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: -40to +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.

NOTE:
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections
of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause
damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at
any time. Please contact SGMICRO sales office to get the latest datasheet.
