Output 5 . Se n s e General Description TS39500/1/2/3 are 5A ultra low dropout linear voltage regulators that provide low voltage, high current output with a minimum of ex ternal components . TS39500/1/2/3 offers extremely low dropout (typically 400mV at 5A) and low quiescent current ( typically 36mA at 5A). TS39500/1/2/3 is ideal for PC add- in cards that need to convert from standard 3.3V to 2.5V or 2.5V to 1.8V. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the TS39501/2/3/4 to provide 2.5V from a supply as low as 3V, and 1.8V from a s upply as low as 2.5V. TS39500/1/2/3 also has fas t tr ansient response for heavy switching applications . The device requires only 47uF of output capacitor to maintain s tability and achieve fast tr ansient response. On TS39500/1/2/3, the enable pin may be tied to input voltage if it is not required for enable control.

Exceeding the absolute max imum ratings may be damaged the device. Note 2. The device is not guaranteed to function outside its oper ating rating. Note 3. Devices are ESD sensitive. Handling precautions recommended. Note 4. PD(max) = (TJ(max) - Ta) + ӨJA, where ӨJA depends upon the printed circuit layout. See ”Applications Infor mation” . o Note 5. Output voltage temperature coefficient is ΔVOUT (worst case)+(TJ(max) – TJ(MIN)) where TJ(max) is +125 C and TJMIN) is o - 40 C . Note 6. VDROP = VIN - VOUT when VOUT decreases to 99% of its nominal output voltage with VIN = VOUT + 1. For output voltages below 2.5V, dropout voltage is the input-to-output voltage differential w ith the minimum input voltage being 2.5V. Minimum input operating voltage is 2.5V Note 7. IGND is the quiescent current. IIN = IGND + IOUT Note 8. VEN
