New LDO has extended temperature range
1 min read
The new XC6505 series from Torex Semiconductor is a 10.5V LDO with a PSRR is 60dB @1kHz, while consuming 5.5µA. It operates with input voltages from 1.7 to 10.5V over a -40 to 105°C temperature range, can deliver output currents up to 200mA and is available with fixed output voltages from 1.5 to 8.0V in 0.1V increments.
The XC6505 has a high output voltage accuracy of +/-1% for VOUT=2.0V (+/-20mV for VOUT<2.0V) and a low voltage dropout of 190mV @ 100mA (VOUT=3.3V).
The device comes with a thermal shutdown circuit that turns off the integrated P-ch driver transistor when the junction temperature of the IC reaches 150°C. It includes a current foldback circuit designed to ensure the output current doesn't excess 300mA when the IC is operating. It also limits the output current to 100mA when a short circuit condition is detected between the VOUT and VSS pins of the IC and it limits the amount of inrush current at start up.
The XC6505 applies a low voltage to its CE pin forces the XC6505 into standby mode and, when entering this mode, the output voltage is brought down to VSS level due to its CL discharge function (XC6505B only).
It is available in USP-6C package for applications that require both a small form factor and a good amount of power dissipation, in SOT-89-5 package for handling even higher power dissipations, and in SOT-25 package.
