NCP718ASN150T1G

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

The NCP718ASN150T1G is a fixed-output low dropout linear voltage regulator from onsemi, delivering a nominal 1.5 V output with a maximum current of 300 mA. It operates within an input voltage range of 2.5 V to 24 V and features ultra-low quiescent current consumption of typically 4 µA across the full temperature range. The device provides ±2% accuracy over load, line, and temperature variations, along with 60 dB power supply rejection at 1 kHz. It incorporates thermal shutdown, current limiting, and soft-start functionality, housed in a TSOT-23-5 package.

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

Verify the specific ordering suffix 'SN' corresponds to the TSOT-23-5 package configuration required for your design. Confirm that the 'A' variant designation aligns with the active discharge option specifications if applicable to your circuit requirements. Ensure component authenticity through authorized distribution channels to guarantee compliance with RoHS standards.

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

Select this regulator when a wide input voltage range up to 24 V is necessary alongside low ground current consumption. The fixed 1.5 V output eliminates external resistor networks, simplifying board layout compared to adjustable versions. Consider the thermal resistance characteristics of the TSOT-23-5 package for heat dissipation calculations under maximum load conditions.
