Capacitor-less low input voltage LDO regulator in TSMC 22ULL with programmable output voltage to supply core logic domain, SRAM array or RF/analog domain. It features normal and low-power (LP) operating modes to adjust the amount of output current depending on the application requirements.
Key Benefits
- Low silicon area
- Fast transient response
- Low BoM cost, no output capacitor required
- Low-power (LP) mode to supply AON domain with low quiescent current
- Operating junction temperature range: -40 to 125°C
