| SGM2022 GENERAL DESCRIPTION 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. The SGM2022 is the perfect choice for low voltage, low power and RF applications. A low ground current 160A (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. Devices come in 6-pin SOT23 package. Dual, Low Dropout, 150mA RF - Linear Regulators FEATURES - Highly Accurate: 2% - Ultra-Low Dropout Voltage: 135mV at 150mA output - Low 160A No-Load Supply Current - Low 300A 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 CONFIGURATIONSTOP VIEW SGM2022 OUT2 GND EN2 1 2 6 5 OUT1 IN 3 SOT23-6 4 EN1 APPLICATIONS 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 OUTPUT2 OUT2 1F OUT1 OUTPUT1 1F INPUT GND IN 1F SGM2022 ON OFF EN2 EN1 ON OFF Shengbang Microelectronics Co, Ltd Tel: 86/451/84348461 www.sg-micro.com REV.
