Ultra-low IQ TCR3UG Low-Dropout Regulators

Toshiba’s LDO voltage regulators have excellent quiescent currents in extremely small packages

Image of Toshiba TCR3UG Low-Dropout RegulatorsToshiba’s latest LDO technology has created an extremely low quiescent current LDO in the smallest 300 mA package available on the market. The LDO makes a great choice for low cost systems, saving cost and space. The low IQ current (0.38 μA typical) can preserve the battery life of single-cell Li-ion batteries, for example, when powering “always-on systems” or maintaining “standby mode.” Characteristics such as PSRR (70 dB) and transient response (<60 mV) are not sacrificed either, providing users with the ideal LDO with great performance, small package, and low quiescent current.

  • Toshiba’s smallest 0.65 mm x 0.65 mm LDO package
  • Extremely low quiescent current, 0.34 μA typ at 1.2 V output
  • Fixed-output voltage, available between 0.8 V and 5.0 V
  • Regulated voltage stays within ±60 mV during transient load conditions
  • 1% voltage accuracy
  • 70 dB PSRR at 1 kHz
  • Maximum 327 mV dropout at 3.3 V output
  • Thermal shutdown if overheated
  • Inrush current reduction
  • Over-current protection
  • Enable pin
  • (Optional) Automatically discharges output capacitor on shutdown
  • Voltage regulation up to 300 mA
  • Always-on subsystems
  • Re-routing power around PMIC for “active standby” mode
  • NFC power
  • Cameras and CMOS image sensors
  • Single-cell Li-ion batteries
  • Wearable electronics
  • IoT battery-powered modules
