Toshiba TCR3UF CMOS Linear Integrated Circuits

Toshiba TCR3UF CMOS Linear Integrated Circuits are single output voltage regulators with an on/off control input. The TCR3UF feature ultra-low quiescent bias current and low dropout voltage. These voltage regulators are available in fixed output voltages between 0.8V and 5.0V and capable of driving up to 300mA. The devices also feature overcurrent protection, thermal shutdown function, and an auto-discharge option. The TCR3UF series is offered in general-purpose package SMV (2.9mm x 2.8mm; t 1.1mm (typ.) and has a low dropout voltage of 206mV (3.3V output, I_OUT = 300mA).

Features

Low quiescent bias current (I_B = 0.34μA (typ.) at I_OUT = 0mA, output voltage up to 1.5V)
High Ripple rejection ratio 70dB at 0.8V output
Fast Load transient response -51/+36mV at 0.8V output, I_OUT = 1mA ⇔ 50mA
Low dropout voltage
- V_DO = 206mV (typ.) at 3.3V output, I_OUT = 300mA
