SGM2022

Dual, Low Dropout, 150mA

RF - Linear Regulators

GENERAL DESCRIPTION FEATURES The SGM2022 is a dual, low-power, low-dropout, CMOS linear voltage regulators. It operates from a 2.5V to 4.5V input and delivers up to 150mA at each channel. - Highly Accurate: 2% - Ultra-Low Dropout Voltage: - - - - - - - The SGM2022 is the perfect choice for low voltage, low power and RF applications. A low ground current 160µA (both LDO’s enabled and active) makes this part attractive for battery operated power systems. The SGM2022 also offers low dropout voltage (135mV at 150mA output) to prolong battery life in portable electronics. Separate enable pins control each individual LDO output. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. Other features include a 10nA logic-controlled shutdown mode, foldback current limit and thermal shut- down protection. 135mV at 150mA output Low 160µA No-Load Supply Current Low 300µA Operating Supply Current at 150mA Output Thermal-Overload Protection Output Current Limit 10nA Logic-Controlled Shutdown Operating Temperature Range : -40℃ to 85℃ Small Package PIN CONFIGURATIONS（TOP VIEW） SGM2022OUT2GNDEN21265OUT1INDevices come in 6-pin SOT23 package. 3SOT23-EN1APPLICATIONS Cellular Telephones Cordless Telephones PCS Telephones PCMCIA Cards Modems MP3 Player Hand-Held Instruments Palmtop Computers Wireless LAN Portable/Battery-Powered Equipment TYPICAL OPERATION CIRCUIT OUTPUT2OUT21μFOUT11μFINPUTGNDIN1μFOUTPUT1SGM2022ONOFFEN2EN1ONOFF

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. 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.
