SGM2025 Quad, Low Power, Low Dropout, 200mA, RF-Linear Regulators

Transcription

1 GENERAL DESCRIPTION The SGM2025 is a quad, low-power, low-dropout, CMOS linear voltage regulator that operates from 3.3V to 5.5V input and delivers up to 200mA continuous current at each channel. An ultra low ground current (340µA at 0mA output current) makes this part attractive for battery operated power systems. The SGM2025 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 SGM2025 series ultra low output noise (30µV RMS ) and high PSRR. An external noise bypass capacitor connected to the device s BP pin can further reduce the noise level. Other features include a10na logic-controlled shutdown mode, output current limit and thermal shut-down protection. SGM2025 is available in Green TQFN-16 package. It operates over an ambient temperature range of -40 C to +85 C. FEATURES Low Output Noise: 30µV RMS TYP (10Hz to 100kHz) Low Dropout Voltage: 220mV at 200mA Output Load Current Low 340µA No-Load Supply Current High PSRR: 68dB at 1kHz Thermal-Overload Protection Output Current Limit 10nA Logic Controlled Shutdown -40 to +85 Operating Temperature Range Available in Green TQFN-16 Package APPLICATIONS Cellular Telephones Cordless Telephones PHS Telephones PCMCIA Cards Modems MP3 Player Hand-Held Instruments Palmtop Computers Electronic Planners Portable/Battery-Powered Equipment REV.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 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 2
