Dual, Low Dropout, 150mA
RF-Linear Regulators
SGM2022
GENERAL DESCRIPTION
FEATURES
- Highly Accurate: 2%
- Ultra-Low Dropout Voltage:
135mV at 150mA output
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.
- Low 160µA No-Load Supply Current
- Low 300µA Operating Supply Current
at 150mA Output
- Thermal-Overload Protection
- Output Current Limit
- 10nA Logic-Controlled Shutdown
- Operating Temperature Range : -40℃to 85℃
- Small Package
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
logic-controlled shutdown mode, foldback current limit
and thermal shut- down protection.
