Product details
Overview
NCP562SQ30T1 from onsemi is a fixed-output, low-dropout linear regulator (LDO) designed for battery-powered portable electronics. It delivers 3.0 V output at up to 80 mA with ultra-low 2.5 µA quiescent current, 200 mV dropout at 80 mA, and ±2.0% output voltage accuracy - enabling extended runtime in handheld instruments and camcorders.
For engineers reviewing the NCP562SQ30T1 datasheet, pinout, applications, or equivalent options, key selection criteria include enable-controlled ON/OFF functionality, SC82-AB package compatibility, thermal shutdown protection, and ceramic capacitor stability down to 0.1 µF.
Technical Context
The NCP562SQ30T1 integrates a PMOS pass transistor, precision voltage reference, error amplifier, and enable logic in a single die. Its architecture enables stable regulation with no minimum load requirement and supports operation across −40 °C to +85 °C ambient temperature.
It features internal current limiting (150–600 mA depending on output voltage), thermal shutdown activation at ~160 °C, and output short-circuit protection. The enable pin allows external control of regulator state without requiring external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V ±2.0% - ensures stable power rail for 3.0 V logic and analog circuits |
| Max Output Current | 80 mA - sufficient for microcontrollers, sensors, and low-power RF modules |
| Quiescent Current | 2.5 µA typical - minimizes battery drain during standby in always-on devices |
| Dropout Voltage | 200 mV at 80 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline |
| Input Voltage Range | Up to 6.0 V - compatible with common battery chemistries and intermediate supply rails |
| Enable Threshold | VTH(HI) = 1.3 V, VTH(LO) = 0.3 V - compatible with 1.8 V/3.3 V GPIO control |
| Thermal Shutdown | ~160 °C - protects against sustained overload or poor PCB thermal design |
Pinout & Package
The NCP562SQ30T1 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 connected to low-impedance PCB ground plane |
| 2 | Vin | Input supply pin; requires local 1.0 µF decoupling capacitor per datasheet recommendation |
| 3 | Vout | Regulated 3.0 V output; supports ceramic capacitors as low as 0.1 µF |
| 4 | Enable | Active-high digital control input; pulls device into low-power shutdown when <0.3 V |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.5 µA typical - extends battery life in intermittent-sensing applications |
| Enable-controlled operation | Digital ON/OFF control via Pin 4 - eliminates need for external MOSFET switch |
| Ceramic capacitor compatibility | Stable with 0.1 µF output capacitance - reduces BOM cost and board area vs. tantalum |
| High accuracy output | ±2.0% over temperature and load - avoids margining in precision analog subsystems |
| Integrated protection | Current limit, thermal shutdown, and short-circuit protection - enhances system reliability without external components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/MB | 250 mV dropout at 250 mA; 1.6 µA IQ; SOT-23-3 package (no enable) | No enable pin; higher max current but larger footprint and no shutdown control | Select when enable function is unnecessary and higher output current is required |
| TPS70630DBVR | 220 mV dropout at 150 mA; 1.3 µA IQ; SOT-23-5 package with enable and active-low reset | Includes integrated reset generator; slightly higher cost and different pinout | Select when system-level power-on reset signaling is needed alongside regulation |
Compared with MCP1700T-3002E/MB and TPS70630DBVR, the NCP562SQ30T1 offers optimal balance of ultra-low IQ, enable functionality, and minimal SC82-AB footprint - making it preferred for space- and battery-life-critical portable designs where reset signaling is handled externally.

FAQ
What is the maximum input voltage rating for the NCP562SQ30T1?
The NCP562SQ30T1 has an absolute maximum input voltage of 6.0 V. Exceeding this rating may cause permanent damage. For reliable operation, the recommended input range is 3.2 V to 5.5 V when regulating to 3.0 V, ensuring adequate headroom above dropout while maintaining thermal safety under load.
Does the NCP562SQ30T1 require an external pull-up resistor on the Enable pin?
No, the NCP562SQ30T1 does not require an external pull-up resistor on the Enable pin. When unused, the datasheet specifies connecting Enable directly to Vin to ensure default ON operation. Internal biasing is not provided, so floating the pin is not permitted and may cause unpredictable behavior.
Can the NCP562SQ30T1 operate stably with only a 0.1 µF ceramic output capacitor?
Yes, the NCP562SQ30T1 is explicitly characterized and guaranteed stable with a minimum 0.1 µF ceramic output capacitor. This is confirmed in the datasheet's Applications Information section and enables compact, low-cost designs without ESR constraints or additional compensation components.
What is the thermal shutdown threshold temperature for the NCP562SQ30T1?
The NCP562SQ30T1 activates thermal shutdown at approximately 160 °C junction temperature. Once triggered, the device disables output until junction temperature falls below the hysteresis threshold (~140 °C), protecting against sustained overload or inadequate PCB thermal relief.
Is the NCP562SQ30T1 pin-compatible with the NCP563SQ30T1?
No, the NCP562SQ30T1 is not pin-compatible with the NCP563SQ30T1. While both share the SC82-AB package, Pin 4 of the NCP562SQ30T1 is Enable, whereas Pin 4 of the NCP563SQ30T1 is No Connect (N/C). Swapping them without board revision will result in non-functional enable control or unintended behavior.
