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.
