SGM2022
Dual, Low Dropout, 150mA
RF - Linear Regulators
GENERAL DESCRIPTION
The SGM2022 is a dual, low-power, low-dropout, CMOS
linear voltage regulators. It operates from a 2.5V to 4.5V
input and delivers up to 150mA at each channel.
The SGM2022 is the perfect choice for low voltage, low
power and RF applications. A low ground current 160µA
(both LDO’s enabled and active) makes this part attractive
for battery operated power systems. The SGM2022 also
offers low dropout voltage (135mV at 150mA 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 shut- down protection.
Devices come in 6-pin SOT23 package.
