Low input voltage, high performance LDO linear regulator in TSMC 22ULL with programmable output voltage to supply core logic domains, SRAM arrays or RF/analog domains. It features normal and low-power (LP) operating modes to adjust the amount of output current depending on the application requirements.
Key Benefits
- Low input voltage
- Fast transient response
- Low Power (LP) mode to supply AON domain with low quiescent current
- Operating junction temperature range: -40 to 125°C
