SGM2022
SGM2022 is 250mA LDO Regulator manufactured by SG Micro.
SGM2022 Dual, Low Dropout, 250m A 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 250m A 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 (250m V at 250m A output) to prolong battery life in portable electronics.
Features
- Highly Accurate: ±2%
- Ultra-Low Dropout Voltage:
250m V at 250m A Output
- 190µA No-Load Supply Current
- Thermal-Overload Protection
- Output Current Limit
- 10n A 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 10n A 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.
