The SGM2222 is an ultra-low noise, ultra-high PSRR and low dropout voltage linear regulator for noise-sensitive applications such as RF power supply. It is capable of supplying 200mA output current with typical dropout voltage VDROP of 260mV. The operating input voltage range is from 2V to 20V and output voltage range is from 0V to (VIN - VDROP). It requires an output capacitor with an effective capacitance of 2.2µF or larger to ensure stability.
The SGM2222 uses a high-precision 100μA current source as the reference and a high performance buffer with unit gain for output voltage. Therefore, the SGM2222 supports parallel connection for better noise performance as well as output current capability. And its PSRR, bandwidth, transient response and noise performance are basically not affected by the output voltage.
The SGM2222 opens multiple programmable pins for users to program the current limit, Enable/UVLO threshold, and Power-Good threshold on demand. It also supports fast start-up function. In addition, the SGM2222 integrates the reverse voltage protection, the reverse current protection, the internal current limit protection with foldback and thermal overload protection.
The SGM2222 is available in Green MSOP-10 (Exposed Pad) and TDFN-3×3-10L packages. It operates over an operating temperature range of -40℃ to +125℃.
