Description

The TLV1117 is a linear voltage that provides up to 800mA of output current with a supported input voltage range from 2.7V to 15V. The fixed version of the TLV1117 supports an output range from 1.5V to 5V and the adjustable version supports an output range from 1.25V to 13.8V. This range is designed for a wide variety of applications.

For the adjustable version, use a minimum 1.7mA (typical) load current for stable operation. Place a minimum 10µF tantalum capacitor at the output to improve the transient response and stability.

For the fixed version (new chip), there is no minimum load current requirement on the voltage regulator output. The fixed version of the TLV1117 (new chip), has an internal soft-start feature to reduce inrush current during start-up. This feature helps save space and cost in a design by minimizing input capacitance. The fixed version (new chip) also features a foldback current limit that limits device power dissipation during high-load current faults or shorting events.
