SGM2045LC
300mA, Low V<sub>IN</sub>, Ultra-Low Noise, Low Start-Up Current, High PSRR Linear Regulator
The SGM2045LC is an ultra-low noise, low VIN, high PSRR 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 1.8V to 5.5V and output voltages are 1.2V, 1.8V and 2.8V.
Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2045LC has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2045LC 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 SGM2045LC is available in a Green XTDFN-1×1-4L package. It operates over an operating temperature range of -40℃ to +125℃.
