description

The TLV2217-33 is a low-dropout 3.3-V fixed­voltage regulator. The regulator is capable of
sourcing 500 mA of current with an input-output
differential of 0.5 V, or less. The TLV2217-33
provides internal overcurrent limiting, thermal­overload protection, and overvoltage protection.

The 0.5-V dropout for the TLV2217-33 makes it
ideal for battery applications in 3.3-V logic
systems. For example, battery input voltage to the
regulator can drop as low as 3.8 V, and the
TL V2217-33 can continue to regulate the system.
For higher voltage systems, the TL V2217-33 can
be operated with a continuous input voltage of
12 V.

The TLV2217-33 regulators are characterized for virtual junction temperature operation from 0°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.

NOTES: 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)/

θ

JA

. Operating at the absolute maximum TJ of 150°C can impact reliability. Due to
variation in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be
activated at power levels slightly above or below the rated dissipation.

2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.

COMPENSATION-CAPACITOR SELECTION INFORMATION

The TLV2217-33 is a low-dropout regulator . This means that the capacitance loading is important to the performance
of the regulator because it is a vital part of the control loop. The capacitor value and the equivalent series resistance
(ESR) both affect the control loop and must be defined for the load range and the temperature range. Figures 1 and 2
can be used to establish the capacitance value and ESR range for best regulator performance.
