3 Description

The TPS7C13 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.

The TPS7C13 has a 1.4V to 5.5V input voltage

range and a 0.6V to 3.3V output voltage range. This

flexibility allows the TPS7C13 to be used in multiple

applications.

The TPS7C13 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

design size. The operating junction temperature range

is from −40°C to +125°C. This LDO is available in

standard SOT-23 (DBV) package.
