500mA, small-size, high-PSRR low-dropout (LDO) regulator with enable

The TLV775 is a small, low-dropout (LDO) linear

regulator that sources 500mA 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 1.5V to

5.5V input voltage range and a 0.6V to 3.3V output voltage range, the TLV775 is

flexible enough for use in multiple applications.

The TLV775 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 2.9mm × 2.8mm SOT-23 (DBV) package.
