(LDK320A) or ± 2 % 25 °C

Output current up to 200 mA

Wide range of output voltages available on

request: fixed from 1.2 V to 12 V with

100 mV step and adjustable

Logic-controlled electronic shutdown

Compatible with ceramic capacitor

OUT

= 1 μF

Current, SOA and thermal protections

Available in SOT23-5L and SOT-89

packages

Temperature range: -40 °C to 125 °C

The LDK320 is a low drop voltage regulator,

which provides a maximum output current of

200 mA from an input voltage in the range of

2.5 V to 18 V, with a typical dropout voltage of

100 mV.

It is stabilized with a ceramic capacitor on the

output.

The very good dynamic characteristic, combined

with low drop voltage and low quiescent current

make it suitable for low power battery-powered

applications.

The enable logic control function allows the

LDK320 to be in shutdown mode by consuming a

total current lower than 1 μA.

This device also includes a short-circuit current

limiting, thermal and SOA protections.
