500mA high-PSRR low-Iq low-dropout regulator with enable

The TLV785 is a small, low-dropout (LDO) linear

regulator that sources 500mA 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 TLV785 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 TLV785 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 SOT-23 (DBV) package.
