The SGM38122 is a 4-channel LDO PMIC, which has one low output DVDD channel and three high PSRR and low noise AVDD1/2/3 channels.
IN1 input voltage range is from 0.7V to 2.0V. IN2 input voltage range is from 2.5V to 5.5V. IN3 input voltage range is from 1.8V to VIN2.
For DVDD, the SGM38122 uses NMOS architecture without a charge pump. IN1 is used as an input source and IN2 is used as bias voltage. The DVDD output range is from 0.528V to 1.8V. It is capable of supplying 1400mA output current with ultra-low dropout voltage.
For AVDD1/2/3, the SGM38122 uses PMOS architecture with IN2 and IN3 as an input source. All of them can supply 1.504V to 3.424V output voltage with high PSRR performance. The output current limit is 350mA.
The SGM38122 has an external EN pin and internal enable bits. Other features include high resolution output voltage configuration and adjustable hiccup function during OCP. The SGM38122 has automatic discharge function to quickly discharge VOUT in the disabled status. Besides, the SGM38122 supports 1MHz I2C interface with register address automatic increment for continuous writing.
The SGM38122 is qualified for phone camera sensors, camera sensors on wearable device.
The SGM38122 is available in a Green WLCSP- 1.15×1.52-12B package. It operates over an operating temperature range of -40℃ to +85℃.
