Toshiba Adds Ultra-Small Package 200 mA CMOS LDO to Regular Lineup

February 23, 2011

IRVINE, Calif., Feb. 23, 2011 /PRNewswire/ — Toshiba America Electronic Components, Inc., (TAEC)* has announced the addition of the TCR4SxxWBG and TCR4SxxDWBG series to its family of 200mA CMOS Low Drop-Out regulators (LDOs). Developed by Toshiba Corp., the new single-output LDO regulators feature an ultra-small WCSP4 package which measures 0.79mmx0.79mmx0.50mm and only requires a 0.63 mm2 mounting area. The TCR4SxxWBG and TCR4SxxDWBG series are ideal for applications that require high-density packaging, such as mobile phones, portable audio players and a range of mobile equipment. Toshiba also offers single-output LDO regulators in SMV(SOT-25), UFV and ESV(SOT-553) packages.

An increasing number of low voltage applications require the use of LDOs, as these regulators provide a stable power supply voltage independent of load impedance, and input-voltage variations. Toshiba’s TCR4SxxWBG and TCR4SxxDWBG LDO regulators feature an output voltage range from 1.2V and 3.6V in increments of 50mV. The maximum output current is 200mA and over-current protection functionality is built-in. In addition, Toshiba’s TCR4SxxDWBG LDO regulators provide built-in auto-discharge and control pull-down resistor functions.
