SGM2122

Dual, Low Dropout,

250mA LDO Regulators

GENERAL DESCRIPTION

FEATURES

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.

 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

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.

 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.
