Torex Introduces 10.5V Input, Low Power Consumption, High Speed 200mA LDO Regulator

Torex Semiconductor Ltd. has developed a 10.5V input, low power consumption, high-speed 200mA LDO regulator. The XC6505 series of LDO regulators achieve load-transient response characteristics (PSRR=60dB@1kHz) on a par with high-speed LDO regulators but with the added benefit of a low power consumption of only 5.5µA.

The input voltage range is 1.7 to 10.5V, making this series well suited for specifications that require 5V supply, such as applications that operate on a Li-ion two-cell battery, four dry cell batteries, or a 9V dry cell battery, or in the latter stage of 6V output dc-dc. The maximum output current is 200mA and the output voltage range can be set in steps of 0.1V within a range of 1.5 to 8.0V. Voltage accuracy is ±1.0% (2.0 to 8.0V) or ±20mV (1.5 to 1.9V). Dropout voltage is 190mV at 100mA (VOUT=3.3V). The XC6505 series includes current limitation (300mA, TYP.), short circuit protection (110mA, TYP.), and thermal protection.

The XC6505B series includes a CL discharge function that enables high-speed return of the VOUT pin to the VSS level by quickly discharging the charge. The ultra small USP-6C package, SOT-25 and SOT-89-5 packages are available for selection as appropriate for the application. This is also an environment-friendly product that complies with the RoHS Directive of the EU and is Pb-free.
