DESCRIPTION
The TPS735xx 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
response are provided while consuming a very low
46µA (typical) ground current. The TPS735xx is
stable with ceramic capacitors and uses an advanced
BiCMOS fabrication process to yield a typical dropout
voltage of 250mV at 500mA output. The TPS735xx
uses a precision voltage reference and feedback loop
to achieve overall accuracy of 2% (V_OUT > 2.2V) over
all load, line, process, and temperature variations. It
is fully specified from T_J = –40°C to +125°C and is
offered in a low-profile, 2mm x 2mm SON and 3mm ×
3mm SON packages that is ideal for wireless
handsets, printers, and WLAN cards.
