With the increasing demand for battery-powered IoT devices, communication modules, wearables, and other miniature equipment, the new LDO regulators will help designers meet the ever-growing expectations of engineers.
The new TCR3LM series offers a comprehensive range of over thirty devices covering the input voltage range of 0.8V DC to 5.0V DC with an input voltage (VIN) ranging from 1.4V DC to 5.5V DC. Each device is capable of supplying up to 300mA of output current (IOUT).
The new TCR3LM offers improved performance with a typical output voltage (VDO) of only 137mV. Because the output voltage can be achieved with a lower input voltage, battery consumption is reduced.
In addition, the transient load response has been improved, increasing output stability when the load fluctuates. Toshiba has achieved a typical transient response of
-70 mV / +35 mV at a 2.8 V output, IOUT = 1 mA / 100 mA, while reducing the quiescent current (IB(ON)) to a typical value of only 1.2 μA.
The ultra-compact solution is housed in a DFN4D package measuring only 1.0 mm × 1.0 mm × 0.37 mm. Furthermore, small ceramic capacitors can be used at the input and output, further reducing the overall size of the solution.
Despite their small size, these highly functional LDO regulators offer overcurrent and overtemperature protection, as well as a self-discharge function.
The new TCR3LM series is now in mass production.
