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
- Input voltage range: 0.72 to 1.98 V
- Programmable output voltage: 0.6 to 0.9 V
- Output current in normal mode: 5 mA
- Output current in LP mode: 0.5 mA
- Operating junction temperature range: -40 to 125°C
