NCP663SQ27T1G

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

The NCP663SQ27T1G is a fixed-output low-dropout linear regulator manufactured by onsemi. It provides a stable 2.7 V output with a maximum continuous current of 100 mA. The device operates within an input voltage range of 3.7 V to 6 V and features a typical quiescent current of 1 µA, with a maximum supply current of 6 µA. It exhibits a maximum dropout voltage of 500 mV at full load and maintains a voltage regulation accuracy of 2%. Integrated protection mechanisms include overcurrent limiting and thermal shutdown. The component is housed in an SC-82AB surface-mount package and supports operation across a temperature range of -40°C to +85°C.
