TCR3UM31A - CMOS Low Drop-Out Regulator

Download the TCR3UM31A datasheet PDF. This datasheet also covers the TCR3UM08A variant, as both devices belong to the same cmos low drop-out regulator family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Ultra small package DFN4 (1.0 mm x 1.0 mm; t 0.60 mm (max)).
  • Low quiescent bias current ( IB = 0.34 μA (typ. ) at IOUT = 0 mA, output voltage up to 1.5 V).
  • High Ripple rejection ratio 70 dB at 0.8 V-output.
  • Fast Load transient response -51/+36 mV at 0.8 V-output, IOUT = 1 mA ⇔ 50 mA.
  • Low Drop-Out voltage VIN-VOUT = 196 mV (typ. ) at 3.3 V-output, IOUT = 300 mA.
  • Wide range output voltage line up (VOUT = 0.8 to 5.0 V).
  • High VOUT accura.

TCR3UM series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR3UM series Ultra low quiescent current, Fast Load Transient 300 mA CMOS Low Drop-Out Regulator in ultra small package The TCR3UM series are CMOS general-purpose single-output voltage regulators with an on/off control input, featuring ultra low quiescent bias current and low dropout voltage. These voltage regulators are available in fixed output voltages between 0.8 V and 5.0 V and capable of driving up to 300 mA. They feature Over-current protection, Thermal Shutdown function and Auto-discharge. The TCR3UM series is offered in the ultra small plastic mold package DFN4 (1.0 mm x 1.0 mm; t 0.60 mm (max)) and has a low dropout voltage of 196 mV (3.3 V output, IOUT = 300 mA).
