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

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 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.
