description/ordering information The TLV1117 is a positive low-dropout voltage regulator, designed to provide up to 800 m A 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 m A, 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 F 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.
