3 Description
The TLV773 is a small, low-dropout (LDO) linear
regulator that sources 300mA of output current. This
LDO provides a voltage source with high PSRR and
load and line transient performance that meets the
requirements for a variety of circuits. The TLV773 has
a 1.4V to 5.5V input voltage range and a 0.6V to 3.3V
output voltage range. This flexibility makes the device
useful for multiple applications.
The TLV773 features an internal soft-start circuit to
avoid excessive inrush current, thus minimizing the
input voltage drop during start-up. An active pulldown
circuit quickly discharges the output when the LDO
is disabled and provides a known start-up state. The
EN input allows an external logic signal to enable or
disable the regulated output. The LDO is stable with
small ceramic capacitors, allowing for a small overall
package size. The operating junction temperature
range is from −40°C to +125°C. This LDO is available
in standard SOT-23 (DBV) and 1mm × 1mm X2SON
(DQN) packages.
