TCR5RG series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR5RG series Ultra high Ripple rejection ratio, 500 mA CMOS Low Dropout Regulator in ultra small package 1. Description 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 Auto- discharge. The TCR5RG series is offered in the ultra small plastic mold WCSP4F package WCSP4F (0.645 mm x 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 F can be used with the TCR5RG series, these devices are ideal for portable applications that require high-density board assembly such as cellular phones. 2.
