Toshiba launches new LDO

Primarily designed for miniature applications fuelled by small-scale batteries, this fresh line-up of devices reduces curtails power consumption, consequently extending the operational lifespan. Given the rising demand for battery-powered IoT equipment/modules, communication modules, wearable gadgets, and other compact apparatus, these new LDO regulators will assist designers in meeting the growing expectations of engineers.

The latest TCR3LM series presents an extensive range of over thirty devices spanning a voltage spectrum from 0.8V DC to 5.0V DC, with an input voltage (VIN) ranging from 1.4V DC to 5.5V DC. Each device can deliver up to 300mA of output current (IOUT).

This new series offers improved drop-out performance, featuring a typical dropout voltage (VDO) as low as 137mV. This reduced dropout voltage enables the attainment of the output voltage with a lower input voltage, effectively mitigating battery drain.

Moreover, enhancements in load transient response augment output stability amidst load fluctuations. Toshiba has achieved a typical transient response of -70mV / +35mV at 2.8V-output, IOUT = 1mA 100mA, while concurrently reducing the quiescent current (IB(ON)) to a typical value of just 1.2μA.

Despite its small size, these feature-rich LDO regulators offer overcurrent and overtemperature protection alongside an auto-discharge function.

The new TCR3LM series, packaged in the ultra-compact DFN4D format measuring merely 1.0mm × 1.0mm × 0.37mm, is now in mass production.
