- SGM2045S
The SGM2045S is an ultra-low noise, low VIN, high PSRR, high accuracy and low dropout voltage linear regulator. It is capable of supplying 300mA output current with typical dropout voltage of only 100mV. The operating input voltage range is from 1.2V to 5.5V and output voltage range is from 1.2V to 3.3V.
Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2045S has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2045S 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 SGM2045S is available in a Green XTDFN-1×1-4L package. It operates over an operating temperature range of -40℃ to +125℃.
