SGM2048 1A, Low Noise, Wide Bandwidth, High PSRR, Low Dropout Linear Regulator
■The SGM2048 is a low noise, high PSRR, low dropout voltage linear regulator. It is capable of supplying 1A output current with typical dropout voltage of only 150mV. The operating input voltage range is from 2.2V to 7V. The SGM2048 is available in fixed output voltage versions and an adjustable version that allows the output voltage range from 0.8V to 6V.
■Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2048 has automatic discharge function to quickly discharge VOUT in the disabled status.
■The SGM2048 is available in a Green TDFN-3×3-8CL package. It operates over an operating temperature range of -40°C to +125°C.
●FEATURES
■Operating Input Voltage Range: 2.2V to 7V
■Fixed Outputs of 1.2V, 1.8V, 2.8V, 3.0V, 3.3V, 5.0V
