Dual, Low Dropout, 150mA RF - Linear Regulators SGM2022 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） SGM2022 Devices come in 6-pin SOT23 package.
