TCR5RG: Compact LDO Regulators for Stable Power Line Output in Smartphone and Wearable Devices

The newly launched TCR5RG series from Toshiba Electronic Devices & Storage Corporation is a group of 45 LDO regulators all housed in athin, compact WCSP4F package. With a maximumoutput current of 500mAand output voltage in the range of0.9V to 5.0Vthe new devices allow the users to select the output voltage best suited to their applications.

The TCR5RG series offers an industry-leading highripple rejection ratio of 100dBthat is 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. Apart from this the series also features low output voltage noise and high output voltage accuracy for enabling the regulators to contribute to the stabilization of power lines.

These regulators measure 0.645mm x 0.645mm and are suitable for power line applications in cameras and small devices such as smartphones and wearables requiring high-density mounting.

Features of TCR5RG Series
