Capless LDO regulator in TSMC 22ULL

Overview

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 Features

  • 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
