3 Description

The TLV777 is a small, low-dropout (LDO) linear

regulator that sources 1A 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 1.5V to 5.5V input voltage

range and a 0.6V to 3.3V output voltage range,

the TLV777 is flexible enough for use in multiple

applications.

The TLV777 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 2.9mm × 2.8mm

SOT-23 (DBV) package.
