New small surface mount LDO regulators lower power consumption

Toshiba Electronics Europe GmbH has released two new series of small surface mount LDO regulators for employment in the power supply of imaging, mobile devices and audio-visual products. The 40 regulators in the TCR5BM series support a VDO as low as 100mV and a maximum output current of 500mA, while 40 additional devices in the TCR8BM series extend options with a 170mV VDO and 800mA output current. The TCR5BM and TCR8BM series are both offered with VOUT options in the range 0.8V to 3.6V. Both series are ideal for applications that comprise power supplies for MCU, RF devices, and camera CMOS sensors in mobile devices or imaging and audio-visual equipment, which increasingly require lower voltage supplies in the region of 1V. With a 98dB ripple rejection ratio, the new products provide stable operation resistant to high-frequency noise from the external environment and DC-DC converters, both of which are possible causes of improper operation. They also give a fast load transient response that stops malfunctioning due to swift switching of IC operation modes. Quiescent current (TCR5BM=19µA, TCR8BM=20µA) is about 50% less than other high current LDO regulators in the market, allowing lower power consumption in applications and thereby giving longer operating times for battery-driven devices. Both series are housed in the small surface mount DFN5B package with a footprint of just 1.2mm x 1.2mm.
