This makes the LDO especially suitable for power supply applications that are very sensitive to variations in supply voltage (e.g. RFICs). Additionally, without external noise bypass capacitors an ultra-low output noise voltage (VNO) rating of 30µVrms - independent of output current - is achieved. The regulators are dedicated for power supply solutions in Bluetooth devices, cameras, personal audio players, mobile phones and other portable and handheld battery-powered applications. All products in the TCR5SBxx series offer an on/off control function and built in overcurrent protection.
