramic output capacitance for stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.7 V ±2.0% - tightly regulated nominal rail for MCU core or sensor interface supply. |
| Max Output Current | 80 mA - sufficient for low-power microcontrollers, RF transceivers, or analog sensors. |
| Quiescent Current | 2.5 µA typical - enables multi-year battery life in always-on IoT endpoints. |
| Dropout Voltage | 230 mV @ 80 mA - supports operation from single-cell Li-ion (3.0 V min) or two-cell alkaline. |
| Enable Threshold | VTH(HI) = 1.3 V - compatible with 1.8 V/3.3 V GPIO for clean ON/OFF control. |
| Operating Temp | −40 °C to +85 °C - qualified for industrial and consumer portable equipment environments. |
| Output Noise | 100 µVRMS (100 Hz–100 kHz) - suitable for noise-sensitive analog circuitry without added filtering. |
Pinout & Package
Package: SC82-AB (SC70-4), 1.9 mm × 1.3 mm × 0.9 mm surface-mount, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be low-impedance connection to minimize noise and dropout error. |
| 2 | Vin | Input supply (2.7–6.0 V); requires local 1.0 µF decoupling capacitor per datasheet recommendation. |
| 3 | Vout | Regulated 2.7 V output; stable with ≥0.1 µF ceramic capacitor; supports fast load transient response. |
| 4 | Enable | Active-high digital control: ≥1.3 V enables regulation; ≤0.3 V disables output and reduces IQ to 0.1 µA. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5 µA typical - extends battery runtime in sleep-mode applications without sacrificing startup speed. |
| Low minimum output capacitance | 0.1 µF ceramic - eliminates need for bulky tantalum or high-ESR capacitors, reducing BOM cost and board area. |
| Integrated enable function | Digital ON/OFF control with defined logic thresholds - enables precise power domain sequencing in multi-rail systems. |
| Thermal and current protection | Internal shutdown at ~160 °C and current limit ~150–300 mA - prevents damage during overload or poor PCB thermal design. |
| Pb-free, Halogen-free, RoHS | Compliant with global environmental regulations - supports green manufacturing and export compliance. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2702E/TT | 250 mV dropout @ 250 mA; 1.6 µA IQ; no enable pin; SOT-23-3 package. | Lacks enable control; higher max current but larger footprint; less suitable for sequenced power domains. | Select when enable functionality is unnecessary and higher output current margin is required. |
| TNIV2700024X | 200 mV dropout @ 150 mA; 3.5 µA IQ; enable pin; DFN-4 (1.0×1.0 mm) package. | Smaller footprint and lower dropout, but wider input range (1.7–6.5 V); tighter temp spec (−40 °C to +125 °C). | Prefer for space-constrained designs needing extended temperature support or lower dropout. |
Compared with NCP562SQ27T1, MCP1700T-2702E/TT offers higher current but no enable and larger package, while TNIV2700024X delivers lower dropout and smaller size but targets broader industrial temp ranges - making NCP562SQ27T1 optimal for cost-sensitive, enable-dependent portable designs with standard industrial temperature needs.

FAQ
What is the maximum input voltage rating for the NCP562SQ27T1?
The NCP562SQ27T1 has an absolute maximum input voltage of 6.0 V. Operation above this level risks permanent damage. For reliable long-term performance, the recommended operating input range is 2.7 V to 6.0 V - ensuring proper regulation across the full 230 mV dropout window at 80 mA load. The device includes internal protection against overvoltage stress on the Vin pin.
Does the NCP562SQ27T1 require an external pull-up resistor on the Enable pin?
No, the NCP562SQ27T1 does not require an external pull-up resistor on the Enable pin. When unused, the datasheet specifies connecting Enable directly to Vin to ensure default ON operation. The internal logic threshold (1.3 V high, 0.3 V low) is designed for direct GPIO interfacing; adding external bias may interfere with guaranteed turn-on/turn-off behavior and is not recommended unless specific system-level noise immunity requirements dictate otherwise.
Can the NCP562SQ27T1 operate stably with only a 0.1 µF output capacitor?
Yes, the NCP562SQ27T1 is explicitly characterized and guaranteed stable with a minimum 0.1 µF ceramic output capacitor, as confirmed in the datasheet's "Applications Information" and Figure 1. This low capacitance requirement simplifies layout, reduces cost, and supports miniaturized designs - unlike many older LDOs requiring 1–10 µF tantalum capacitors with specific ESR ranges.
What is the thermal shutdown threshold of the NCP562SQ27T1?
The NCP562SQ27T1 activates thermal shutdown at approximately 160 °C junction temperature, as stated in the "Definitions" section of the datasheet. Once triggered, the regulator disables output until junction temperature falls below the hysteresis threshold (~140 °C), protecting against sustained overtemperature conditions caused by high ambient, poor PCB copper, or excessive power dissipation.
Is the NCP562SQ27T1 pin-compatible with other variants in the NCP562 family?
Yes, all NCP562 variants - including NCP562SQ15T1G, NCP562SQ21T1G, NCP562SQ25T1G, and NCP562SQ27T1G - share identical SC82-AB (SC70-4) pinout and package dimensions. Only the output voltage and top-side marking differ; no PCB redesign is needed when substituting between fixed-voltage versions within the same NCP562 series.
