Product details
Overview
NCP562SQ33T1G from onsemi is a fixed-output, low-dropout linear regulator (LDO) designed for battery-powered portable electronics. It delivers 3.3 V output at up to 80 mA with 2.5 µA typical quiescent current, ±2.0% output voltage accuracy, and 190 mV dropout at 80 mA - enabling ultra-low-power operation in handheld instruments and camcorders.
For engineers reviewing the NCP562SQ33T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its SC82-AB package footprint, enable-controlled ON/OFF functionality, 0.1 µF minimum ceramic output capacitance requirement, and −40 °C to +85 °C operating ambient range.
Technical Context
The NCP562SQ33T1G integrates a PMOS pass transistor, precision voltage reference, error amplifier, and thermal/overcurrent protection. Its enable input allows system-level power sequencing, and it operates stably with low-ESR ceramic capacitors as small as 0.1 µF.
Designed for minimal board space and low static power, the device achieves 190 mV dropout at full 80 mA load and maintains regulation across input voltages from 3.3 V + 190 mV (min) to 6.0 V (max), with line regulation ≤20 mV over 1.5–4.4 V input range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±2.0% - tightly regulated rail for 3.3 V logic, sensors, or RF front-ends. |
| Max Output Current | 80 mA - sufficient for microcontrollers, memory, and peripheral ICs in compact portable systems. |
| Quiescent Current | 2.5 µA typical - enables multi-year battery life in always-on sensor nodes or standby circuits. |
| Dropout Voltage | 190 mV at 80 mA - supports operation down to Vin = 3.49 V, extending usable battery voltage range. |
| 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 single-cell Li-ion (4.2 V max), two-cell alkaline (3.2 V), or regulated 5 V supplies. |
| Enable Threshold | VTH(HI) = 1.3 V, VTH(LO) = 0.3 V - TTL/CMOS-compatible control with hysteresis for noise-immune switching. |
Pinout & Package
The NCP562SQ33T1G is housed in the SC82-AB (Case 419C) surface-mount package: 2.0 mm × 1.25 mm × 0.9 mm, 4-pin, lead-free, 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 3.49 V to 6.0 V; requires local 1.0 µF decoupling capacitor. |
| 3 | Vout | Regulated 3.3 V output; drives load and requires ≥0.1 µF ceramic capacitor for stability. |
| 4 | Enable | Active-high digital control; pulls low to disable output and reduce IQ to <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 10 µA average-load applications. |
| Stable with 0.1 µF ceramic output cap | No ESR requirement - eliminates need for tantalum or polymer caps, reducing BOM cost and size. |
| Integrated thermal & current limit | Shuts down at ~160 °C junction temp and limits short-circuit current to 150–600 mA - protects PCB and load during fault conditions. |
| ±2.0% output accuracy | Ensures reliable logic-level compatibility and ADC reference stability without external trimming. |
| SC82-AB micro-miniature package | 0.9 mm height and 2.5 mm² footprint - ideal for space-constrained wearables and IoT edge nodes. |
Applications
| Battery-Powered Instruments | Hand-Held Test Equipment |
|---|---|
Use Scenario: Portable multimeter powered by two AA alkaline cells (3.0 V fresh, dropping to 2.4 V). IC Role / Device Role / Timing Role: Primary 3.3 V LDO supplying MCU, display driver, and analog front-end. Use Value: 190 mV dropout allows regulation until battery reaches ~2.5 V, maximizing usable capacity; 2.5 µA IQ extends shelf life. | Use Scenario: Pocket-sized oscilloscope with real-time sampling and LCD interface. IC Role / Device Role / Timing Role: Clean 3.3 V rail for high-speed ADC clocking and FPGA configuration. Use Value: Low output noise (100 µVRMS) prevents sampling jitter; enable pin synchronizes power with wake-up events. |
| Camcorder Power Management | Wireless Sensor Node |
Use Scenario: HD camcorder using single-cell Li-ion (3.0–4.2 V) with burst-mode video recording. IC Role / Device Role / Timing Role: Dedicated 3.3 V supply for image signal processor and SD card interface. Use Value: Stable regulation under fast load transients (10–80 mA steps); 0.1 µF ceramic cap simplifies layout near SoC. | Use Scenario: BLE-enabled temperature node with 10-year coin-cell battery target. IC Role / Device Role / Timing Role: Always-on 3.3 V regulator for ultra-low-power MCU and sensor interface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3302E/TT | 250 mV dropout at 250 mA; 1.6 µA IQ; SOT-23-5 package; no enable pin. | Lacks enable control; higher dropout reduces usable battery range in low-Vin scenarios. | Select when enable is unnecessary and higher output current (250 mA) is required. |
| TPS70633DBVR | 220 mV dropout at 150 mA; 1.3 µA IQ; SOT-23-5; enable pin; ±1% accuracy. | Tighter accuracy and lower IQ, but larger package and higher cost; requires 1 µF min Cout. | Choose for precision rails where 1% tolerance and sub-2 µA IQ justify added cost and footprint. |
Compared with MCP1700T-3302E/TT and TPS70633DBVR, the NCP562SQ33T1G offers the smallest footprint (SC82-AB), integrated enable with defined thresholds, and optimal balance of ultra-low IQ, low dropout, and ceramic-cap stability for space- and battery-limited designs.

FAQ
What is the minimum input voltage required for the NCP562SQ33T1G to maintain regulation?
The NCP562SQ33T1G requires an input voltage at least 190 mV above its 3.3 V nominal output to sustain regulation at 80 mA load, meaning Vin ≥ 3.49 V. At lighter loads, dropout decreases - e.g., ~140 mV at 50 mA - allowing operation down to ~3.44 V. Input must not fall below this margin or regulation fails.
Does the NCP562SQ33T1G require an external pull-up resistor on the Enable pin?
No, the NCP562SQ33T1G does not require an external pull-up on the Enable pin. When unused, the datasheet specifies connecting Enable directly to Vin to ensure default ON operation. The internal circuitry does not mandate external biasing, and adding a pull-up may interfere with controlled shutdown sequencing.
Can the NCP562SQ33T1G operate with a 0.1 µF ceramic output capacitor?
Yes, the NCP562SQ33T1G is explicitly characterized and guaranteed stable with a minimum 0.1 µF ceramic output capacitor - no ESR requirement. This is confirmed in the datasheet's Applications Information section and distinguishes it from older LDOs needing higher-C or specific-ESR capacitors.
What is the thermal shutdown threshold for the NCP562SQ33T1G?
The NCP562SQ33T1G incorporates thermal protection that activates at approximately 160 °C junction temperature, turning off the output to prevent damage. Recovery occurs once the junction cools sufficiently below this threshold. This feature is internal and requires no external components.
Is the NCP562SQ33T1G pin-compatible with the NCP563SQ33T1G?
No, the NCP562SQ33T1G is not pin-compatible with the NCP563SQ33T1G. While both use the SC82-AB package, Pin 4 is Enable on the NCP562SQ33T1G but No Connect (N/C) on the NCP563SQ33T1G. Swapping them without board revision risks incorrect enable behavior or floating inputs.
