Toshiba TCR5RG series LDO regulators

Toshiba Electronic Devices & Storage has launched the TCR5RG series of 45 LDO regulators, all housed in thin and compact WCSP4F packages that measure 0.645 x 0.645 mm. The LDO regulators’ high ripple rejection ratio of 100 dB (typ) brings power stabilisation to DC power lines for mobile devices, such as wearables.

The regulators’ high ripple rejection ratio has been achieved by combining a wide-gap circuit, a low-pass filter that allows only extremely low frequencies to pass, and a low-noise, high-speed operational amplifier. They also feature low output voltage noise and high output voltage accuracy. Together, these features enable the regulators to contribute to the stabilisation of power lines.

The line-up includes 45 products with a maximum output current of 500 mA and output voltages in the range of 0.9 to 5 V, allowing users to select the output voltage best suited to their application. The LDO regulators are suitable for power line applications in cameras and small devices such as smartphones and wearables requiring high-density mounting.
