TOSHIBA LAUNCHES HIGH VOLTAGE, LOW CURRENT CONSUMPTION LDO REGULATORS THAT HELP TO LOWER EQUIPMENT STAND-BY POWER

KAWASAKI, Japan, May 23 (Bernama-BUSINESS WIRE) -- Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched the TCR1HF series of LDO regulators that deliver high voltages, a wide input voltage range, and the industry’s lowest[1] stand-by current consumption. Shipment of the first three products in the new series, “TCR1HF18B,” “TCR1HF33B,” and “TCR1HF50B,” which offer output voltages of 1.8V, 3.3V, and 5.0V, respectively, starts today. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20230522005276/en/
To reduce the power consumption of an electronic product in a standby mode when using a power supply circuit with an LDO regulator, it is necessary the power supply is directly connected to the LDO regulator, and power consumption is reduced by turning off the internal circuit.
The new products support a wide input voltage range of 4V to 36V, which allows them to connect to the 4V to 20V power supply used for USB PD[2], and to 24V power supply. They also feature a stand-by current consumption of 1uA (typ.), the lowest in the industry[1], allowing electronic equipment to maintain stand-by operation with very low power consumption. A fast load transient response of -60mV/+50mV (typ.) ensures they deliver stable output voltage during the sudden change in current when a product transitions from stand-by to an operating state.
A reference design “Power multiplexer circuit” using the new product is available.
Toshiba will continue to expand TCR1HF series line-up by adding products with different functions or output voltage values for diverse applications.
Notes:
[1] Stand-by current comparison with LDO regulators with the same ratings. As of May 2023, Toshiba survey.
[2] USB PD(USB Power Delivery): A standard for fast charging that uses USB to provide power up to the highest of 100W.
Applications
Consumer / Personal equipment (Mobile, Note-PC, Home Appliances, etc.)
