SHORT-CIRCUIT
PROTECT
V
SS
250mA CMOS LDO in a SOT-23 package, featuring
120mV of dropout voltage at 100mA and 380mV at 200mA
current levels
The part offers 2% accuracy on outputs, yet draws only
2A of current. Short-circuit protection is standard.
The part comes in both 3-lead SOT-23 (150mW) and 3-
lead SOT-89 (500mW) to handle a variety of voltage and
current levels.
Transient response to load variations have improved in
comparison to the existing series.
Low Power consumption and high accuracy is achieved
through CMOS and laser trimming technologies.
