3 Description

The TLV771 is a small, low-dropout (LDO) linear

regulator that sources 150mA 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 TLV771 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 TLV771 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.
