The TLV1117 is a positive low-dropout voltage regulator designed to provide up to 800 mA of output current. The device is available in 1.5-V, 1.8-V, 2.5-V, 3.3-V, 5-V, and adjustable-output voltage options. All internal circuitry is designed to operate down to a 1-V, input-to-output differential. Dropout voltage is specified at a maximum of 1.3 V at 800 mA, decreasing at lower load currents.

The TLV1117 is designed to be stable with tantalum and aluminum electrolytic output capacitors having an equivalent series resistance (ESR) between 0.2 Ω and 10 Ω.

Unlike positive-negative-positive (PNP)-type regulators, in which up to 10% of the output current is wasted as quiescent current, the quiescent current of the TLV1117 flows into the load, increasing efficiency.

The TLV1117C is characterized for operation over the virtual junction temperature range of 0°C to +125°C, and the TLV1117I is characterized for operation over the virtual junction temperature range of –40°C to +125°C.
