SGM2122

SGM2122 Dual, Low Dropout, 250mA LDO Regulators GENERAL DESCRIPTION The SGM2122 is a dual, low-power, low-dropout, CMOS linear voltage regulator. It operates from a 2.5V to 5.5V input and delivers up to 250mA at each channel. The SGM2122 is the perfect choice for low voltage, low power. The ground current is 190μA (both LDO’s enabled and active) that makes this part attractive for battery operated power systems. The SGM2122 also offers low dropout voltage (250mV at 250mA output) to prolong battery life in portable electronics. FEATURES  Highly Accurate: ±2%  Ultra-Low Dropout Voltage: 250mV at 250mA Output  190µA No-Load Supply Current  Quick Auto-Discharge in Shutdown Status  Thermal-Overload Protection  Output Current Limit  10nA Logic-Controlled Shutdown  Operating Temperature Range: -40℃ to +85℃  Small Package 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 shutdown protection.
