Product details
Overview
NCP562SQ50T1G from onsemi is a fixed-output, low-dropout linear voltage regulator with 5.0 V output, 80 mA rated current, 2.5 µA typical quiescent current, and SC82-AB (SC70-4) package. It features an enable pin for ON/OFF control and is designed for battery-powered portable electronics requiring ultra-low standby power.
For engineers reviewing the NCP562SQ50T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 80 mA (140 mV typ), ±2.0% output accuracy, −40 °C to +85 °C operating range, and compatibility with 0.1 µF ceramic output capacitors.
Technical Context
The NCP562SQ50T1G integrates a PMOS pass transistor, precision voltage reference, error amplifier, and thermal/overcurrent protection. Its enable input (pin 4) provides logic-level ON/OFF control with 1.3 V turn-on threshold and 0.3 V turn-off threshold.
Designed for stability with minimal external components, it operates with input voltages from 1.0 V above nominal output (i.e., ≥6.0 V max) and maintains regulation down to 140 mV dropout at full 80 mA load and room temperature. Output voltage temperature coefficient is ±100 ppm/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2.0% - ensures stable supply for 5 V logic or analog circuitry without external feedback. |
| Max Output Current | 80 mA - supports low-power microcontrollers, sensors, and RF modules in portable devices. |
| Quiescent Current | 2.5 µA typical - enables multi-year battery life in always-on sensor nodes or standby circuits. |
| Dropout Voltage | 140 mV @ 80 mA - allows operation from single-cell Li-ion (3.0–4.2 V) with 5 V output via boost stage, or from 5.5 V sources with margin. |
| Operating Temp | −40 °C to +85 °C - qualified for industrial and consumer portable equipment environments. |
| Input Voltage Range | Up to 6.0 V - compatible with common 5 V supply rails and battery-derived inputs with headroom. |
| Enable Threshold | VTH(HI) = 1.3 V, VTH(LO) = 0.3 V - interfaces directly with 1.8 V or 3.3 V GPIO without level-shifting. |
Pinout & Package
Package: SC82-AB (SC70-4), 1.9 mm × 1.3 mm × 0.95 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 variation. |
| 2 | Vin | Input supply pin; accepts up to 6.0 V; requires local 1.0 µF decoupling capacitor. |
| 3 | Vout | Regulated 5.0 V output; stable with ≥0.1 µF ceramic capacitor; drives load up to 80 mA. |
| 4 | Enable | Active-high digital control input; pulls low to disable regulator (IQ < 0.1 µA); connect to Vin if unused. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5 µA typical enables >10-year battery life in coin-cell–powered IoT endpoints. |
| Enable-controlled shutdown | Reduces ground current to <0.1 µA, eliminating leakage paths in sleep-mode systems. |
| Stable with 0.1 µF ceramic output cap | Eliminates need for tantalum or high-ESR capacitors-reducing BOM cost and board area. |
| ±2.0% output accuracy over temp/load | Meets tight tolerance requirements for ADC references and precision analog subsystems. |
| Thermal & current protection | Internal shutdown at ~160 °C and current limit prevent damage during fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-IQ LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-5002E/TT | 2.3 µA IQ, same 5.0 V output, but no enable pin; SOT-23-3 package. | Lacks ON/OFF control; requires external switch or system-level power gating. | Choose when enable functionality is unnecessary and board space permits SOT-23-3 layout. |
| TPS70650DBVR | 4.5 µA IQ, 5.0 V, enable pin, but higher 220 mV dropout at 80 mA; SOT-23-5 package. | Higher dropout limits usable input range; larger package increases footprint. | Prefer only if TI's qualification or support ecosystem is required; not optimal for ultra-low-IQ or space-constrained designs. |
Compared with MCP1700T-5002E/TT and TPS70650DBVR, the NCP562SQ50T1G uniquely combines 2.5 µA quiescent current, integrated enable, 140 mV dropout, and SC82-AB packaging-making it optimal for miniaturized, battery-critical 5 V systems where active power management is essential.

FAQ
What is the maximum input voltage rating for the NCP562SQ50T1G?
The NCP562SQ50T1G has an absolute maximum input voltage of 6.0 V, as specified in the Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable 5.0 V regulation, Vin should be maintained between 5.14 V (5.0 V + 140 mV dropout) and 6.0 V, especially under 80 mA load and elevated temperature.
Does the NCP562SQ50T1G require an external output capacitor, and what is the minimum value?
Yes, the NCP562SQ50T1G requires an external output capacitor for stability. The minimum recommended value is 0.1 µF ceramic, as confirmed in both the datasheet's "Typical Applications" and "Applications Information" sections. Larger values improve load transient response and noise rejection, but 0.1 µF is sufficient for basic regulation.
What is the function of the Enable pin on the NCP562SQ50T1G, and how should it be used?
The Enable pin (pin 4) on the NCP562SQ50T1G controls device activation: pulling it high (≥1.3 V) enables regulation; pulling it low (≤0.3 V) disables the output and reduces quiescent current to <0.1 µA. If unused, the pin must be tied to Vin per datasheet guidance to ensure reliable operation.
Is the NCP562SQ50T1G suitable for automotive applications?
No-the NCP562SQ50T1G is not automotive-qualified. The automotive-grade variant is the NCV562SQ50T1G (with NCV prefix), which is AEC-Q100 qualified and PPAP capable. The NCP562SQ50T1G is rated for −40 °C to +85 °C and intended for industrial and consumer portable equipment.
What is the typical dropout voltage of the NCP562SQ50T1G at 80 mA load and room temperature?
The typical dropout voltage of the NCP562SQ50T1G at 80 mA load and 25 °C is 140 mV, as stated in the Electrical Characteristics table under "Dropout Voltage" for the 5.0 V version. This value increases at lower temperatures and higher loads, reaching up to 250 mV across the full −40 °C to +85 °C range.
