300mA, small-size, high-PSRR adjustable low-dropout regulator

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.
