DESCRIPTION
The TLV705 series of low-dropout (LDO) linear
regulators are low quiescent current devices with
excellent line and load transient performance.
Designed for power-sensitive applications, a precision
bandgap and error amplifier provides typical accuracy
of 0.5%. Low output noise, very high power-supply
rejection ratio (PSRR), and low dropout voltage make
this series of LDOs ideal for a wide selection of
battery-operated hand-held equipment. All devices
have a thermal shutdown and current limit for safety.
Furthermore, the TLV705 is stable with an effective
output capacitance of only 0.1 μF. This feature
enables the use of cost-effective capacitors that have
higher bias voltage and temperature derating. The
devices regulate to the specified accuracy with zero
output load. The TLV705P series also provides an
active pull-down circuit to quickly discharge output.
The TLV705 and TLV705P series are both available
in a 0.8-mm × 0.8-mm WCSP with two height options
that are optimal for hand-held applications.
