GENERAL DEscriptION
The SGM2061 is a low noise, high PSRR and low dropout voltage linear regulator. It is capable of supplying 450mA output current with typical dropout voltage of only 70mV. The operating input voltage range is from 1.9V to 5.5V. The fixed output voltages are 1.8V, 2.5V, 2.8V, 3.0V, 3.3V and 5.0V.
Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2061 has automatic discharge function to discharge VOUT in the disabled status.
The SGM2061is 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 SGM2061 is available in an ultra-thin Green WLCSP-0.64×0.64-4B-A package. It operates over an operating temperature range of -40℃ to +125℃.
