Impala ILC7062CP-25 Sot-23 cmos ldo Datasheet

Impala Linear Corporation
ILC7062
SOT-23 CMOS LDO
General Description
Features
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
2µA of current. Short-circuit protection is standard.
•
•
The part comes in both 3-lead SOT-23 (150mW) and 3lead 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.
Low Power Consumption: typ 2.0µA at VOUT = 5V
All-CMOS design in SOT-23 and SOT-89 packages
gives optimal size and power performances.
Highly accurate output ±2% (±1%)
Maximum output current: 250mA (Limited to 150mW
power dissipation SOT-23, 500mW SOT-89)
Output Voltage Range: 2.0V to 6.0V
