产品描述
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.
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.
The SGM2122 is available in Green SOT-23-6 package. It operates over an ambient temperature range of -40°C to +85°C.
