SGM2211
SGM2211 is Low Dropout Linear Regulator manufactured by SG Micro.
DESCRIPTION
The SGM2211 is a low noise, high PSRR, fast transient response and low dropout voltage linear regulator. It provides 500m A output current capability. The operating input voltage range is from 2.7V to 20V. The adjustable output voltage range is from 1.2V to (VIN VDROP).
Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2211 has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2211 is available in Green TDFN-2×2-6AL and SOT-23-5 packages. It operates over an operating temperature range of -40℃ to +125℃.
