3 Description

The TLV772 is a small, adjustable, 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 of a variety of circuits. With a 1.4V

to 5.5V input voltage range and a 0.6V to 3.3V output

voltage range, the TLV772 is flexible enough to be

used in multiple applications.

The TLV772 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 X2SON (DQN) 1mm × 1mm and SOT-23

(DBV) packages.
