The new TCR5RG series of 45 LDO regulators from Toshiba is housed in a thin and compact WCSP4F package and offers a high ripple rejection ratio of 100dB (typ.) for enhanced power stabilization to DC power lines in mobile devices. These new regulators combine a wide-gap circuit, a low-pass filter that allows only extremely low frequencies to pass, and a low-noise, high-speed operational amplifier thereby resulting in a high ripple rejection ratio.
Besides, the TCR5RG series regulators feature low output voltage noise and high output voltage accuracy. Measuring 0.645mm x 0.645mm, these regulators are suitable for power line applications in cameras and small devices such as smartphones and wearable devices requiring high-density mounting. The line-up includes 45 products with a maximum output current of 500mA, and output voltages in the range of 0.9V to 5.0V enabling users to select the output voltage best suited to their application.
