Product details
Overview
NCP562SQ50T1 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 - designed for battery-powered handheld instruments requiring ultra-low standby power and stable regulation under light loads.
For engineers reviewing the NCP562SQ50T1 datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 80 mA (140 mV typ.), enable functionality, ±2.0% output accuracy over temperature, and compatibility with 0.1 µF ceramic output capacitors.
Technical Context
The NCP562SQ50T1 integrates a PMOS pass transistor, precision voltage reference, error amplifier, thermal shutdown, and current-limit protection. Its enable pin allows external ON/OFF control with logic-compatible thresholds (VTH(H) = 1.3 V, VTH(L) = 0.3 V).
It operates across −40 °C to +85 °C ambient, supports input voltages up to 6.0 V, and maintains regulation down to 140 mV dropout at 80 mA load and 5.0 V output - enabling efficient operation in single-cell Li-ion or dual-cell alkaline systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2.0% - ensures stable supply for 5 V logic, sensors, or analog circuitry without external feedback. |
| Max Output Current | 80 mA - sufficient for low-power microcontrollers, RF modules, or display drivers in portable devices. |
| Quiescent Current | 2.5 µA typ. - enables multi-year battery life in always-on monitoring applications. |
| Dropout Voltage | 140 mV typ. at 80 mA - allows regulation from 5.14 V input, supporting wide input tolerance in aging battery systems. |
| Input Voltage Range | Up to 6.0 V - compatible with USB-powered or dual-cell alkaline inputs without external pre-regulation. |
| Enable Threshold | VEN(H) = 1.3 V min., VEN(L) = 0.3 V max. - interfaces directly with 1.8 V/3.3 V GPIO without level-shifting. |
| Output Capacitor | Min. 0.1 µF ceramic - reduces BOM cost and board space vs. larger tantalum or electrolytic alternatives. |
Pinout & Package
Package: SC82-AB (SC70-4), 1.8 mm × 1.15 mm × 0.9 mm surface-mount package with exposed pad for thermal relief; RoHS-compliant, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be connected to low-impedance PCB ground plane for noise immunity and thermal conduction. |
| 2 | Vin | Input supply pin; accepts 2.0 V to 6.0 V; requires local 1.0 µF decoupling capacitor placed adjacent to pin. |
| 3 | Vout | Regulated 5.0 V output; drives load and 0.1 µF minimum ceramic capacitor; sensitive to trace inductance - place capacitor within 2 mm. |
| 4 | Enable | Active-high digital control; pulls device into <1 µA shutdown when ≤0.3 V; connect to Vin if unused. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 2.5 µA typical - extends battery runtime in IoT sensors and wearables operating >99% in sleep mode. |
| Enable control | Dedicated logic-level pin with defined turn-on/off thresholds - enables precise system power sequencing without external MOSFETs. |
| Stable with 0.1 µF COUT | No ESR requirement - eliminates need for specialized low-ESR capacitors and simplifies sourcing. |
| ±2.0% output accuracy | Over −40 °C to +85 °C and full load range - ensures reliable operation of ADC references and analog front-ends. |
| Thermal shutdown | Activates at ~160 °C junction - protects against sustained overload or poor PCB thermal design without external circuitry. |
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-5002E/TT | 250 mV dropout at 250 mA; 1.6 µA IQ; SOT-23-3 (no enable) | Lacks enable pin; higher current capability but larger dropout limits use below 5.25 V input. | Select when enable control is unnecessary and higher load current (>80 mA) is required. |
| TPS70650DBVR | 220 mV dropout at 150 mA; 1.7 µA IQ; SOT-23-5 (enable + active-low EN) | Active-low enable requires inversion logic; slightly higher dropout reduces usable input range vs. NCP562SQ50T1. | Choose when active-low control aligns with system architecture and tighter output tolerance (±1%) is needed. |
Compared with MCP1700T-5002E/TT and TPS70650DBVR, the NCP562SQ50T1 offers the lowest dropout (140 mV) at 80 mA among these 5 V LDOs - maximizing usable battery voltage range - while retaining an active-high enable pin in the smallest SC70-4 footprint.

FAQ
What is the maximum input voltage rating for the NCP562SQ50T1?
The NCP562SQ50T1 has a maximum input voltage rating of 6.0 V, as specified in the Absolute Maximum Ratings table. Exceeding this voltage may damage the device. Operation above 6.0 V is not supported, even transiently, and requires external clamping or regulation to ensure reliability and longevity of the NCP562SQ50T1.
Does the NCP562SQ50T1 require an external pull-up resistor on the Enable pin?
No, the NCP562SQ50T1 does not require an external pull-up resistor on the Enable pin. If the enable function is unused, the datasheet explicitly states that the pin should be connected directly to Vin. The internal structure supports direct connection without risk of latch-up or undefined behavior, ensuring robust operation of the NCP562SQ50T1 in simplified designs.
What is the minimum output capacitor value required for stable operation of the NCP562SQ50T1?
The NCP562SQ50T1 requires a minimum output capacitor of 0.1 µF ceramic, as confirmed in both the datasheet's "Features" section and "Applications Information" page. This value ensures stability across all operating conditions and load currents up to 80 mA - no ESR constraints apply, making the NCP562SQ50T1 compatible with standard X5R/X7R MLCCs.
Is the NCP562SQ50T1 pin-compatible with the NCP563SQ50T1?
No, the NCP562SQ50T1 is not pin-compatible with the NCP563SQ50T1. While both share the SC82-AB package, the NCP562SQ50T1 uses Pin 4 as Enable, whereas the NCP563SQ50T1 uses Pin 4 as No Connect (N/C). Swapping them without board revision will result in non-functional enable control or floating input - confirming distinct pinouts for the NCP562SQ50T1 and NCP563SQ50T1.
What is the output voltage accuracy specification for the NCP562SQ50T1 over temperature and load?
The NCP562SQ50T1 guarantees ±2.0% output voltage accuracy over the full operating ambient temperature range (−40 °C to +85 °C) and across load currents from 1 mA to 80 mA, as stated in the Electrical Characteristics table. This tolerance includes initial accuracy, line regulation, load regulation, and temperature drift - ensuring consistent performance of the NCP562SQ50T1 in real-world portable applications.
