300mA high-PSRR low-IQ adjustable LDO

The TLV772 is a small,

adjustable, low-dropout (LDO) linear regulator that sources 300mA of output current. This

LDO provides a voltage source with high PSRR and 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 TLV772 is flexible

enough to be used in multiple applications.

The TLV772 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 X2SON (DQN) 1mm × 1mm and

SOT-23 (DBV) packages.
