DESCRIPTION/ORDERING INFORMATION

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 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 ESR

between 0.2

Ω and 10 Ω.

Unlike 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 device is characterized for operation over the virtual junction temperature range of 0°C to 125°C,

and the TLV1117I device is characterized for operation over the virtual junction temperature range of –40°C to

125°C.
