DESCRIPTION
The TPS73219 family is a low-dropout (LDO) voltage
regulator that offers very good line and load transient
response even without the use of an output capacitor.
The TPS73219 is ideal for driving the C2000 MCUs
fron Texas Instruments. The device offers very low
dropout voltage, thereby reducing power loss.
In combination with a voltage supervisor such as the
TPS3808G19 or TPS3808G01, the TPS73219 can
deliver tight V_CORE voltages and generate accurate
power-good signals that meet or exceed power
requirements for the C2000.
The TPS73219 is available in a 5-pin SOT23
package.
