Toshiba unveils series of enhanced power-line stabilisation regulators

KUALA LUMPUR, Oct 30 -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has launched the ‘TCR3RM Series’ of 32 LDO regulators, bringing enhanced power stabilisation to DC power lines for mobile and wearable devices.

Toshiba, in a statement said the shipments of first products in the series had started and others would follow in turn.

The new TCR3RM series combines a bandgap circuit with a low-pass filter that allows through only extremely low frequencies, and a low-noise, high-speed operational amplifier, to realise an industry-leading high ripple rejection ratio and low output noise voltage.

The 32 products in the lineup have a maximum output current of 300mA and output voltages ranging from 0.9V to 4.5V. Customers can select output voltage by application.

The package is a compact DFN4C package, only 1mm x 1mm, suitable for camera and audio applications, and for the RF circuits of power supply lines in mobile devices requiring high-density mounting, such as smartphones and wearable devices.

The new products also offer an ample ripple rejection ratio and output noise voltage characteristics, even at noise frequencies of 100kHz or higher. This contributes to stabilisation of power supply lines, including high output voltage accuracy.
