Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ
How is the current limit configured on the LT1175?
The current limit is user-selectable via the ILIM2 and ILIM4 pins. Connecting these pins to VIN sets the limit to 800mA, while leaving them open sets it to 200mA.
Can the LT1175 tolerate a reverse voltage on the output?
Yes, the output can be forced to a reverse voltage without damage or latchup, providing robust protection in certain circuit configurations.
