3 Description

The TLV774 is a small, low-dropout (LDO) linear

regulator that sources 300mA of output current. This

LDO is designed to provide a voltage source with

high PSRR. This device also provides 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 TLV774 is flexible enough for use in multiple

applications.

The TLV774 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 a standard 1mm × 1mm X2SON (DQN) package.
