NCP502SQ33T1G

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The NCP502SQ33T1G is a fixed-output linear regulator from the NCP502 series, manufactured by onsemi. It provides a stable 3.3 V output with a maximum continuous current of 80 mA. The device utilizes a PMOS power transistor architecture to achieve an ultralow quiescent current of 40 µA. It operates within an input voltage range up to 12 V and maintains regulation across an industrial temperature range of -40 °C to +85 °C. The unit features a typical dropout voltage of 850 mV at full load and offers output voltage accuracy of 2.0%. Integrated protections include current limit and thermal shutdown.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix T1G confirms the standard enable threshold configuration (High: 1.3 V, Low: 0.3 V) as distinct from the NCP502A variant. Confirm SC-70-5 package availability matches design footprint requirements. Ensure RoHS compliance documentation aligns with regional manufacturing standards before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when low static current is critical for battery-operated systems requiring a fixed 3.3 V rail. The 80 mA output capability suits moderate load applications without external pass transistors. Verify that the 12 V maximum input rating accommodates the highest expected supply voltage under all operating conditions.
