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 requires a minimum of 10 mF of output capacitance for stability. Output capacitors of this size or
larger normally are included in most regulator designs.
Unlike pnp-type regulators, where 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.
