TC2054 - CMOS LDOs

General Description

The TC2054, TC2055 and TC2186 are high accuracy (typically ±0.4%) CMOS upgrades for older (bipolar) low dropout regulators.

Designed specifically for battery-operated systems, the devices’ total supply current is typically 55µA at full load (20 to 60 times lower than in bipolar regulators).

Key Features

  • Very Low Supply Current (55µA Typ. ) for Longer Battery Life.
  • Very Low Dropout Voltage: 140mV (Typ. ) @ 150mA.
  • High Output Voltage Accuracy: ±0.4% (Typ).
  • Standard or Custom Output Voltages.
  • Power-Saving Shutdown Mode.
  • ERROR Output Can Be Used as a Low Battery Detector or Processor Reset Generator.
  • Fast Shutdown Reponse Time: 60µsec (Typ).
  • Over-Current Protection.
  • Space-Saving 5-Pin SOT-23A Package.
  • Pin Compa.
