1A LDO VOLTAGE REGULATOR
DESCRIPTION
The SA1117C is a positive low voltage dropout regulator;
voltage dropout is only 1.2V at 1A.
SA1117C provides two versions: fixed and adjustable versions.
VOUT has a tolerance of less than 1.5% for fixed versions
1.5V, 1.8V, 2.5V, 3.3V, 5.0V and adjustable version or 2%
output accuracy for fixed version 1.2V.
The SA1117C offers some key features include thermal
shutdown and current limiting. It is suitable for all electronic
products.
FEATURES
* 1.5% output accuracy for fixed versions 1.5V, 1.8V, 2.5V,
3.3V, 5.0V and adjustable version
* 2% output accuracy for fixed version 1.2V
* Low Dropout Voltage: 1.2V at 1A output current
* Current Limiting
* Thermal Shutdown
* Temperature Range: -40°C to 125°C
APPLICATIONS
* Laptop, Palmtop, and Notebook
Computers
* Battery Charger
* SCSI-II Active Terminator
* Cellular Phone
* Cordless Telephones
* Battery Powered Systems
* Portable Instrumentation
* SMPS Post-Regulator

Note1: The maximum allowable power dissipation is a function of maximum operating junction temperature, TJ
(max), the junction to ambient thermal resistance, θJA, and the ambient temperature Tamb. The maximum
allowable power dissipation at any ambient temperature is given: PD (max) = (TJ (max) - Tamb)/θJA, exceeding the
maximum allowable power limit will result in excessive die temperature; thus, the regulator will go into thermal
shutdown. The junction to ambient thermal resistance, θJA of some packages may be different, The value of θJA
depends on mounting technique.
