150mA small-size high-PSRR low-dropout (LDO) linear regulator

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.
