3 Description
The TPS735-Q1 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-Q1 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-Q1 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 package.
