SGM2022
Dual, Low Dropout,
250mA LDO Regulator
GENERAL DESCRIPTION
The SGM2022 is a dual, low-power, low-dropout, CMOS
linear voltage regulator. It operates from a 2.5V to 5.5V
input voltage and delivers up to 250mA at each channel.
The SGM2022 is the perfect choice for low voltage, low
power applications. The ground current is 190μA (both
LDO’s enabled and active) that makes this part attractive
for battery operated power systems. The SGM2022 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
 Thermal-Overload Protection
 Output Current Limit
 10nA Logic-Controlled Shutdown
 Operating Temperature Range: -40℃ to +85℃
 Available in Green SOT-23-6 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, current limit and thermal
shutdown protection.
The SGM2022 is available in Green SOT-23-6 package.
It operates over an ambient temperature range of -40°C
to +85°C.
