description/ordering information
The TLV1112 is a low-dropout voltage regulator, designed to provide up to 800 mA of output current at 1.2 V
(typ). All internal circuitry is designed to operate down to 1.1-V input-to-output differential. Dropout voltage is
specified at a maximum of 1.3 V at 800 mA, decreasing at lower load currents.

SLVS562B – DECEMBER 2004 – REVISED APRIL 2005
description/ordering information (continued)
The low-profile surface-mount KTP package allows the device to be used in applications where space is limited.
The TLV1112 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 TLV1112 flows into the load, increasing efficiency.
The TLV1112C is characterized for operation over the virtual junction temperature range of 0°C to 125°C. The
TLV1112I is characterized for operation over the virtual junction temperature range of − 40°C to 125°C.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: Maximum power dissipation is a function of TJ(max),
θ
JA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.

θ
JP is defined as the thermal resistance between the die
junction and the bottom of the exposed pad.
