3 Description

The TLV773 is a small, low-dropout (LDO) linear

regulator that can source 300 mA of output current.

This LDO is designed to provide a voltage source

with high PSRR while providing load and line transient

performance that can meet the requirements of a

variety of circuits. With an input voltage range of 1.4 V

to 5.5 V and an output voltage range of 0.6 V to 3.3

V, the TLV773 is flexible enough to be used in 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 +85°C. This LDO is available

in standard SOT-23 (DBV) and 1-mm × 1-mm X2SON

(DQN) packages.
