3 Description
The TPS735 family of low-dropout (LDO), low-power
linear regulators offers excellent ac performance with
very low ground current. High power-supply rejection
ratio (PSRR), low noise, fast start-up, and excellent
line and load transient responses are provided while
consuming a very low 46-μA (typical) ground current.
The TPS735 family of devices is stable with ceramic
capacitors and uses an advanced BiCMOS
fabrication process to yield a typical dropout voltage
of 280 mV at 500-mA output. The TPS735 family of
devices uses a precision voltage reference and
feedback loop to achieve overall accuracy of 2%
(V_OUT > 2.2 V) over all load, line, process, and
temperature variations. This family of devices is fully
specified from T_A = –40°C to 125°C and is offered in
a low-profile, 3-mm × 3-mm SON-8 package and a
2-mm x 2-mm SON-6 package.
