TOSHIBA TCR5RG28A,LF

The TCR5RG series are CMOS general-purpose single-output voltage regulators with an on/off control input, featuring low dropout voltage and ultra high Ripple rejection ratio. These voltage regulators are available in fixed output voltages between 0.9 V and 5.0 V and capable of driving up to 500 mA. They feature Overcurrent protection, Thermal shutdown and Autodischarge. The TCR5RG series is offered in the ultra small plastic mold package WCSP4F (0.645 mm×0.645 mm (Typ.); t 0.33 mm (max)) and has a high ripple rejection ratio of 100 dB (f = 1 KHz, 2.8 V output). As small ceramic input and output capacitors 1.0 μF can be used with the TCR5RG series, these devices are ideal for portable applications that require high-density board assembly such as cellular phones. Weight: 0.26 mg (Typ.)
