75mA Core Voltage Regulator

Overview

The OT1104 is a CMOS 75mA on-chip core voltage regulator designed for use when a pin for an external decoupling capacitor is not available.

A source follower output stage provides a low impedance at the output at high frequencies, minimizing on chip decoupling requirements for core logic.

Key Features

  • Input voltage range 3.0V – 3.3V.
  • Output voltage 1.2V or 1.8V ±4%.
  • Output short circuit protection.
  • Bundled with Obsidian 1.2V bandgap reference.
  • Power down/enable input.
  • Fast response to current steps.
  • 2% DC line and load regulation.
  • PSRR 45dB @ 1MHz.
  • -40°C to 120°C temperature operation.
  • Base cell area 0.02mm2 in 0.18µ CMOS.
