Product details
Overview
NCP562SQ35T1G from onsemi is a fixed-output, low-dropout linear voltage regulator with 3.5 V nominal output, 80 mA output current capability, ultra-low 2.5 µA typical quiescent current, and enable control functionality-designed for battery-powered portable electronics requiring stable low-power supply regulation.
For engineers reviewing the NCP562SQ35T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 80 mA (190 mV), ±2.0% output voltage accuracy over temperature, SC82-AB package compatibility, and enable threshold behavior (1.3 V logic high, 0.3 V logic low).
Technical Context
The NCP562SQ35T1G integrates a PMOS pass transistor, precision voltage reference, error amplifier, thermal shutdown, and current-limit protection in a single die. Its enable input provides active-high ON/OFF control with defined logic thresholds and internal pull-down when unused.
It operates across −40 °C to +85 °C ambient, supports ceramic output capacitors as low as 0.1 µF, and maintains regulation with input voltages up to 6.0 V. Dropout voltage is specified at 190 mV (typical) under 80 mA load at 3.5 V output and full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.5 V ±2.0% - tightly regulated nominal rail for microcontrollers or sensors requiring stable 3.3–3.6 V interface compliance. |
| Quiescent Current | 2.5 µA typical - enables multi-year battery life in always-on IoT endpoints and wearable standby modes. |
| Dropout Voltage | 190 mV @ 80 mA - allows operation down to Vin = 3.69 V while sustaining full rated load at 3.5 V output. |
| Enable Threshold | VTH(HI) = 1.3 V, VTH(LO) = 0.3 V - compatible with 1.8 V/3.3 V GPIO without level-shifting. |
| Output Capacitor Min. | 0.1 µF ceramic - eliminates need for large or specialized ESR-stabilized capacitors; reduces BOM cost and board area. |
| Thermal Shutdown | Activates at ~160 °C - protects against sustained overload or poor PCB thermal design without external circuitry. |
| Operating Temp. | −40 °C to +85 °C - qualified for industrial and consumer portable equipment environments. |
Pinout & Package
Package: SC82-AB (Case 419C), 4-pin surface-mount micro-miniature package (2.2 × 1.35 × 0.95 mm), Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference; must be low-impedance connection to minimize noise and ensure regulation stability. |
| 2 | Vin | Input supply pin; accepts 1.8 V to 6.0 V; requires local 1.0 µF decoupling capacitor per datasheet recommendation. |
| 3 | Vout | Regulated 3.5 V output; connects directly to load; minimum 0.1 µF ceramic capacitor required for stability. |
| 4 | Enable | Active-high digital control input; pulls device into low-IQ shutdown (<0.1 µA) when driven <0.3 V; 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 devices at 10 µA average system load. |
| Enable-controlled shutdown | Reduces total system IQ to <0.1 µA during sleep, supporting deep power-down modes in wearables and remote sensors. |
| ±2.0% output accuracy | Ensures reliable operation of 3.3 V-tolerant I/O peripherals without margining or external trimming. |
| Ceramic capacitor compatibility | Eliminates need for tantalum or aluminum electrolytic capacitors-reducing size, cost, and aging-related failure risk. |
| Thermal and current protection | Integrated safeguards prevent damage during short-circuit events or PCB thermal overload without external components. |
Applications
| Wearable Health Monitor | Portable Barcode Scanner |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3502E/TT | 3.5 V output, 250 mA rating, 1.6 µA IQ, SOT-23-5 package; no enable pin; higher max current but larger footprint. | Lacks enable control; unsuitable where dynamic power gating is required; better for fixed-on systems with higher load headroom. | Select if higher output current (250 mA) is needed and enable functionality is unnecessary. |
| TNIV562SQ35T1G | Identical electrical specs and SC82-AB package; automotive-grade variant (AEC-Q100 qualified, NCV prefix); same marking code LJU. | Qualified for automotive interior modules (e.g., infotainment USB ports); requires PPAP documentation and tighter lot traceability. | Select only for automotive OEM programs requiring AEC-Q100 compliance and controlled change management. |
Compared with MCP1700T-3502E/TT, NCP562SQ35T1G offers precise enable control in a smaller 4-pin package but lower current rating; compared with TNIV562SQ35T1G, it lacks automotive qualification but provides identical performance at lower cost for commercial portable designs.

FAQ
What is the maximum input voltage for the NCP562SQ35T1G?
The NCP562SQ35T1G supports a maximum input voltage of 6.0 V, as specified in its Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable 3.5 V output regulation, Vin must remain ≥ (3.5 V + dropout), with typical dropout at 190 mV under 80 mA load-so minimum functional Vin is ~3.69 V.
Does the NCP562SQ35T1G require an external pull-up on the Enable pin?
No, the NCP562SQ35T1G 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. The pin has no internal pull-up; leaving it floating may cause erratic enable behavior or increased leakage.
Can the NCP562SQ35T1G operate with a 0.1 µF ceramic output capacitor?
Yes, the NCP562SQ35T1G is fully stable with a minimum 0.1 µF ceramic output capacitor, as confirmed in both the Electrical Characteristics and Applications Information sections. Larger values improve transient response and noise rejection, but 0.1 µF meets all stability requirements across temperature and load conditions.
What is the output voltage accuracy of the NCP562SQ35T1G over temperature?
The NCP562SQ35T1G guarantees ±2.0% output voltage accuracy over the full operating ambient temperature range of −40 °C to +85 °C, as stated in the Features section and verified in the Electrical Characteristics table at 25 °C and across temperature sweeps in Figure 5.
Is the NCP562SQ35T1G pin-compatible with the NCP563SQ35T1G?
No, the NCP562SQ35T1G is not pin-compatible with the NCP563SQ35T1G. While both share the SC82-AB package, Pin 4 of the NCP562SQ35T1G is Enable, whereas Pin 4 of the NCP563SQ35T1G is No Connect (N/C). Swapping them without circuit modification will disable the NCP562 or leave its Enable pin unconnected.
