NCP114AMX300TCG

Product Overview

The NCP114AMX300TCG from Fairchild Semiconductor is a linear voltage regulator IC with Active lifecycle status. It provides a fixed positive 3V output at 300mA. The device is supplied in a 4-UDFN Exposed Pad surface-mount package with a 1.0 x 1.0 mm supplier device package. It accepts input voltages up to 5.5V and includes enable control along with over-current and over-temperature protection. The specified operating temperature range is -40°C to 85°C (TA).

Key Features

• Fixed positive 3V output with 300mA output current.
• Maximum input voltage of 5.5V and maximum dropout of 0.22V at 300mA.
• Quiescent current of 95 µA and PSRR of 75dB at 1kHz.
• Enable control feature with over-current and over-temperature protection.
• Single regulator in a 4-UDFN Exposed Pad surface-mount package.
• Operating temperature range of -40°C to 85°C (TA).

Applications

• 3V supply for low-current microcontroller or sensor subsystems.
• Compact boards needing a fixed 3V rail from an input within the 5.5V maximum.
• Power sequencing or standby control using the enable feature.
• Embedded boards requiring over-current and over-temperature protected 3V rails.

Design & Procurement Notes

When selecting this regulator, verify that the input voltage remains within the 5.5V maximum and that the load current does not exceed the 300mA output current. The 0.22V dropout at 300mA sets the minimum headroom needed for regulation. The enable feature can be used to control operation, and the exposed-pad 4-UDFN package requires appropriate surface-mount pad and thermal layout. The Active lifecycle status should be confirmed during procurement.
