描述 Description

The TLV773 is a small, low-dropout (LDO) linear regulator that can source 300 mA of output current. This LDO is designed to provide a voltage source with high PSRR while providing load and line transient performance that can meet the requirements of a variety of circuits. With an input voltage range of 1.4 V to 5.5 V and an output voltage range of 0.6 V to 3.3 V, the TLV773 is flexible enough to be used in multiple applications.

The TLV773 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 +85°C. This LDO is available in standard SOT-23 (DBV) and 1-mm × 1-mm X2SON (DQN) packages.
