SGMICRO SGM2059-1.8XN5G/TR

The SGM2059 is a low VIN, ultra-low noise, high PSRR and low dropout voltage linear regulator. It is capable of supplying 300mA output current with typical dropout voltage of only 72mV. The operating input voltage range is from 1.1V to 5.5V. The fixed output voltage range is from 1.2V to 4.2V and adjustable output voltage range is from 0.793V to 5.0V. Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2059 has automatic discharge function to quickly discharge VOUT in the disabled status. The SGM2059 is suitable for applications which need low noise and fast transient response power supply, such as power supply of camera module in smart phone, etc. The SGM2059 is available in Green SOT-23-5 and SC70-5 packages. It operates over an operating temperature range of -40°C to +125°C.
