5a Ultra Low Dropout Positive Voltage Regulator

Datasheet
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 external 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 supply as low as 2.5V. TS39500/1/2/3 also has fast transient
response for heavy switching applications. The device requires only 47uF of output capacitor to maintain stability and
achieve fast transient response.
On TS39500/1/2/3, the enable pin may be tied to input voltage if it is not required for enable control.

... Larger values will help to improve ripple rejection by bypassing the input to the regulator, further improving the integrity of the output voltage. Minimum Load Current The TS39500/1/2/3 is specified between finite loads. If the output current is too small leakage currents dominate and the output voltage rises. A 10mA minimum load current is necessary for proper regulation. Adjustable Regulator Design The adjustable regulator versions (TS39502) is allow to programming the output voltage anywhere between 1 ...

... NPN based regulators require an input voltage of 3.7V at the very least. The TS39500/1/2/3 regulator will provide excellent performance with an input as low as 3.0V or 2.5V respectively. This gives the PNP based regulators a distinct advantage over older, NPN based linear regulators. ...
