DESCRIPTION
The TPS73534 low-dropout (LDO) voltage regulator
is optimized for use with TI's C2000 controller family
to meet the I/O power rail tolerance requirement. The
device offers very good line and load transient
response, even with very low quiescent current of
46μA.
The device also has superior noise and PSRR
performance to supply noise sensitive circuit blocks.
In combination with a voltage supervisor such as the
TPS3808G01, the TPS73534 can deliver tight V_IO
voltages and generate accurate power-good signals
that meet or exceed power requirements for the
C2000.
The TPS73534 is fully specified from T_J = –40°C to
+125°C and is offered in a 3mm x 3mm SON
package.
