Product details
Overview
NCP562SQ30T1G from onsemi is a fixed-output, low-dropout linear voltage regulator delivering 3.0 V at up to 80 mA with ultra-low quiescent current (2.5 µA typical), an enable pin for ON/OFF control, and ±2.0% output voltage accuracy over −40 °C to +85 °C - designed for battery-powered portable instruments requiring stable, low-power supply regulation.
For engineers reviewing the NCP562SQ30T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage (200 mV @ 80 mA), SC82-AB package compatibility, enable threshold (1.3 V logic high), thermal shutdown protection, and ceramic capacitor stability (0.1 µF minimum).
Technical Context
The NCP562SQ30T1G integrates a PMOS pass transistor, precision voltage reference, error amplifier, and enable-controlled bias circuitry - enabling fast turn-on response and stable regulation under light-load conditions. Its architecture eliminates ESR dependency, supporting low-ESR ceramic output capacitors as small as 0.1 µF.
It features internal thermal shutdown (trip ~160 °C), current limiting (~150–600 mA depending on VOUT), and reverse-voltage protection. The enable pin operates with TTL-compatible thresholds (VTH(HI) = 1.3 V, VTH(LO) = 0.3 V), allowing direct microcontroller interfacing without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V ±2.0% - tightly regulated rail for MCU core or sensor analog supply. |
| Max Output Current | 80 mA - sufficient for low-power microcontrollers, sensors, and RF modules. |
| Dropout Voltage | 200 mV @ 80 mA - enables operation down to Vin = 3.2 V while maintaining regulation. |
| Quiescent Current | 2.5 µA typical - extends battery life in always-on or sleep-mode applications. |
| Enable Threshold | VEN(HI) = 1.3 V, VEN(LO) = 0.3 V - compatible with 1.8 V/3.3 V GPIO without external pull-ups. |
| Operating Temp | −40 °C to +85 °C - qualified for industrial and consumer portable equipment environments. |
| Noise (100 Hz–100 kHz) | 100 µVRMS - suitable for noise-sensitive analog circuits like ADC references. |
Pinout & Package
The NCP562SQ30T1G is housed in the SC82-AB (Case 419C) surface-mount package - a 4-pin, 2.0 × 1.25 mm micro-miniature footprint with 0.65 mm pitch, optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be low-impedance connection to minimize noise coupling. |
| 2 | Vin | Input supply (up to 6.0 V); requires local 1.0 µF decoupling capacitor per datasheet. |
| 3 | Vout | Regulated 3.0 V output; supports 0.1 µF minimum ceramic capacitor for stability. |
| 4 | Enable | Active-high digital control input; connect to Vin if unused; enables zero-current shutdown mode. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 2.5 µA typical - reduces standby power loss by >95% vs. standard LDOs in battery systems. |
| Ceramic-capacitor stable | 0.1 µF minimum output capacitance - eliminates need for costly tantalum or aluminum electrolytics. |
| Integrated thermal shutdown | ~160 °C trip point - prevents damage during overload or poor PCB thermal design. |
| Enable-controlled operation | Digital ON/OFF via single pin - enables system-level power sequencing and deep-sleep modes. |
| Pb-free, RoHS-compliant | SC82-AB package with "G" suffix - meets global environmental compliance requirements for commercial and industrial use. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 2.0 µA IQ, same 3.0 V output, but no enable pin; SOT-23-3 package (3-pin, no EN). | Lacks digital ON/OFF control - unsuitable for systems requiring active power gating. | Select only when enable functionality is unnecessary and board layout favors SOT-23. |
| TPS70630DBVR | 4.5 µA IQ, 3.0 V output, enable pin, but higher dropout (300 mV @ 80 mA) and larger SOT-23-5 footprint. | Higher dropout limits usable input range; larger package increases PCB area. | Prefer when higher PSRR or wider input voltage margin is needed, despite higher IQ. |

FAQ
What is the maximum input voltage rating for the NCP562SQ30T1G?
The NCP562SQ30T1G has a maximum input voltage rating of 6.0 V, as specified in its Absolute Maximum Ratings table. Exceeding this voltage may cause permanent damage. For reliable operation with margin, design input rails to remain ≤5.5 V under all conditions including transient spikes.
Does the NCP562SQ30T1G require an external pull-up resistor on the Enable pin?
No, the NCP562SQ30T1G does not require an external pull-up on the Enable pin. If unused, the datasheet explicitly states that Enable should be connected directly to Vin to ensure normal operation. Internal biasing eliminates need for external components.
Can the NCP562SQ30T1G operate with a 0.1 µF ceramic output capacitor?
Yes, the NCP562SQ30T1G is fully stable with a 0.1 µF ceramic output capacitor - a key design feature confirmed in the datasheet's Applications Information section. Larger values improve transient response but are not required for basic regulation.
What is the dropout voltage of the NCP562SQ30T1G at 80 mA load and −40 °C?
The dropout voltage of the NCP562SQ30T1G is 200 mV at 80 mA load across the full operating temperature range (−40 °C to +85 °C), as specified in the Electrical Characteristics table under "Dropout Voltage" for 3.0 V output.
Is the NCP562SQ30T1G pin-compatible with the NCP563SQ30T1G?
No, the NCP562SQ30T1G is not pin-compatible with the NCP563SQ30T1G. While both share the SC82-AB package, Pin 4 of the NCP562SQ30T1G is Enable, whereas Pin 4 of the NCP563SQ30T1G is No Connect (N/C). Swapping them risks functional failure due to incorrect pin mapping.
