TC1187 - CMOS LDOs

General Description

The TC1070, TC1071 and TC1187 devices are adjustable LDOs designed to supersede a variety of older (bipolar) voltage regulators.

Key Features

  • 50 µA Ground Current for Longer Battery Life.
  • Adjustable Output Voltage.
  • Very Low Dropout Voltage.
  • Choice of 50 mA (TC1070), 100 mA (TC1071) and 150 mA (TC1187) Output.
  • Power-Saving Shutdown mode.
  • Overcurrent and Overtemperature Protection.
  • Space-Saving 5-Pin SOT-23 Package.
  • Pin Compatible with Bipolar Regulators.
