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 low-profile surface-mount KTP package allows the device to be used in applications where space is limited.

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
