onsemi NCP562SQ15T1G

Overview

NCP562SQ15T1G from onsemi is a fixed-output, low-dropout linear voltage regulator with 1.5 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.

For engineers reviewing the NCP562SQ15T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 80 mA (250 mV max), ±2.0% output accuracy over temperature, enable-controlled ON/OFF functionality, and compatibility with 0.1 µF ceramic output capacitors.

Technical Context

The NCP562SQ15T1G integrates a PMOS pass transistor, precision voltage reference, error amplifier, thermal shutdown, and current-limit protection. Its enable input allows external logic-level control of regulation, with 1.3 V turn-on threshold and 0.3 V turn-off threshold.

It operates across −40 °C to +85 °C ambient, supports input voltages up to 6.0 V, and maintains regulation down to 250 mV dropout at 80 mA load for the 1.5 V variant-enabling stable operation in single-cell Li-ion or multi-cell alkaline systems.

FAQ

What is the maximum input voltage rating for the NCP562SQ15T1G?

The NCP562SQ15T1G has a maximum input voltage rating of 6.0 V, as specified in its Absolute Maximum Ratings table. Exceeding this voltage may cause permanent damage. This rating allows safe operation from common sources including USB (5 V), boosted battery rails, or multi-cell alkaline stacks, while maintaining margin for transient spikes.

Does the NCP562SQ15T1G require an external capacitor on the Enable pin?

No, the NCP562SQ15T1G does not require an external capacitor on the Enable pin. The Enable input is a CMOS-compatible digital control terminal with defined logic thresholds (1.3 V turn-on, 0.3 V turn-off); it draws negligible current and functions reliably when driven directly by MCU GPIO or simple resistor pull-up to Vin. External filtering is unnecessary unless EMI mitigation is required in noisy environments.

Can the NCP562SQ15T1G operate with only a 0.1 µF output capacitor?

Yes, the NCP562SQ15T1G is explicitly designed to be stable with a minimum 0.1 µF ceramic output capacitor, as confirmed in the datasheet's Applications Information section. This eliminates the need for larger or higher-ESR capacitors, reducing BOM cost and board area-ideal for miniaturized portable devices where space and component count are critical constraints.

What is the dropout voltage of the NCP562SQ15T1G at 80 mA load and room temperature?

The dropout voltage of the NCP562SQ15T1G is 250 mV maximum at 80 mA load and 25 °C, per the Electrical Characteristics table. At full load and worst-case temperature (−40 °C to +85 °C), dropout remains ≤250 mV for the 1.5 V version-ensuring regulation can be maintained down to an input voltage of 1.75 V, extending usable battery life in low-voltage systems.

Is the NCP562SQ15T1G pin-compatible with the NCP563SQ15T1G?

No, the NCP562SQ15T1G is not pin-compatible with the NCP563SQ15T1G. While both use the SC82-AB package, the NCP562SQ15T1G has an Enable pin on Pin 4, whereas the NCP563SQ15T1G has a No-Connect (N/C) on Pin 4. Swapping them without PCB revision would leave the Enable function unconnected or misrouted, compromising controlled power-down capability in NCP562-based designs.
