Product details
Overview
NCP562SQ18T1 from onsemi is a fixed-output, low-dropout linear voltage regulator delivering 1.8 V at up to 80 mA with ultra-low quiescent current (2.5 µA typical), integrated enable control, and ±2.0% output voltage accuracy over −40 °C to +85 °C. It serves as a power management IC in battery-powered portable electronics requiring stable low-voltage bias for microcontrollers, sensors, and RF front-ends.
For engineers reviewing the NCP562SQ18T1 datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage (230 mV @ 80 mA), SC82-AB package footprint, enable threshold compatibility (1.3 V logic high), ceramic capacitor support (≥0.1 µF), and thermal shutdown protection.
Technical Context
The NCP562SQ18T1 employs a PMOS pass transistor architecture enabling low dropout operation and eliminating reverse current flow. Its internal circuitry includes a precision voltage reference, error amplifier, current limit, and thermal shutdown - all operating within a single-die SC82-AB package.
It features an active-high enable input (VTH(en) = 1.3 V min) that places the device into standby mode when pulled low, reducing ground current to ≤0.1 µA. The regulator maintains regulation across input voltages from 2.8 V to 6.0 V while sustaining 1.8 V output with ≤40 mV load regulation (10–80 mA) and ≤20 mV line regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.8 V ±2.0% - tightly regulated supply for 1.8 V logic rails and low-power MCU cores. |
| Max Output Current | 80 mA - sufficient for sensor interfaces, BLE SoCs, and small display drivers. |
| Dropout Voltage | 230 mV @ 80 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (3.2 V min). |
| Quiescent Current | 2.5 µA typical - extends battery life in always-on monitoring applications. |
| Enable Threshold | VINH = 1.3 V min, VINL = 0.3 V max - compatible with 1.8 V GPIO without level shifting. |
| Operating Temp | −40 °C to +85 °C - suitable for industrial handhelds and automotive cabin modules. |
| Input Voltage Range | 2.8 V to 6.0 V - supports wide-input battery chemistries and unregulated DC sources. |

Pinout & Package
Package: SC82-AB (Case 419C), 4-pin surface-mount micro-miniature package (2.2 mm × 1.35 mm × 0.95 mm), 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 error. |
| 2 | Vin | Input supply pin; accepts 2.8–6.0 V; requires local 1.0 µF decoupling capacitor. |
| 3 | Vout | Regulated 1.8 V output; drives load and external 0.1–10 µF ceramic capacitor. |
| 4 | Enable | Active-high digital control; connect to Vin if unused; enables <1 µA shutdown current. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 2.5 µA typical - reduces standby power loss in battery-backed systems by >95% vs. standard LDOs. |
| PMOS Pass Device | No body diode reverse conduction - prevents backfeed in multi-rail systems and simplifies power sequencing. |
| Thermal Shutdown | Activates at ~160 °C junction temperature - protects against PCB overheating during sustained overload. |
| Ceramic Cap Stable | Stable with 0.1 µF–10 µF X5R/X7R ceramics - eliminates need for tantalum or aluminum electrolytics. |
| ±2.0% Output Accuracy | Ensures reliable 1.8 V core voltage margin for ARM Cortex-M0+/M3/M4 MCUs and SPI peripherals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1802E/TT | 2.0 µA IQ, same 1.8 V output, but no enable pin; SC-70-5 package (5-pin, larger footprint). | Lacks ON/OFF control - unsuitable for burst-mode power management. | Select only if enable functionality is unnecessary and board space permits SC-70-5 layout. |
| TPS7A0518PDBVR | 250 nA IQ, 1.8 V output, enable pin, but higher dropout (300 mV @ 80 mA) and lower max current (200 mA). | Better for ultra-long-life applications; less suitable for marginal input headroom. | Prefer when battery runtime dominates over input voltage margin; verify thermal performance at 200 mA. |
Compared with MCP1700T-1802E/TT, NCP562SQ18T1 adds critical enable control in a smaller 4-pin SC82-AB package; versus TPS7A0518PDBVR, it trades ultra-low IQ for lower dropout and tighter output accuracy - making it optimal for cost-sensitive, space-constrained 1.8 V systems with moderate battery drain.

FAQ
What is the maximum input voltage for NCP562SQ18T1?
The absolute maximum input voltage for NCP562SQ18T1 is 6.0 V, as specified in the Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable long-term use, design with Vin ≤ 5.5 V under worst-case conditions including ripple and transients.
Does NCP562SQ18T1 require an external pull-up resistor on the Enable pin?
No - the NCP562SQ18T1 does not require an external pull-up on the Enable pin. If unused, the Enable pin must be directly connected to Vin to ensure normal operation. Leaving it floating may cause erratic enable behavior due to noise susceptibility.
Can NCP562SQ18T1 operate with a 0.1 µF ceramic output capacitor?
Yes - the NCP562SQ18T1 is explicitly characterized and stable with a minimum 0.1 µF ceramic output capacitor, as confirmed in both the datasheet Applications Information and Electrical Characteristics sections. Larger values improve transient response but are not required.
What is the dropout voltage of NCP562SQ18T1 at 80 mA load and −40 °C?
The dropout voltage of NCP562SQ18T1 is 230 mV at 80 mA load and across the full operating temperature range (−40 °C to +85 °C), per the Dropout Voltage table in the Electrical Characteristics section. This value is measured at VOUT − 3.0%.
Is NCP562SQ18T1 qualified for automotive applications?
No - NCP562SQ18T1 is not AEC-Q100 qualified. For automotive use, select the NCV562SQ18T1G variant (marked with NCV prefix), which is AEC-Q100 qualified and PPAP capable, as noted in the Ordering Information table and Features list.
