SGM2019-2.8YN5G/TR Description

Short technical summary and product information.

The SGM2019-2.8YN5G/TR is a low power, low noise, and low dropout voltage RF linear regulator manufactured by SG Micro Corp. It is designed to provide a stable output current of up to 300mA with a typical dropout voltage of only 270mV. The device operates from an input voltage range of 2.5V to 5.5V and offers a fixed output voltage of 2.8V.

Key features include a low output noise of 30μVRMS (TYP), high Power Supply Rejection Ratio (PSRR) of 74dB (TYP) at 1kHz, and a low shutdown current of 0.01μA (TYP). The regulator also incorporates essential protection mechanisms such as output current limit and thermal shutdown protection, ensuring reliable operation.

This regulator is available in a compact SOT-23-5 package, suitable for space-constrained applications. It operates across a wide temperature range of -40℃ to +85℃, making it suitable for various environmental conditions. The SGM2019 series is designed for applications including modems, MP3 players, cellular telephones, PCMCIA cards, palmtop computers, and other portable electronics.

Note: This part is not recommended for new designs. SG Micro Corp suggests SGM2036S or SGM2078 as potential replacements.
