SGM2023 Quad, Low Power, Low Dropout, 200mA, RF-Linear Regulators
GENERAL DESCRIPTION
The SGM2023 is a quad, low-power, low-dropout, CMOS linear voltage regulator that operates from 2.5V to 5.5V input and delivers up to 200mA continuous current at each channel. An ultra low ground current (350μA at 0mA output current) makes this part attractive for battery operated power systems.
The SGM2023 also offers low dropout voltage (220mV at 200mA output) to prolong battery life in portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the SGM2023 series’ ultra low output noise (30µVRMS) and high PSRR. An external noise bypass capacitor connected to the device’s BP pin can further reduce the noise level.
Other features include a 10nA logic-controlled shutdown mode, output current limit and thermal shut-down protection.
SGM2023 is available in Green TQFN-3×3-16L package. It operates over an ambient temperature range of -40℃ to +85℃.

CAUTION
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time. Please contact SGMICRO sales office to get the latest datasheet.
